kernel parameters from within another kernel. For more information on the
types of device updates that can be made, as well as the relevant limitations
thereof, see ::cudaGraphKernelNodeUpdatesApply.
<br>
Nodes which are device-updatable have additional restrictions compared to
regular kernel nodes. Firstly, device-updatable nodes cannot be removed
from their graph via ::cuGraphDestroyNode. Additionally, once opted-in
to this functionality, a node cannot opt out, and any attempt to set the
deviceUpdatable attribute to 0 will result in an error. Device-updatable
kernel nodes also cannot have their attributes copied to/from another kernel
node via ::cuGraphKernelNodeCopyAttributes. Graphs containing one or more
device-updatable nodes also do not allow multiple instantiation, and neither
the graph nor its instantiated version can be passed to ::cuGraphExecUpdate.
<br>
If a graph contains device-updatable nodes and updates those nodes from the device
from within the graph, the graph must be uploaded with ::cuGraphUpload before it
is launched. For such a graph, if host-side executable graph updates are made to the
device-updatable nodes, the graph must be uploaded before it is launched again. */

* <b>Deprecated:</b> This flag is deprecated and the behavior enabled
* by this flag is now the default and cannot be disabled.
* Instead, the per-thread stack size can be controlled with ::cuCtxSetLimit().
*
* - ::CU_CTX_COREDUMP_ENABLE: If GPU coredumps have not been enabled globally
* with ::cuCoredumpSetAttributeGlobal or environment variables, this flag can

*
* - ::CU_CTX_USER_COREDUMP_ENABLE: If user-triggered GPU coredumps have not
* been enabled globally with ::cuCoredumpSetAttributeGlobal or environment

* guide under the "GPU core dump support" section.
* It is important to note that the pipe name *must* be set with
* ::cuCoredumpSetAttributeGlobal before creating the context if this flag is

* size, etc). The application can use ::cuCtxGetLimit() to find out exactly
* what the limit has been set to.
*
* Setting each ::CUlimit has its own specific restrictions, so each is
* discussed here.
*
* - ::CU_LIMIT_STACK_SIZE controls the stack size in bytes of each GPU thread.
* The driver automatically increases the per-thread stack size
* for each kernel launch as needed. This size isn't reset back to the
* original value after each launch. Setting this value will take effect
* immediately, and if necessary, the device will block until all preceding
* requested tasks are complete.
*
* - ::CU_LIMIT_PRINTF_FIFO_SIZE controls the size in bytes of the FIFO used
* by the ::printf() device system call. Setting ::CU_LIMIT_PRINTF_FIFO_SIZE
* must be performed before launching any kernel that uses the ::printf()
* device system call, otherwise ::CUDA_ERROR_INVALID_VALUE will be returned.
*
* - ::CU_LIMIT_MALLOC_HEAP_SIZE controls the size in bytes of the heap used
* by the ::malloc() and ::free() device system calls. Setting
* ::CU_LIMIT_MALLOC_HEAP_SIZE must be performed before launching any kernel
* that uses the ::malloc() or ::free() device system calls, otherwise
* ::CUDA_ERROR_INVALID_VALUE will be returned.
*
* - ::CU_LIMIT_DEV_RUNTIME_SYNC_DEPTH controls the maximum nesting depth of
* a grid at which a thread can safely call ::cudaDeviceSynchronize(). Setting
* this limit must be performed before any launch of a kernel that uses the
* device runtime and calls ::cudaDeviceSynchronize() above the default sync
* depth, two levels of grids. Calls to ::cudaDeviceSynchronize() will fail
* with error code ::cudaErrorSyncDepthExceeded if the limitation is
* violated. This limit can be set smaller than the default or up the maximum
* launch depth of 24. When setting this limit, keep in mind that additional
* levels of sync depth require the driver to reserve large amounts of device
* memory which can no longer be used for user allocations. If these
* reservations of device memory fail, ::cuCtxSetLimit() will return
* ::CUDA_ERROR_OUT_OF_MEMORY, and the limit can be reset to a lower value.
* This limit is only applicable to devices of compute capability < 9.0.
* Attempting to set this limit on devices of other compute capability
* versions will result in the error ::CUDA_ERROR_UNSUPPORTED_LIMIT being
* returned.
*
* - ::CU_LIMIT_DEV_RUNTIME_PENDING_LAUNCH_COUNT controls the maximum number of
* outstanding device runtime launches that can be made from the current
* context. A grid is outstanding from the point of launch up until the grid
* is known to have been completed. Device runtime launches which violate
* this limitation fail and return ::cudaErrorLaunchPendingCountExceeded when
* ::cudaGetLastError() is called after launch. If more pending launches than
* the default (2048 launches) are needed for a module using the device
* runtime, this limit can be increased. Keep in mind that being able to
* sustain additional pending launches will require the driver to reserve
* larger amounts of device memory upfront which can no longer be used for
* allocations. If these reservations fail, ::cuCtxSetLimit() will return
* ::CUDA_ERROR_OUT_OF_MEMORY, and the limit can be reset to a lower value.
* This limit is only applicable to devices of compute capability 3.5 and
* higher. Attempting to set this limit on devices of compute capability less
* than 3.5 will result in the error ::CUDA_ERROR_UNSUPPORTED_LIMIT being
* returned.
*
* - ::CU_LIMIT_MAX_L2_FETCH_GRANULARITY controls the L2 cache fetch granularity.
* Values can range from 0B to 128B. This is purely a performance hint and
* it can be ignored or clamped depending on the platform.
*
* - ::CU_LIMIT_PERSISTING_L2_CACHE_SIZE controls size in bytes available for

* - ::CU_FUNC_ATTRIBUTE_SHARED_SIZE_BYTES: The size in bytes of

* - ::CU_FUNC_ATTRIBUTE_CONST_SIZE_BYTES: The size in bytes of user-allocated

* used by each thread of this kernel.
* - ::CU_FUNC_ATTRIBUTE_NUM_REGS: The number of registers used by each thread
* of this kernel.
* - ::CU_FUNC_ATTRIBUTE_PTX_VERSION: The PTX virtual architecture version for
* which the kernel was compiled. This value is the major PTX version * 10
* + the minor PTX version, so a PTX version 1.3 function would return the
* value 13. Note that this may return the undefined value of 0 for cubins
* compiled prior to CUDA 3.0.
* - ::CU_FUNC_ATTRIBUTE_BINARY_VERSION: The binary architecture version for
* which the kernel was compiled. This value is the major binary
* version * 10 + the minor binary version, so a binary version 1.3 function
* would return the value 13. Note that this will return a value of 10 for
* legacy cubins that do not have a properly-encoded binary architecture
* version.
* - ::CU_FUNC_CACHE_MODE_CA: The attribute to indicate whether the kernel has
* been compiled with user specified option "-Xptxas --dlcm=ca" set.
* - ::CU_FUNC_ATTRIBUTE_MAX_DYNAMIC_SHARED_SIZE_BYTES: The maximum size in bytes of
* dynamically-allocated shared memory.
* - ::CU_FUNC_ATTRIBUTE_PREFERRED_SHARED_MEMORY_CARVEOUT: Preferred shared memory-L1
* cache split ratio in percent of total shared memory.
* - ::CU_FUNC_ATTRIBUTE_CLUSTER_SIZE_MUST_BE_SET: If this attribute is set, the
* kernel must launch with a valid cluster size specified.
* - ::CU_FUNC_ATTRIBUTE_REQUIRED_CLUSTER_WIDTH: The required cluster width in
* blocks.
* - ::CU_FUNC_ATTRIBUTE_REQUIRED_CLUSTER_HEIGHT: The required cluster height in
* blocks.
* - ::CU_FUNC_ATTRIBUTE_REQUIRED_CLUSTER_DEPTH: The required cluster depth in

* - ::CU_FUNC_ATTRIBUTE_NON_PORTABLE_CLUSTER_SIZE_ALLOWED: Indicates whether
* the function can be launched with non-portable cluster size. 1 is allowed,
* 0 is disallowed. A non-portable cluster size may only function on the
* specific SKUs the program is tested on. The launch might fail if the
* program is run on a different hardware platform. CUDA API provides

* is 0, ::cuMemAllocManaged returns ::CUDA_ERROR_INVALID_VALUE. The pointer
* is valid on the CPU and on all GPUs in the system that support managed memory.
* All accesses to this pointer must obey the Unified Memory programming model.
*
* \p flags specifies the default stream association for this allocation.
* \p flags must be one of ::CU_MEM_ATTACH_GLOBAL or ::CU_MEM_ATTACH_HOST. If
* ::CU_MEM_ATTACH_GLOBAL is specified, then this memory is accessible from
* any stream on any device. If ::CU_MEM_ATTACH_HOST is specified, then the
* allocation should not be accessed from devices that have a zero value for the
* device attribute ::CU_DEVICE_ATTRIBUTE_CONCURRENT_MANAGED_ACCESS; an explicit call to
* ::cuStreamAttachMemAsync will be required to enable access on such devices.
*
* If the association is later changed via ::cuStreamAttachMemAsync to
* a single stream, the default association as specified during ::cuMemAllocManaged
* is restored when that stream is destroyed. For __managed__ variables, the
* default association is always ::CU_MEM_ATTACH_GLOBAL. Note that destroying a
* stream is an asynchronous operation, and as a result, the change to default
* association won't happen until all work in the stream has completed.
*
* Memory allocated with ::cuMemAllocManaged should be released with ::cuMemFree.
*
* Device memory oversubscription is possible for GPUs that have a non-zero value for the
* device attribute ::CU_DEVICE_ATTRIBUTE_CONCURRENT_MANAGED_ACCESS. Managed memory on
* such GPUs may be evicted from device memory to host memory at any time by the Unified
* Memory driver in order to make room for other allocations.
*
* In a system where all GPUs have a non-zero value for the device attribute
* ::CU_DEVICE_ATTRIBUTE_CONCURRENT_MANAGED_ACCESS, managed memory may not be populated when this
* API returns and instead may be populated on access. In such systems, managed memory can
* migrate to any processor's memory at any time. The Unified Memory driver will employ heuristics to
* maintain data locality and prevent excessive page faults to the extent possible. The application
* can also guide the driver about memory usage patterns via ::cuMemAdvise. The application
* can also explicitly migrate memory to a desired processor's memory via
* ::cuMemPrefetchAsync.
*
* In a multi-GPU system where all of the GPUs have a zero value for the device attribute
* ::CU_DEVICE_ATTRIBUTE_CONCURRENT_MANAGED_ACCESS and all the GPUs have peer-to-peer support
* with each other, the physical storage for managed memory is created on the GPU which is active
* at the time ::cuMemAllocManaged is called. All other GPUs will reference the data at reduced
* bandwidth via peer mappings over the PCIe bus. The Unified Memory driver does not migrate
* memory among such GPUs.
*
* In a multi-GPU system where not all GPUs have peer-to-peer support with each other and
* where the value of the device attribute ::CU_DEVICE_ATTRIBUTE_CONCURRENT_MANAGED_ACCESS
* is zero for at least one of those GPUs, the location chosen for physical storage of managed
* memory is system-dependent.
* - On Linux, the location chosen will be device memory as long as the current set of active
* contexts are on devices that either have peer-to-peer support with each other or have a
* non-zero value for the device attribute ::CU_DEVICE_ATTRIBUTE_CONCURRENT_MANAGED_ACCESS.
* If there is an active context on a GPU that does not have a non-zero value for that device
* attribute and it does not have peer-to-peer support with the other devices that have active
* contexts on them, then the location for physical storage will be 'zero-copy' or host memory.
* Note that this means that managed memory that is located in device memory is migrated to
* host memory if a new context is created on a GPU that doesn't have a non-zero value for
* the device attribute and does not support peer-to-peer with at least one of the other devices
* that has an active context. This in turn implies that context creation may fail if there is
* insufficient host memory to migrate all managed allocations.
* - On Windows, the physical storage is always created in 'zero-copy' or host memory.
* All GPUs will reference the data at reduced bandwidth over the PCIe bus. In these
* circumstances, use of the environment variable CUDA_VISIBLE_DEVICES is recommended to
* restrict CUDA to only use those GPUs that have peer-to-peer support.
* Alternatively, users can also set CUDA_MANAGED_FORCE_DEVICE_ALLOC to a
* non-zero value to force the driver to always use device memory for physical storage.
* When this environment variable is set to a non-zero value, all contexts created in
* that process on devices that support managed memory have to be peer-to-peer compatible
* with each other. Context creation will fail if a context is created on a device that
* supports managed memory and is not peer-to-peer compatible with any of the other
* managed memory supporting devices on which contexts were previously created, even if
* those contexts have been destroyed. These environment variables are described

/**
* \brief Registers an existing host memory range for use by CUDA
*
* Page-locks the memory range specified by \p p and \p bytesize and maps it
* for the device(s) as specified by \p Flags. This memory range also is added
* to the same tracking mechanism as ::cuMemHostAlloc to automatically accelerate
* calls to functions such as ::cuMemcpyHtoD(). Since the memory can be accessed
* directly by the device, it can be read or written with much higher bandwidth
* than pageable memory that has not been registered. Page-locking excessive
* amounts of memory may degrade system performance, since it reduces the amount
* of memory available to the system for paging. As a result, this function is
* best used sparingly to register staging areas for data exchange between
* host and device.
*
* On systems where ::CU_DEVICE_ATTRIBUTE_PAGEABLE_MEMORY_ACCESS_USES_HOST_PAGE_TABLES
* is true, ::cuMemHostRegister will not page-lock the memory range specified
* by \p ptr but only populate unpopulated pages.
*
* The \p Flags parameter enables different options to be specified that
* affect the allocation, as follows.
*
* - ::CU_MEMHOSTREGISTER_PORTABLE: The memory returned by this call will be
* considered as pinned memory by all CUDA contexts, not just the one that
* performed the allocation.
*
* - ::CU_MEMHOSTREGISTER_DEVICEMAP: Maps the allocation into the CUDA address
* space. The device pointer to the memory may be obtained by calling
* ::cuMemHostGetDevicePointer().
*
* - ::CU_MEMHOSTREGISTER_IOMEMORY: The pointer is treated as pointing to some
* I/O memory space, e.g. the PCI Express resource of a 3rd party device.
*
* - ::CU_MEMHOSTREGISTER_READ_ONLY: The pointer is treated as pointing to memory
* that is considered read-only by the device. On platforms without
* ::CU_DEVICE_ATTRIBUTE_PAGEABLE_MEMORY_ACCESS_USES_HOST_PAGE_TABLES, this flag is
* required in order to register memory mapped to the CPU as read-only. Support
* for the use of this flag can be queried from the device attribute
* ::CU_DEVICE_ATTRIBUTE_READ_ONLY_HOST_REGISTER_SUPPORTED. Using this flag with
* a current context associated with a device that does not have this attribute
* set will cause ::cuMemHostRegister to error with CUDA_ERROR_NOT_SUPPORTED.
*
* All of these flags are orthogonal to one another: a developer may page-lock
* memory that is portable or mapped with no restrictions.
*
* The ::CU_MEMHOSTREGISTER_DEVICEMAP flag may be specified on CUDA contexts for
* devices that do not support mapped pinned memory. The failure is deferred
* to ::cuMemHostGetDevicePointer() because the memory may be mapped into
* other CUDA contexts via the ::CU_MEMHOSTREGISTER_PORTABLE flag.
*
* For devices that have a non-zero value for the device attribute
* ::CU_DEVICE_ATTRIBUTE_CAN_USE_HOST_POINTER_FOR_REGISTERED_MEM, the memory
* can also be accessed from the device using the host pointer \p p.
* The device pointer returned by ::cuMemHostGetDevicePointer() may or may not
* match the original host pointer \p ptr and depends on the devices visible to the
* application. If all devices visible to the application have a non-zero value for the
* device attribute, the device pointer returned by ::cuMemHostGetDevicePointer()
* will match the original pointer \p ptr. If any device visible to the application
* has a zero value for the device attribute, the device pointer returned by
* ::cuMemHostGetDevicePointer() will not match the original host pointer \p ptr,
* but it will be suitable for use on all devices provided Unified Virtual Addressing
* is enabled. In such systems, it is valid to access the memory using either pointer
* on devices that have a non-zero value for the device attribute. Note however that

* - ::CUDA_ARRAY3D_LAYERED to enable creation of layered CUDA mipmapped arrays. If this flag is set,
* \p Depth specifies the number of layers, not the depth of a 3D array.
* - ::CUDA_ARRAY3D_SURFACE_LDST to enable surface references to be bound to individual mipmap levels of

* \section CUDA_MALLOC_ASYNC_overview overview
*
* The asynchronous allocator allows the user to allocate and free in stream order.

* will cause undefined behavior.
*
* The allocator is free to reallocate the memory as long as it can guarantee
* that compliant memory accesses will not overlap temporally.
* The allocator may refer to internal stream ordering as well as inter-stream dependencies
* (such as CUDA events and null stream dependencies) when establishing the temporal guarantee.
* The allocator may also insert inter-stream dependencies to establish the temporal guarantee.
*
* \section CUDA_MALLOC_ASYNC_support Supported Platforms

/**
* \defgroup CUDA_UNIFIED Unified Addressing
*
* ___MANBRIEF___ unified addressing functions of the low-level CUDA driver
* API (___CURRENT_FILE___) ___ENDMANBRIEF___
*
* This section describes the unified addressing functions of the
* low-level CUDA driver application programming interface.
*
* @{
*
* \section CUDA_UNIFIED_overview Overview
*
* CUDA devices can share a unified address space with the host.
* For these devices there is no distinction between a device
* pointer and a host pointer -- the same pointer value may be
* used to access memory from the host program and from a kernel
* running on the device (with exceptions enumerated below).
*
* \section CUDA_UNIFIED_support Supported Platforms
*
* Whether or not a device supports unified addressing may be
* queried by calling ::cuDeviceGetAttribute() with the device
* attribute ::CU_DEVICE_ATTRIBUTE_UNIFIED_ADDRESSING.
*
* Unified addressing is automatically enabled in 64-bit processes
*
* \section CUDA_UNIFIED_lookup Looking Up Information from Pointer Values
*
* It is possible to look up information about the memory which backs a
* pointer value. For instance, one may want to know if a pointer points
* to host or device memory. As another example, in the case of device
* memory, one may want to know on which CUDA device the memory
* resides. These properties may be queried using the function
* ::cuPointerGetAttribute()
*
* Since pointers are unique, it is not necessary to specify information
* about the pointers specified to the various copy functions in the
* CUDA API. The function ::cuMemcpy() may be used to perform a copy
* between two pointers, ignoring whether they point to host or device
* memory (making ::cuMemcpyHtoD(), ::cuMemcpyDtoD(), and ::cuMemcpyDtoH()
* unnecessary for devices supporting unified addressing). For
* multidimensional copies, the memory type ::CU_MEMORYTYPE_UNIFIED may be
* used to specify that the CUDA driver should infer the location of the
* pointer from its value.
*
* \section CUDA_UNIFIED_automaphost Automatic Mapping of Host Allocated Host Memory
*
* All host memory allocated in all contexts using ::cuMemAllocHost() and
* ::cuMemHostAlloc() is always directly accessible from all contexts on
* all devices that support unified addressing. This is the case regardless
* of whether or not the flags ::CU_MEMHOSTALLOC_PORTABLE and
* ::CU_MEMHOSTALLOC_DEVICEMAP are specified.
*
* The pointer value through which allocated host memory may be accessed
* in kernels on all devices that support unified addressing is the same
* as the pointer value through which that memory is accessed on the host,
* so it is not necessary to call ::cuMemHostGetDevicePointer() to get the device
* pointer for these allocations.
*
* Note that this is not the case for memory allocated using the flag
* ::CU_MEMHOSTALLOC_WRITECOMBINED, as discussed below.
*
* \section CUDA_UNIFIED_autopeerregister Automatic Registration of Peer Memory
*
* Upon enabling direct access from a context that supports unified addressing
* to another peer context that supports unified addressing using
* ::cuCtxEnablePeerAccess() all memory allocated in the peer context using
* ::cuMemAlloc() and ::cuMemAllocPitch() will immediately be accessible
* by the current context. The device pointer value through
* which any peer memory may be accessed in the current context
* is the same pointer value through which that memory may be
* accessed in the peer context.
*
* \section CUDA_UNIFIED_exceptions Exceptions, Disjoint Addressing
*
* Not all memory may be accessed on devices through the same pointer
* value through which they are accessed on the host. These exceptions
* are host memory registered using ::cuMemHostRegister() and host memory
* allocated using the flag ::CU_MEMHOSTALLOC_WRITECOMBINED. For these
* exceptions, there exists a distinct host and device address for the
* memory. The device address is guaranteed to not overlap any valid host
* pointer range and is guaranteed to have the same value across all
* contexts that support unified addressing.
*
* This device address may be queried using ::cuMemHostGetDevicePointer()
* when a context using unified addressing is current. Either the host
* or the unified device pointer value may be used to refer to this memory
* through ::cuMemcpy() and similar functions using the
* ::CU_MEMORYTYPE_UNIFIED memory type.
*

/**
* \brief Returns information about a pointer
*
* The supported attributes are:
*
* - ::CU_POINTER_ATTRIBUTE_CONTEXT:

* Returns in \p *data the ::CUcontext in which \p ptr was allocated or
* registered.
* The type of \p data must be ::CUcontext *.
*
* If \p ptr was not allocated by, mapped by, or registered with
* a ::CUcontext which uses unified virtual addressing then
* ::CUDA_ERROR_INVALID_VALUE is returned.
*
* - ::CU_POINTER_ATTRIBUTE_MEMORY_TYPE:
*
* Returns in \p *data the physical memory type of the memory that
* \p ptr addresses as a ::CUmemorytype enumerated value.
* The type of \p data must be unsigned int.
*
* If \p ptr addresses device memory then \p *data is set to
* ::CU_MEMORYTYPE_DEVICE. The particular ::CUdevice on which the
* memory resides is the ::CUdevice of the ::CUcontext returned by the
* ::CU_POINTER_ATTRIBUTE_CONTEXT attribute of \p ptr.
*
* If \p ptr addresses host memory then \p *data is set to
* ::CU_MEMORYTYPE_HOST.
*
* If \p ptr was not allocated by, mapped by, or registered with
* a ::CUcontext which uses unified virtual addressing then
* ::CUDA_ERROR_INVALID_VALUE is returned.
*
* If the current ::CUcontext does not support unified virtual
* addressing then ::CUDA_ERROR_INVALID_CONTEXT is returned.
*
* - ::CU_POINTER_ATTRIBUTE_DEVICE_POINTER:
*
* Returns in \p *data the device pointer value through which
* \p ptr may be accessed by kernels running in the current
* ::CUcontext.
* The type of \p data must be CUdeviceptr *.
*
* If there exists no device pointer value through which
* kernels running in the current ::CUcontext may access
* \p ptr then ::CUDA_ERROR_INVALID_VALUE is returned.
*
* If there is no current ::CUcontext then
* ::CUDA_ERROR_INVALID_CONTEXT is returned.
*
* Except in the exceptional disjoint addressing cases discussed
* below, the value returned in \p *data will equal the input
* value \p ptr.
*
* - ::CU_POINTER_ATTRIBUTE_HOST_POINTER:
*
* Returns in \p *data the host pointer value through which
* \p ptr may be accessed by by the host program.
* The type of \p data must be void **.
* If there exists no host pointer value through which
* the host program may directly access \p ptr then
* ::CUDA_ERROR_INVALID_VALUE is returned.
*
* Except in the exceptional disjoint addressing cases discussed
* below, the value returned in \p *data will equal the input
* value \p ptr.
*
* - ::CU_POINTER_ATTRIBUTE_P2P_TOKENS:
*
* Returns in \p *data two tokens for use with the nv-p2p.h Linux
* kernel interface. \p data must be a struct of type
* CUDA_POINTER_ATTRIBUTE_P2P_TOKENS.
*
* \p ptr must be a pointer to memory obtained from :cuMemAlloc().
* Note that p2pToken and vaSpaceToken are only valid for the
* lifetime of the source allocation. A subsequent allocation at
* the same address may return completely different tokens.
* Querying this attribute has a side effect of setting the attribute
* ::CU_POINTER_ATTRIBUTE_SYNC_MEMOPS for the region of memory that
* \p ptr points to.
*
* - ::CU_POINTER_ATTRIBUTE_SYNC_MEMOPS:
*
* A boolean attribute which when set, ensures that synchronous memory operations
* initiated on the region of memory that \p ptr points to will always synchronize.
* See further documentation in the section titled "API synchronization behavior"
* to learn more about cases when synchronous memory operations can
* exhibit asynchronous behavior.
*
* - ::CU_POINTER_ATTRIBUTE_BUFFER_ID:
*
* Returns in \p *data a buffer ID which is guaranteed to be unique within the process.
* \p data must point to an unsigned long long.
*
* \p ptr must be a pointer to memory obtained from a CUDA memory allocation API.
* Every memory allocation from any of the CUDA memory allocation APIs will
* have a unique ID over a process lifetime. Subsequent allocations do not reuse IDs
* from previous freed allocations. IDs are only unique within a single process.
*
*
* - ::CU_POINTER_ATTRIBUTE_IS_MANAGED:
*
* Returns in \p *data a boolean that indicates whether the pointer points to
* managed memory or not.
*
* If \p ptr is not a valid CUDA pointer then ::CUDA_ERROR_INVALID_VALUE is returned.
*
* - ::CU_POINTER_ATTRIBUTE_DEVICE_ORDINAL:
*
* Returns in \p *data an integer representing a device ordinal of a device against
* which the memory was allocated or registered.
*
* - ::CU_POINTER_ATTRIBUTE_IS_LEGACY_CUDA_IPC_CAPABLE:
*
* Returns in \p *data a boolean that indicates if this pointer maps to
* an allocation that is suitable for ::cudaIpcGetMemHandle.
*
* - ::CU_POINTER_ATTRIBUTE_RANGE_START_ADDR:
*
* Returns in \p *data the starting address for the allocation referenced
* by the device pointer \p ptr. Note that this is not necessarily the
* address of the mapped region, but the address of the mappable address
* range \p ptr references (e.g. from ::cuMemAddressReserve).
*
* - ::CU_POINTER_ATTRIBUTE_RANGE_SIZE:
*
* Returns in \p *data the size for the allocation referenced by the device
* pointer \p ptr. Note that this is not necessarily the size of the mapped
* region, but the size of the mappable address range \p ptr references
* (e.g. from ::cuMemAddressReserve). To retrieve the size of the mapped
* region, see ::cuMemGetAddressRange
*
* - ::CU_POINTER_ATTRIBUTE_MAPPED:
*
* Returns in \p *data a boolean that indicates if this pointer is in a
* valid address range that is mapped to a backing allocation.
*
* - ::CU_POINTER_ATTRIBUTE_ALLOWED_HANDLE_TYPES:
*
* Returns a bitmask of the allowed handle types for an allocation that may
* be passed to ::cuMemExportToShareableHandle.
*
* - ::CU_POINTER_ATTRIBUTE_MEMPOOL_HANDLE:
*
* Returns in \p *data the handle to the mempool that the allocation was obtained from.
*
* \par
*
* Note that for most allocations in the unified virtual address space
* the host and device pointer for accessing the allocation will be the
* same. The exceptions to this are
* - user memory registered using ::cuMemHostRegister
* - host memory allocated using ::cuMemHostAlloc with the
* ::CU_MEMHOSTALLOC_WRITECOMBINED flag
* For these types of allocation there will exist separate, disjoint host
* and device addresses for accessing the allocation. In particular
* - The host address will correspond to an invalid unmapped device address
* (which will result in an exception if accessed from the device)
* - The device address will correspond to an invalid unmapped host address
* (which will result in an exception if accessed from the host).
* For these types of allocations, querying ::CU_POINTER_ATTRIBUTE_HOST_POINTER

/**
* \brief Advise about the usage of a given memory range
*
* Note there is a later version of this API, ::cuMemAdvise_v2. It will
* supplant this version in 13.0, which is retained for minor version compatibility.
*
* Advise the Unified Memory subsystem about the usage pattern for the memory range
* starting at \p devPtr with a size of \p count bytes. The start address and end address of the memory
* range will be rounded down and rounded up respectively to be aligned to CPU page size before the
* advice is applied. The memory range must refer to managed memory allocated via ::cuMemAllocManaged
* or declared via __managed__ variables. The memory range could also refer to system-allocated pageable
* memory provided it represents a valid, host-accessible region of memory and all additional constraints
* imposed by \p advice as outlined below are also satisfied. Specifying an invalid system-allocated pageable
* memory range results in an error being returned.
*
* The \p advice parameter can take the following values:
* - ::CU_MEM_ADVISE_SET_READ_MOSTLY: This implies that the data is mostly going to be read
* from and only occasionally written to. Any read accesses from any processor to this region will create a
* read-only copy of at least the accessed pages in that processor's memory. Additionally, if ::cuMemPrefetchAsync
* is called on this region, it will create a read-only copy of the data on the destination processor.
* If any processor writes to this region, all copies of the corresponding page will be invalidated
* except for the one where the write occurred. The \p device argument is ignored for this advice.
* Note that for a page to be read-duplicated, the accessing processor must either be the CPU or a GPU
* that has a non-zero value for the device attribute ::CU_DEVICE_ATTRIBUTE_CONCURRENT_MANAGED_ACCESS.
* Also, if a context is created on a device that does not have the device attribute
* ::CU_DEVICE_ATTRIBUTE_CONCURRENT_MANAGED_ACCESS set, then read-duplication will not occur until
* all such contexts are destroyed.
* If the memory region refers to valid system-allocated pageable memory, then the accessing device must
* have a non-zero value for the device attribute ::CU_DEVICE_ATTRIBUTE_PAGEABLE_MEMORY_ACCESS for a read-only
* copy to be created on that device. Note however that if the accessing device also has a non-zero value for the
* device attribute ::CU_DEVICE_ATTRIBUTE_PAGEABLE_MEMORY_ACCESS_USES_HOST_PAGE_TABLES, then setting this advice
* will not create a read-only copy when that device accesses this memory region.
*
* - ::CU_MEM_ADVISE_UNSET_READ_MOSTLY: Undoes the effect of ::CU_MEM_ADVISE_SET_READ_MOSTLY and also prevents the
* Unified Memory driver from attempting heuristic read-duplication on the memory range. Any read-duplicated
* copies of the data will be collapsed into a single copy. The location for the collapsed
* copy will be the preferred location if the page has a preferred location and one of the read-duplicated
* copies was resident at that location. Otherwise, the location chosen is arbitrary.
*
* - ::CU_MEM_ADVISE_SET_PREFERRED_LOCATION: This advice sets the preferred location for the
* data to be the memory belonging to \p device. Passing in CU_DEVICE_CPU for \p device sets the
* preferred location as host memory. If \p device is a GPU, then it must have a non-zero value for the
* device attribute ::CU_DEVICE_ATTRIBUTE_CONCURRENT_MANAGED_ACCESS. Setting the preferred location
* does not cause data to migrate to that location immediately. Instead, it guides the migration policy
* when a fault occurs on that memory region. If the data is already in its preferred location and the
* faulting processor can establish a mapping without requiring the data to be migrated, then
* data migration will be avoided. On the other hand, if the data is not in its preferred location
* or if a direct mapping cannot be established, then it will be migrated to the processor accessing
* it. It is important to note that setting the preferred location does not prevent data prefetching
* done using ::cuMemPrefetchAsync.
* Having a preferred location can override the page thrash detection and resolution logic in the Unified
* Memory driver. Normally, if a page is detected to be constantly thrashing between for example host and device
* memory, the page may eventually be pinned to host memory by the Unified Memory driver. But
* if the preferred location is set as device memory, then the page will continue to thrash indefinitely.
* If ::CU_MEM_ADVISE_SET_READ_MOSTLY is also set on this memory region or any subset of it, then the
* policies associated with that advice will override the policies of this advice, unless read accesses from
* \p device will not result in a read-only copy being created on that device as outlined in description for
* the advice ::CU_MEM_ADVISE_SET_READ_MOSTLY.
* If the memory region refers to valid system-allocated pageable memory, then \p device must have a non-zero
* value for the device attribute ::CU_DEVICE_ATTRIBUTE_PAGEABLE_MEMORY_ACCESS.
*
* - ::CU_MEM_ADVISE_UNSET_PREFERRED_LOCATION: Undoes the effect of ::CU_MEM_ADVISE_SET_PREFERRED_LOCATION
* and changes the preferred location to none.
*
* - ::CU_MEM_ADVISE_SET_ACCESSED_BY: This advice implies that the data will be accessed by \p device.
* Passing in ::CU_DEVICE_CPU for \p device will set the advice for the CPU. If \p device is a GPU, then
* the device attribute ::CU_DEVICE_ATTRIBUTE_CONCURRENT_MANAGED_ACCESS must be non-zero.
* This advice does not cause data migration and has no impact on the location of the data per se. Instead,
* it causes the data to always be mapped in the specified processor's page tables, as long as the
* location of the data permits a mapping to be established. If the data gets migrated for any reason,
* the mappings are updated accordingly.
* This advice is recommended in scenarios where data locality is not important, but avoiding faults is.
* Consider for example a system containing multiple GPUs with peer-to-peer access enabled, where the
* data located on one GPU is occasionally accessed by peer GPUs. In such scenarios, migrating data
* over to the other GPUs is not as important because the accesses are infrequent and the overhead of
* migration may be too high. But preventing faults can still help improve performance, and so having
* a mapping set up in advance is useful. Note that on CPU access of this data, the data may be migrated
* to host memory because the CPU typically cannot access device memory directly. Any GPU that had the
* ::CU_MEM_ADVISE_SET_ACCESSED_BY flag set for this data will now have its mapping updated to point to the
* page in host memory.
* If ::CU_MEM_ADVISE_SET_READ_MOSTLY is also set on this memory region or any subset of it, then the
* policies associated with that advice will override the policies of this advice. Additionally, if the
* preferred location of this memory region or any subset of it is also \p device, then the policies
* associated with ::CU_MEM_ADVISE_SET_PREFERRED_LOCATION will override the policies of this advice.
* If the memory region refers to valid system-allocated pageable memory, then \p device must have a non-zero
* value for the device attribute ::CU_DEVICE_ATTRIBUTE_PAGEABLE_MEMORY_ACCESS. Additionally, if \p device has
* a non-zero value for the device attribute ::CU_DEVICE_ATTRIBUTE_PAGEABLE_MEMORY_ACCESS_USES_HOST_PAGE_TABLES,
* then this call has no effect.
*
* - ::CU_MEM_ADVISE_UNSET_ACCESSED_BY: Undoes the effect of ::CU_MEM_ADVISE_SET_ACCESSED_BY. Any mappings to
* the data from \p device may be removed at any time causing accesses to result in non-fatal page faults.
* If the memory region refers to valid system-allocated pageable memory, then \p device must have a non-zero
* value for the device attribute ::CU_DEVICE_ATTRIBUTE_PAGEABLE_MEMORY_ACCESS. Additionally, if \p device has
* a non-zero value for the device attribute ::CU_DEVICE_ATTRIBUTE_PAGEABLE_MEMORY_ACCESS_USES_HOST_PAGE_TABLES,

* \brief Query an attribute of a given memory range
*
* Query an attribute about the memory range starting at \p devPtr with a size of \p count bytes. The
* memory range must refer to managed memory allocated via ::cuMemAllocManaged or declared via
* __managed__ variables.
*
* The \p attribute parameter can take the following values:
* - ::CU_MEM_RANGE_ATTRIBUTE_READ_MOSTLY: If this attribute is specified, \p data will be interpreted
* as a 32-bit integer, and \p dataSize must be 4. The result returned will be 1 if all pages in the given
* memory range have read-duplication enabled, or 0 otherwise.
* - ::CU_MEM_RANGE_ATTRIBUTE_PREFERRED_LOCATION: If this attribute is specified, \p data will be
* interpreted as a 32-bit integer, and \p dataSize must be 4. The result returned will be a GPU device
* id if all pages in the memory range have that GPU as their preferred location, or it will be CU_DEVICE_CPU
* if all pages in the memory range have the CPU as their preferred location, or it will be CU_DEVICE_INVALID
* if either all the pages don't have the same preferred location or some of the pages don't have a
* preferred location at all. Note that the actual location of the pages in the memory range at the time of
* the query may be different from the preferred location.
* - ::CU_MEM_RANGE_ATTRIBUTE_ACCESSED_BY: If this attribute is specified, \p data will be interpreted
* as an array of 32-bit integers, and \p dataSize must be a non-zero multiple of 4. The result returned
* will be a list of device ids that had ::CU_MEM_ADVISE_SET_ACCESSED_BY set for that entire memory range.
* If any device does not have that advice set for the entire memory range, that device will not be included.
* If \p data is larger than the number of devices that have that advice set for that memory range,
* CU_DEVICE_INVALID will be returned in all the extra space provided. For ex., if \p dataSize is 12
* (i.e. \p data has 3 elements) and only device 0 has the advice set, then the result returned will be
* { 0, CU_DEVICE_INVALID, CU_DEVICE_INVALID }. If \p data is smaller than the number of devices that have
* that advice set, then only as many devices will be returned as can fit in the array. There is no
* guarantee on which specific devices will be returned, however.
* - ::CU_MEM_RANGE_ATTRIBUTE_LAST_PREFETCH_LOCATION: If this attribute is specified, \p data will be
* interpreted as a 32-bit integer, and \p dataSize must be 4. The result returned will be the last location
* to which all pages in the memory range were prefetched explicitly via ::cuMemPrefetchAsync. This will either be
* a GPU id or CU_DEVICE_CPU depending on whether the last location for prefetch was a GPU or the CPU
* respectively. If any page in the memory range was never explicitly prefetched or if all pages were not
* prefetched to the same location, CU_DEVICE_INVALID will be returned. Note that this simply returns the
* last location that the application requested to prefetch the memory range to. It gives no indication as to
* whether the prefetch operation to that location has completed or even begun.
* - ::CU_MEM_RANGE_ATTRIBUTE_PREFERRED_LOCATION_TYPE: If this attribute is specified, \p data will be
* interpreted as a ::CUmemLocationType, and \p dataSize must be sizeof(CUmemLocationType). The ::CUmemLocationType returned will be
* ::CU_MEM_LOCATION_TYPE_DEVICE if all pages in the memory range have the same GPU as their preferred location, or ::CUmemLocationType
* will be ::CU_MEM_LOCATION_TYPE_HOST if all pages in the memory range have the CPU as their preferred location, or it will be ::CU_MEM_LOCATION_TYPE_HOST_NUMA
* if all the pages in the memory range have the same host NUMA node ID as their preferred location or it will be ::CU_MEM_LOCATION_TYPE_INVALID
* if either all the pages don't have the same preferred location or some of the pages don't have a preferred location at all.
* Note that the actual location type of the pages in the memory range at the time of the query may be different from the preferred location type.
* - ::CU_MEM_RANGE_ATTRIBUTE_PREFERRED_LOCATION_ID: If this attribute is specified, \p data will be
* interpreted as a 32-bit integer, and \p dataSize must be 4. If the ::CU_MEM_RANGE_ATTRIBUTE_PREFERRED_LOCATION_TYPE query for the same address range
* returns ::CU_MEM_LOCATION_TYPE_DEVICE, it will be a valid device ordinal or if it returns ::CU_MEM_LOCATION_TYPE_HOST_NUMA, it will be a valid host NUMA node ID
* or if it returns any other location type, the id should be ignored.
* - ::CU_MEM_RANGE_ATTRIBUTE_LAST_PREFETCH_LOCATION_TYPE: If this attribute is specified, \p data will be
* interpreted as a ::CUmemLocationType, and \p dataSize must be sizeof(CUmemLocationType). The result returned will be the last location
* to which all pages in the memory range were prefetched explicitly via ::cuMemPrefetchAsync. The ::CUmemLocationType returned
* will be ::CU_MEM_LOCATION_TYPE_DEVICE if the last prefetch location was a GPU or ::CU_MEM_LOCATION_TYPE_HOST if it was the CPU or ::CU_MEM_LOCATION_TYPE_HOST_NUMA if

* the stream active until all preceding host functions and stream callbacks
* have executed. Thus, for
* example, a callback might use global attached memory even if work has
* been added to another stream, if the work has been ordered behind the
* callback with an event.</li>
* <li>Completion of a callback does not cause a stream to become
* active except as described above. The callback stream will remain idle
* if no device work follows the callback, and will remain idle across
* consecutive callbacks without device work in between. Thus, for example,

/**
* \brief Attach memory to a stream asynchronously
*
* Enqueues an operation in \p hStream to specify stream association of
* \p length bytes of memory starting from \p dptr. This function is a
* stream-ordered operation, meaning that it is dependent on, and will
* only take effect when, previous work in stream has completed. Any
* previous association is automatically replaced.
*
* \p dptr must point to one of the following types of memories:
* - managed memory declared using the __managed__ keyword or allocated with
* ::cuMemAllocManaged.
* - a valid host-accessible region of system-allocated pageable memory. This
* type of memory may only be specified if the device associated with the
* stream reports a non-zero value for the device attribute
* ::CU_DEVICE_ATTRIBUTE_PAGEABLE_MEMORY_ACCESS.
*
* For managed allocations, \p length must be either zero or the entire
* allocation's size. Both indicate that the entire allocation's stream
* association is being changed. Currently, it is not possible to change stream
* association for a portion of a managed allocation.
*
* For pageable host allocations, \p length must be non-zero.
*
* The stream association is specified using \p flags which must be
* one of ::CUmemAttach_flags.
* If the ::CU_MEM_ATTACH_GLOBAL flag is specified, the memory can be accessed
* by any stream on any device.
* If the ::CU_MEM_ATTACH_HOST flag is specified, the program makes a guarantee
* that it won't access the memory on the device from any stream on a device that
* has a zero value for the device attribute ::CU_DEVICE_ATTRIBUTE_CONCURRENT_MANAGED_ACCESS.
* If the ::CU_MEM_ATTACH_SINGLE flag is specified and \p hStream is associated with
* a device that has a zero value for the device attribute ::CU_DEVICE_ATTRIBUTE_CONCURRENT_MANAGED_ACCESS,
* the program makes a guarantee that it will only access the memory on the device
* from \p hStream. It is illegal to attach singly to the NULL stream, because the
* NULL stream is a virtual global stream and not a specific stream. An error will
* be returned in this case.
*
* When memory is associated with a single stream, the Unified Memory system will
* allow CPU access to this memory region so long as all operations in \p hStream
* have completed, regardless of whether other streams are active. In effect,
* this constrains exclusive ownership of the managed memory region by
* an active GPU to per-stream activity instead of whole-GPU activity.
*
* Accessing memory on the device from streams that are not associated with
* it will produce undefined results. No error checking is performed by the
* Unified Memory system to ensure that kernels launched into other streams
* do not access this region.
*
* It is a program's responsibility to order calls to ::cuStreamAttachMemAsync
* via events, synchronization or other means to ensure legal access to memory
* at all times. Data visibility and coherency will be changed appropriately
* for all kernels which follow a stream-association change.
*
* If \p hStream is destroyed while data is associated with it, the association is
* removed and the association reverts to the default visibility of the allocation
* as specified at ::cuMemAllocManaged. For __managed__ variables, the default
* association is always ::CU_MEM_ATTACH_GLOBAL. Note that destroying a stream is an
* asynchronous operation, and as a result, the change to default association won't
* happen until all work in the stream has completed.

/**
* \brief Imports an external memory object
*
* Imports an externally allocated memory object and returns
* a handle to that in \p extMem_out.
*
* The properties of the handle being imported must be described in
* \p memHandleDesc. The ::CUDA_EXTERNAL_MEMORY_HANDLE_DESC structure
* is defined as follows:
*
* \code
typedef struct CUDA_EXTERNAL_MEMORY_HANDLE_DESC_st {
CUexternalMemoryHandleType type;
union {
int fd;
struct {
void *handle;
const void *name;
} win32;
const void *nvSciBufObject;
} handle;
unsigned long long size;
unsigned int flags;
} CUDA_EXTERNAL_MEMORY_HANDLE_DESC;
* \endcode
*
* where ::CUDA_EXTERNAL_MEMORY_HANDLE_DESC::type specifies the type
* of handle being imported. ::CUexternalMemoryHandleType is
* defined as:
*
* \code
typedef enum CUexternalMemoryHandleType_enum {
CU_EXTERNAL_MEMORY_HANDLE_TYPE_OPAQUE_FD = 1,
CU_EXTERNAL_MEMORY_HANDLE_TYPE_OPAQUE_WIN32 = 2,
CU_EXTERNAL_MEMORY_HANDLE_TYPE_OPAQUE_WIN32_KMT = 3,
CU_EXTERNAL_MEMORY_HANDLE_TYPE_D3D12_HEAP = 4,
CU_EXTERNAL_MEMORY_HANDLE_TYPE_D3D12_RESOURCE = 5,
CU_EXTERNAL_MEMORY_HANDLE_TYPE_D3D11_RESOURCE = 6,
CU_EXTERNAL_MEMORY_HANDLE_TYPE_D3D11_RESOURCE_KMT = 7,
CU_EXTERNAL_MEMORY_HANDLE_TYPE_NVSCIBUF = 8
} CUexternalMemoryHandleType;
* \endcode
*
* If ::CUDA_EXTERNAL_MEMORY_HANDLE_DESC::type is
* ::CU_EXTERNAL_MEMORY_HANDLE_TYPE_OPAQUE_FD, then
* ::CUDA_EXTERNAL_MEMORY_HANDLE_DESC::handle::fd must be a valid
* file descriptor referencing a memory object. Ownership of
* the file descriptor is transferred to the CUDA driver when the
* handle is imported successfully. Performing any operations on the
* file descriptor after it is imported results in undefined behavior.
*
* If ::CUDA_EXTERNAL_MEMORY_HANDLE_DESC::type is
* ::CU_EXTERNAL_MEMORY_HANDLE_TYPE_OPAQUE_WIN32, then exactly one
* of ::CUDA_EXTERNAL_MEMORY_HANDLE_DESC::handle::win32::handle and
* ::CUDA_EXTERNAL_MEMORY_HANDLE_DESC::handle::win32::name must not be
* NULL. If ::CUDA_EXTERNAL_MEMORY_HANDLE_DESC::handle::win32::handle
* is not NULL, then it must represent a valid shared NT handle that
* references a memory object. Ownership of this handle is
* not transferred to CUDA after the import operation, so the
* application must release the handle using the appropriate system
* call. If ::CUDA_EXTERNAL_MEMORY_HANDLE_DESC::handle::win32::name
* is not NULL, then it must point to a NULL-terminated array of
* UTF-16 characters that refers to a memory object.
*
* If ::CUDA_EXTERNAL_MEMORY_HANDLE_DESC::type is
* ::CU_EXTERNAL_MEMORY_HANDLE_TYPE_OPAQUE_WIN32_KMT, then
* ::CUDA_EXTERNAL_MEMORY_HANDLE_DESC::handle::win32::handle must
* be non-NULL and
* ::CUDA_EXTERNAL_MEMORY_HANDLE_DESC::handle::win32::name
* must be NULL. The handle specified must be a globally shared KMT
* handle. This handle does not hold a reference to the underlying
* object, and thus will be invalid when all references to the
* memory object are destroyed.
*
* If ::CUDA_EXTERNAL_MEMORY_HANDLE_DESC::type is
* ::CU_EXTERNAL_MEMORY_HANDLE_TYPE_D3D12_HEAP, then exactly one
* of ::CUDA_EXTERNAL_MEMORY_HANDLE_DESC::handle::win32::handle and
* ::CUDA_EXTERNAL_MEMORY_HANDLE_DESC::handle::win32::name must not be
* NULL. If ::CUDA_EXTERNAL_MEMORY_HANDLE_DESC::handle::win32::handle
* is not NULL, then it must represent a valid shared NT handle that
* is returned by ID3D12Device::CreateSharedHandle when referring to a
* ID3D12Heap object. This handle holds a reference to the underlying
* object. If ::CUDA_EXTERNAL_MEMORY_HANDLE_DESC::handle::win32::name
* is not NULL, then it must point to a NULL-terminated array of
* UTF-16 characters that refers to a ID3D12Heap object.
*
* If ::CUDA_EXTERNAL_MEMORY_HANDLE_DESC::type is
* ::CU_EXTERNAL_MEMORY_HANDLE_TYPE_D3D12_RESOURCE, then exactly one
* of ::CUDA_EXTERNAL_MEMORY_HANDLE_DESC::handle::win32::handle and
* ::CUDA_EXTERNAL_MEMORY_HANDLE_DESC::handle::win32::name must not be
* NULL. If ::CUDA_EXTERNAL_MEMORY_HANDLE_DESC::handle::win32::handle
* is not NULL, then it must represent a valid shared NT handle that
* is returned by ID3D12Device::CreateSharedHandle when referring to a
* ID3D12Resource object. This handle holds a reference to the
* underlying object. If
* ::CUDA_EXTERNAL_MEMORY_HANDLE_DESC::handle::win32::name
* is not NULL, then it must point to a NULL-terminated array of
* UTF-16 characters that refers to a ID3D12Resource object.
*
* If ::CUDA_EXTERNAL_MEMORY_HANDLE_DESC::type is
* ::CU_EXTERNAL_MEMORY_HANDLE_TYPE_D3D11_RESOURCE, then
* ::CUDA_EXTERNAL_MEMORY_HANDLE_DESC::handle::win32::handle must
* represent a valid shared NT handle that is returned by
* IDXGIResource1::CreateSharedHandle when referring to a
* ID3D11Resource object. If
* ::CUDA_EXTERNAL_MEMORY_HANDLE_DESC::handle::win32::name
* is not NULL, then it must point to a NULL-terminated array of
* UTF-16 characters that refers to a ID3D11Resource object.
*
* If ::CUDA_EXTERNAL_MEMORY_HANDLE_DESC::type is
* ::CU_EXTERNAL_MEMORY_HANDLE_TYPE_D3D11_RESOURCE_KMT, then
* ::CUDA_EXTERNAL_MEMORY_HANDLE_DESC::handle::win32::handle must
* represent a valid shared KMT handle that is returned by
* IDXGIResource::GetSharedHandle when referring to a
* ID3D11Resource object and
* ::CUDA_EXTERNAL_MEMORY_HANDLE_DESC::handle::win32::name
* must be NULL.
*
* If ::CUDA_EXTERNAL_MEMORY_HANDLE_DESC::type is
* ::CU_EXTERNAL_MEMORY_HANDLE_TYPE_NVSCIBUF, then
* ::CUDA_EXTERNAL_MEMORY_HANDLE_DESC::handle::nvSciBufObject must be non-NULL
* and reference a valid NvSciBuf object.
* If the NvSciBuf object imported into CUDA is also mapped by other drivers, then the
* application must use ::cuWaitExternalSemaphoresAsync or ::cuSignalExternalSemaphoresAsync
* as appropriate barriers to maintain coherence between CUDA and the other drivers.
* See ::CUDA_EXTERNAL_SEMAPHORE_SIGNAL_SKIP_NVSCIBUF_MEMSYNC and ::CUDA_EXTERNAL_SEMAPHORE_WAIT_SKIP_NVSCIBUF_MEMSYNC
* for memory synchronization.
*
*
* The size of the memory object must be specified in
* ::CUDA_EXTERNAL_MEMORY_HANDLE_DESC::size.
*
* Specifying the flag ::CUDA_EXTERNAL_MEMORY_DEDICATED in
* ::CUDA_EXTERNAL_MEMORY_HANDLE_DESC::flags indicates that the
* resource is a dedicated resource. The definition of what a
* dedicated resource is outside the scope of this extension.
* This flag must be set if ::CUDA_EXTERNAL_MEMORY_HANDLE_DESC::type
* is one of the following:
* ::CU_EXTERNAL_MEMORY_HANDLE_TYPE_D3D12_RESOURCE

* ::CUDA_EXTERNAL_SEMAPHORE_SIGNAL_PARAMS::params::fence::value.
*
* If the semaphore object is of the type ::CU_EXTERNAL_SEMAPHORE_HANDLE_TYPE_NVSCISYNC
* this API sets ::CUDA_EXTERNAL_SEMAPHORE_SIGNAL_PARAMS::params::nvSciSync::fence
* to a value that can be used by subsequent waiters of the same NvSciSync object
* to order operations with those currently submitted in \p stream. Such an update
* will overwrite previous contents of
* ::CUDA_EXTERNAL_SEMAPHORE_SIGNAL_PARAMS::params::nvSciSync::fence. By default,
* signaling such an external semaphore object causes appropriate memory synchronization
* operations to be performed over all external memory objects that are imported as
* ::CU_EXTERNAL_MEMORY_HANDLE_TYPE_NVSCIBUF. This ensures that any subsequent accesses
* made by other importers of the same set of NvSciBuf memory object(s) are coherent.
* These operations can be skipped by specifying the flag
* ::CUDA_EXTERNAL_SEMAPHORE_SIGNAL_SKIP_NVSCIBUF_MEMSYNC, which can be used as a
* performance optimization when data coherency is not required. But specifying this
* flag in scenarios where data coherency is required results in undefined behavior.
* Also, for semaphore object of the type ::CU_EXTERNAL_SEMAPHORE_HANDLE_TYPE_NVSCISYNC,
* if the NvSciSyncAttrList used to create the NvSciSyncObj had not set the flags in
* ::cuDeviceGetNvSciSyncAttributes to CUDA_NVSCISYNC_ATTR_SIGNAL, this API will return
* CUDA_ERROR_NOT_SUPPORTED.
* NvSciSyncFence associated with semaphore object of the type
* ::CU_EXTERNAL_SEMAPHORE_HANDLE_TYPE_NVSCISYNC can be deterministic. For this the
* NvSciSyncAttrList used to create the semaphore object must have value of
* NvSciSyncAttrKey_RequireDeterministicFences key set to true. Deterministic fences
* allow users to enqueue a wait over the semaphore object even before corresponding
* signal is enqueued. For such a semaphore object, CUDA guarantees that each signal
* operation will increment the fence value by '1'. Users are expected to track count
* of signals enqueued on the semaphore object and insert waits accordingly. When such
* a semaphore object is signaled from multiple streams, due to concurrent stream
* execution, it is possible that the order in which the semaphore gets signaled is
* indeterministic. This could lead to waiters of the semaphore getting unblocked
* incorrectly. Users are expected to handle such situations, either by not using the
* same semaphore object with deterministic fence support enabled in different streams
* or by adding explicit dependency amongst such streams so that the semaphore is
* signaled in order.
*
* If the semaphore object is any one of the following types:
* ::CU_EXTERNAL_SEMAPHORE_HANDLE_TYPE_D3D11_KEYED_MUTEX,

* depends on both the function and the device on which the function is
* currently loaded.
* - ::CU_FUNC_ATTRIBUTE_SHARED_SIZE_BYTES: The size in bytes of

* - ::CU_FUNC_ATTRIBUTE_CONST_SIZE_BYTES: The size in bytes of user-allocated

* - ::CU_FUNC_ATTRIBUTE_LOCAL_SIZE_BYTES: The size in bytes of local memory
* used by each thread of this function.
* - ::CU_FUNC_ATTRIBUTE_NUM_REGS: The number of registers used by each thread
* of this function.
* - ::CU_FUNC_ATTRIBUTE_PTX_VERSION: The PTX virtual architecture version for
* which the function was compiled. This value is the major PTX version * 10
* + the minor PTX version, so a PTX version 1.3 function would return the
* value 13. Note that this may return the undefined value of 0 for cubins
* compiled prior to CUDA 3.0.

* version * 10 + the minor binary version, so a binary version 1.3 function
* would return the value 13. Note that this will return a value of 10 for
* legacy cubins that do not have a properly-encoded binary architecture
* version.
* - ::CU_FUNC_CACHE_MODE_CA: The attribute to indicate whether the function has
* been compiled with user specified option "-Xptxas --dlcm=ca" set .
* - ::CU_FUNC_ATTRIBUTE_MAX_DYNAMIC_SHARED_SIZE_BYTES: The maximum size in bytes of
* dynamically-allocated shared memory.
* - ::CU_FUNC_ATTRIBUTE_PREFERRED_SHARED_MEMORY_CARVEOUT: Preferred shared memory-L1
* cache split ratio in percent of total shared memory.
* - ::CU_FUNC_ATTRIBUTE_CLUSTER_SIZE_MUST_BE_SET: If this attribute is set, the

* - ::CU_FUNC_ATTRIBUTE_REQUIRED_CLUSTER_DEPTH: The required cluster depth in
* blocks.
* - ::CU_FUNC_ATTRIBUTE_NON_PORTABLE_CLUSTER_SIZE_ALLOWED: Indicates whether
* the function can be launched with non-portable cluster size. 1 is allowed,
* 0 is disallowed. A non-portable cluster size may only function on the
* specific SKUs the program is tested on. The launch might fail if the
* program is run on a different hardware platform. CUDA API provides
* cudaOccupancyMaxActiveClusters to assist with checking whether the desired
* size can be launched on the current device. A portable cluster size is

*
* \p sharedMemBytes sets the amount of dynamic shared memory that will be

*
* Kernel parameters to \p f can be specified in one of two ways:

* has N parameters, then \p kernelParams needs to be an array of N
* pointers. Each of \p kernelParams[0] through \p kernelParams[N-1]
* must point to a region of memory from which the actual kernel
* parameter will be copied. The number of kernel parameters and their
* offsets and sizes do not need to be specified as that information is
* retrieved directly from the kernel's image.
*
* 2) Kernel parameters can also be packaged by the application into
* a single buffer that is passed in via the \p extra parameter.
* This places the burden on the application of knowing each kernel
* parameter's size and alignment/padding within the buffer. Here is
* an example of using the \p extra parameter in this manner:

CU_LAUNCH_PARAM_BUFFER_SIZE, &argBufferSize,
CU_LAUNCH_PARAM_END
};
status = cuLaunchKernel(f, gx, gy, gz, bx, by, bz, sh, s, NULL, config);
* \endcode
*
* The \p extra parameter exists to allow ::cuLaunchKernel to take
* additional less commonly used arguments. \p extra specifies a list of
* names of extra settings and their corresponding values. Each extra
* setting name is immediately followed by the corresponding value. The
* list must be terminated with either NULL or ::CU_LAUNCH_PARAM_END.
*
* - ::CU_LAUNCH_PARAM_END, which indicates the end of the \p extra
* array;
* - ::CU_LAUNCH_PARAM_BUFFER_POINTER, which specifies that the next
* value in \p extra will be a pointer to a buffer containing all
* the kernel parameters for launching kernel \p f;
* - ::CU_LAUNCH_PARAM_BUFFER_SIZE, which specifies that the next
* value in \p extra will be a pointer to a size_t containing the
* size of the buffer specified with ::CU_LAUNCH_PARAM_BUFFER_POINTER;
*

/**
* \brief Launches a CUDA function ::CUfunction or a CUDA kernel ::CUkernel with launch-time configuration
*
* Invokes the function ::CUfunction or the kernel ::CUkernel \p f with the specified launch-time configuration
* \p config.
*
* The ::CUlaunchConfig structure is defined as:
*
* \code
* typedef struct CUlaunchConfig_st {
* unsigned int gridDimX;
* unsigned int gridDimY;
* unsigned int gridDimZ;
* unsigned int blockDimX;
* unsigned int blockDimY;
* unsigned int blockDimZ;
* unsigned int sharedMemBytes;
* CUstream hStream;
* CUlaunchAttribute *attrs;
* unsigned int numAttrs;
* } CUlaunchConfig;
* \endcode
*
* where:
* - ::CUlaunchConfig::gridDimX is the width of the grid in blocks.
* - ::CUlaunchConfig::gridDimY is the height of the grid in blocks.
* - ::CUlaunchConfig::gridDimZ is the depth of the grid in blocks.
* - ::CUlaunchConfig::blockDimX is the X dimension of each thread block.
* - ::CUlaunchConfig::blockDimX is the Y dimension of each thread block.
* - ::CUlaunchConfig::blockDimZ is the Z dimension of each thread block.
* - ::CUlaunchConfig::sharedMemBytes is the dynamic shared-memory size per
* thread block in bytes.
* - ::CUlaunchConfig::hStream is the handle to the stream to perform the launch
* in. The CUDA context associated with this stream must match that associated
* with function f.
* - ::CUlaunchConfig::attrs is an array of ::CUlaunchConfig::numAttrs
* continguous ::CUlaunchAttribute elements. The value of this pointer is not
* considered if ::CUlaunchConfig::numAttrs is zero. However, in that case, it
* is recommended to set the pointer to NULL.
* - ::CUlaunchConfig::numAttrs is the number of attributes populating the
* first ::CUlaunchConfig::numAttrs positions of the ::CUlaunchConfig::attrs
* array.
*
* Launch-time configuration is specified by adding entries to
* ::CUlaunchConfig::attrs. Each entry is an attribute ID and a corresponding
* attribute value.
*
* The ::CUlaunchAttribute structure is defined as:
* \code
* typedef struct CUlaunchAttribute_st {
* CUlaunchAttributeID id;
* CUlaunchAttributeValue value;
* } CUlaunchAttribute;
* \endcode
* where:
* - ::CUlaunchAttribute::id is a unique enum identifying the attribute.
* - ::CUlaunchAttribute::value is a union that hold the attribute value.
*
* An example of using the \p config parameter:
* \code
* CUlaunchAttribute coopAttr = {.id = CU_LAUNCH_ATTRIBUTE_COOPERATIVE,
* .value = 1};
* CUlaunchConfig config = {... // set block and grid dimensions
* .attrs = &coopAttr,
* .numAttrs = 1};
*
* cuLaunchKernelEx(&config, kernel, NULL, NULL);
* \endcode
*
* The ::CUlaunchAttributeID enum is defined as:
* \code
* typedef enum CUlaunchAttributeID_enum {
* CU_LAUNCH_ATTRIBUTE_IGNORE = 0,
* CU_LAUNCH_ATTRIBUTE_ACCESS_POLICY_WINDOW = 1,
* CU_LAUNCH_ATTRIBUTE_COOPERATIVE = 2,
* CU_LAUNCH_ATTRIBUTE_SYNCHRONIZATION_POLICY = 3,
* CU_LAUNCH_ATTRIBUTE_CLUSTER_DIMENSION = 4,
* CU_LAUNCH_ATTRIBUTE_CLUSTER_SCHEDULING_POLICY_PREFERENCE = 5,
* CU_LAUNCH_ATTRIBUTE_PROGRAMMATIC_STREAM_SERIALIZATION = 6,
* CU_LAUNCH_ATTRIBUTE_PROGRAMMATIC_EVENT = 7,
* CU_LAUNCH_ATTRIBUTE_PRIORITY = 8,
* CU_LAUNCH_ATTRIBUTE_MEM_SYNC_DOMAIN_MAP = 9,
* CU_LAUNCH_ATTRIBUTE_MEM_SYNC_DOMAIN = 10,
* CU_LAUNCH_ATTRIBUTE_LAUNCH_COMPLETION_EVENT = 12,
* CU_LAUNCH_ATTRIBUTE_DEVICE_UPDATABLE_KERNEL_NODE = 13,
* } CUlaunchAttributeID;
* \endcode
*
* and the corresponding ::CUlaunchAttributeValue union as :
* \code
* typedef union CUlaunchAttributeValue_union {
* CUaccessPolicyWindow accessPolicyWindow;
* int cooperative;
* CUsynchronizationPolicy syncPolicy;
* struct {
* unsigned int x;
* unsigned int y;
* unsigned int z;
* } clusterDim;
* CUclusterSchedulingPolicy clusterSchedulingPolicyPreference;
* int programmaticStreamSerializationAllowed;
* struct {
* CUevent event;
* int flags;
* int triggerAtBlockStart;
* } programmaticEvent;
* int priority;
* CUlaunchMemSyncDomainMap memSyncDomainMap;
* CUlaunchMemSyncDomain memSyncDomain;
* struct {
* CUevent event;
* int flags;
* } launchCompletionEvent;
* struct {
* int deviceUpdatable;
* CUgraphDeviceNode devNode;
* } deviceUpdatableKernelNode;
* } CUlaunchAttributeValue;
* \endcode
*
* Setting ::CU_LAUNCH_ATTRIBUTE_COOPERATIVE to a non-zero value causes the
* kernel launch to be a cooperative launch, with exactly the same usage and
* semantics of ::cuLaunchCooperativeKernel.
*
* Setting ::CU_LAUNCH_ATTRIBUTE_PROGRAMMATIC_STREAM_SERIALIZATION to a non-zero
* values causes the kernel to use programmatic means to resolve its stream
* dependency -- enabling the CUDA runtime to opportunistically allow the grid's
* execution to overlap with the previous kernel in the stream, if that kernel
* requests the overlap.
*
* ::CU_LAUNCH_ATTRIBUTE_PROGRAMMATIC_EVENT records an event along with the
* kernel launch. Event recorded through this launch attribute is guaranteed to
* only trigger after all block in the associated kernel trigger the event. A
* block can trigger the event through PTX launchdep.release or CUDA builtin
* function cudaTriggerProgrammaticLaunchCompletion(). A trigger can also be
* inserted at the beginning of each block's execution if triggerAtBlockStart is
* set to non-0. Note that dependents (including the CPU thread calling
* cuEventSynchronize()) are not guaranteed to observe the release precisely
* when it is released. For example, cuEventSynchronize() may only observe the
* event trigger long after the associated kernel has completed. This recording
* type is primarily meant for establishing programmatic dependency between
* device tasks. The event supplied must not be an interprocess or interop
* event. The event must disable timing (i.e. created with
* ::CU_EVENT_DISABLE_TIMING flag set).
*
* ::CU_LAUNCH_ATTRIBUTE_LAUNCH_COMPLETION_EVENT records an event along with
* the kernel launch. Nominally, the event is triggered once all blocks of the
* kernel have begun execution. Currently this is a best effort. If a kernel B
* has a launch completion dependency on a kernel A, B may wait until A is
* complete. Alternatively, blocks of B may begin before all blocks of A have
* begun, for example:
*
* - If B can claim execution resources unavaiable to A, for example if they
* run on different GPUs.
* - If B is a higher priority than A.
*
* Exercise caution if such an ordering inversion could lead to deadlock. The
* event supplied must not be an interprocess or interop event. The event must
* disable timing (i.e. must be created with the ::CU_EVENT_DISABLE_TIMING flag
* set).
*
* Setting ::CU_LAUNCH_ATTRIBUTE_DEVICE_UPDATABLE_KERNEL_NODE to 1
* on a captured launch causes the resulting kernel node to be device-updatable.
* This attribute is specific to graphs, and passing it to a launch in a
* non-capturing stream results in an error. Passing a value other than 0 or 1 is
* not allowed.
*
* On success, a handle will be returned via
* ::CUlaunchAttributeValue::deviceUpdatableKernelNode::devNode which can be passed
* to the various device-side update functions to update the node's kernel parameters
* from within another kernel. For more information on the types of device updates
* that can be made, as well as the relevant limitations thereof, see
* ::cudaGraphKernelNodeUpdatesApply.
*
* Kernel nodes which are device-updatable have additional restrictions compared to regular
* kernel nodes. Firstly, device-updatable nodes cannot be removed from their graph via
* ::cuGraphDestroyNode. Additionally, once opted-in to this functionality, a node cannot
* opt out, and any attempt to set the attribute to 0 will result in an error. Graphs
* containing one or more device-updatable node also do not allow multiple instantiation.
*
*
* The effect of other attributes is consistent with their effect when set via
* persistent APIs.

* - ::CU_LAUNCH_ATTRIBUTE_ACCESS_POLICY_WINDOW

/**
* \brief Enqueues a host function call in a stream
*
* Enqueues a host function to run in a stream. The function will be called
* after currently enqueued work and will block work added after it.
*
* The host function must not make any CUDA API calls. Attempting to use a
* CUDA API may result in ::CUDA_ERROR_NOT_PERMITTED, but this is not required.
* The host function must not perform any synchronization that may depend on
* outstanding CUDA work not mandated to run earlier. Host functions without a
* mandated order (such as in independent streams) execute in undefined order
* and may be serialized.
*
* For the purposes of Unified Memory, execution makes a number of guarantees:
* <ul>
* <li>The stream is considered idle for the duration of the function's
* execution. Thus, for example, the function may always use memory attached
* to the stream it was enqueued in.</li>
* <li>The start of execution of the function has the same effect as
* synchronizing an event recorded in the same stream immediately prior to
* the function. It thus synchronizes streams which have been "joined"
* prior to the function.</li>
* <li>Adding device work to any stream does not have the effect of making
* the stream active until all preceding host functions and stream callbacks
* have executed. Thus, for
* example, a function might use global attached memory even if work has
* been added to another stream, if the work has been ordered behind the
* function call with an event.</li>
* <li>Completion of the function does not cause a stream to become
* active except as described above. The stream will remain idle
* if no device work follows the function, and will remain idle across
* consecutive host functions or stream callbacks without device work in
* between. Thus, for example,
* stream synchronization can be done by signaling from a host function at the
* end of the stream.</li>

* unsigned int gridDimZ;
* unsigned int blockDimX;

*
* When the graph is launched, the node will invoke kernel \p func on a (\p gridDimX x
* \p gridDimY x \p gridDimZ) grid of blocks. Each block contains
* (\p blockDimX x \p blockDimY x \p blockDimZ) threads.
*
* \p sharedMemBytes sets the amount of dynamic shared memory that will be
* available to each thread block.
*
* Kernel parameters to \p func can be specified in one of two ways:
*
* 1) Kernel parameters can be specified via \p kernelParams. If the kernel has N
* parameters, then \p kernelParams needs to be an array of N pointers. Each pointer,
* from \p kernelParams[0] to \p kernelParams[N-1], points to the region of memory from which the actual
* parameter will be copied. The number of kernel parameters and their offsets and sizes do not need
* to be specified as that information is retrieved directly from the kernel's image.
*
* 2) Kernel parameters for non-cooperative kernels can also be packaged by the application into a single
* buffer that is passed in via \p extra. This places the burden on the application of knowing each
* kernel parameter's size and alignment/padding within the buffer. The \p extra parameter exists
* to allow this function to take additional less commonly used arguments. \p extra specifies
* a list of names of extra settings and their corresponding values. Each extra setting name is
* immediately followed by the corresponding value. The list must be terminated with either NULL or
* CU_LAUNCH_PARAM_END.
*
* - ::CU_LAUNCH_PARAM_END, which indicates the end of the \p extra
* array;
* - ::CU_LAUNCH_PARAM_BUFFER_POINTER, which specifies that the next
* value in \p extra will be a pointer to a buffer
* containing all the kernel parameters for launching kernel
* \p func;
* - ::CU_LAUNCH_PARAM_BUFFER_SIZE, which specifies that the next
* value in \p extra will be a pointer to a size_t
* containing the size of the buffer specified with
* ::CU_LAUNCH_PARAM_BUFFER_POINTER;
*
* The error ::CUDA_ERROR_INVALID_VALUE will be returned if kernel parameters are specified with both
* \p kernelParams and \p extra (i.e. both \p kernelParams and \p extra are non-NULL).
* ::CUDA_ERROR_INVALID_VALUE will be returned if \p extra is used for a cooperative kernel.
*

*
* When ::cuGraphAddMemAllocNode creates an allocation node, it returns the address of the allocation in
* \p nodeParams.dptr. The allocation's address remains fixed across instantiations and launches.
*
* If the allocation is freed in the same graph, by creating a free node using ::cuGraphAddMemFreeNode,
* the allocation can be accessed by nodes ordered after the allocation node but before the free node.
* These allocations cannot be freed outside the owning graph, and they can only be freed once in the
* owning graph.
*
* If the allocation is not freed in the same graph, then it can be accessed not only by nodes in the
* graph which are ordered after the allocation node, but also by stream operations ordered after the
* graph's execution but before the allocation is freed.
*
* Allocations which are not freed in the same graph can be freed by:
* - passing the allocation to ::cuMemFreeAsync or ::cuMemFree;
* - launching a graph with a free node for that allocation; or
* - specifying ::CUDA_GRAPH_INSTANTIATE_FLAG_AUTO_FREE_ON_LAUNCH during instantiation, which makes
* each launch behave as though it called ::cuMemFreeAsync for every unfreed allocation.
*
* It is not possible to free an allocation in both the owning graph and another graph. If the allocation
* is freed in the same graph, a free node cannot be added to another graph. If the allocation is freed
* in another graph, a free node can no longer be added to the owning graph.
*
* The following restrictions apply to graphs which contain allocation and/or memory free nodes:
* - Nodes and edges of the graph cannot be deleted.
* - The graph cannot be used in a child node.
* - Only one instantiation of the graph may exist at any point in time.
* - The graph cannot be cloned.

* Updates the node parameters in the instantiated graph specified by \p hGraphExec with the

*
* Limitations:
*
* - Kernel nodes:
* - The owning context of the function cannot change.
* - A node whose function originally did not use CUDA dynamic parallelism cannot be updated
* to a function which uses CDP.
* - A node whose function originally did not make device-side update calls cannot be updated
* to a function which makes device-side update calls.
* - A cooperative node cannot be updated to a non-cooperative node, and vice-versa.
* - If the graph was instantiated with CUDA_GRAPH_INSTANTIATE_FLAG_USE_NODE_PRIORITY, the
* priority attribute cannot change. Equality is checked on the originally requested
* priority values, before they are clamped to the device's supported range.
* - If \p hGraphExec was not instantiated for device launch, a node whose function originally
* did not use device-side cudaGraphLaunch() cannot be updated to a function which uses
* device-side cudaGraphLaunch() unless the node resides on the same context as nodes which
* contained such calls at instantiate-time. If no such calls were present at instantiation,
* these updates cannot be performed at all.
* - Neither \p hGraph nor \p hGraphExec may contain device-updatable kernel nodes.
* - Memset and memcpy nodes:
* - The CUDA device(s) to which the operand(s) was allocated/mapped cannot change.
* - The source/destination memory must be allocated from the same contexts as the original
* source/destination memory.
* - Only 1D memsets can be changed.
* - Additional memcpy node restrictions:
* - Changing either the source or destination memory type(i.e. CU_MEMORYTYPE_DEVICE,
* CU_MEMORYTYPE_ARRAY, etc.) is not supported.
* - External semaphore wait nodes and record nodes:
* - Changing the number of semaphores is not supported.
* - Conditional nodes:
* - Changing node parameters is not supported.
* - Changeing parameters of nodes within the conditional body graph is subject to the rules above.
* - Conditional handle flags and default values are updated as part of the graph update.
*
* Note: The API may add further restrictions in future releases. The return code should always be checked.
*
* cuGraphExecUpdate sets the result member of \p resultInfo to CU_GRAPH_EXEC_UPDATE_ERROR_TOPOLOGY_CHANGED
* under the following conditions:
* - The count of nodes directly in \p hGraphExec and \p hGraph differ, in which case resultInfo->errorNode
* is set to NULL.
* - \p hGraph has more exit nodes than \p hGraph, in which case resultInfo->errorNode is set to one of
* the exit nodes in hGraph.
* - A node in \p hGraph has a different number of dependencies than the node from \p hGraphExec it is paired with,
* in which case resultInfo->errorNode is set to the node from \p hGraph.
* - A node in \p hGraph has a dependency that does not match with the corresponding dependency of the paired node
* from \p hGraphExec. resultInfo->errorNode will be set to the node from \p hGraph. resultInfo->errorFromNode
* will be set to the mismatched dependency. The dependencies are paired based on edge order and a dependency
* does not match when the nodes are already paired based on other edges examined in the graph.
*
* cuGraphExecUpdate sets the result member of \p resultInfo to:
* - CU_GRAPH_EXEC_UPDATE_ERROR if passed an invalid value.
* - CU_GRAPH_EXEC_UPDATE_ERROR_TOPOLOGY_CHANGED if the graph topology changed
* - CU_GRAPH_EXEC_UPDATE_ERROR_NODE_TYPE_CHANGED if the type of a node changed, in which case
* \p hErrorNode_out is set to the node from \p hGraph.
* - CU_GRAPH_EXEC_UPDATE_ERROR_UNSUPPORTED_FUNCTION_CHANGE if the function changed in an unsupported
* way(see note above), in which case \p hErrorNode_out is set to the node from \p hGraph
* - CU_GRAPH_EXEC_UPDATE_ERROR_PARAMETERS_CHANGED if any parameters to a node changed in a way
* that is not supported, in which case \p hErrorNode_out is set to the node from \p hGraph.
* - CU_GRAPH_EXEC_UPDATE_ERROR_ATTRIBUTES_CHANGED if any attributes of a node changed in a way
* that is not supported, in which case \p hErrorNode_out is set to the node from \p hGraph.
* - CU_GRAPH_EXEC_UPDATE_ERROR_NOT_SUPPORTED if something about a node is unsupported, like
* the node's type or configuration, in which case \p hErrorNode_out is set to the node from \p hGraph
*
* If the update fails for a reason not listed above, the result member of \p resultInfo will be set
* to CU_GRAPH_EXEC_UPDATE_ERROR. If the update succeeds, the result member will be set to CU_GRAPH_EXEC_UPDATE_SUCCESS.

*
* - ::CUDA_TEXTURE_DESC::flags can be any combination of the following:
* - ::CU_TRSF_READ_AS_INTEGER, which suppresses the default behavior of
* having the texture promote integer data to floating point data in the
* range [0, 1]. Note that texture with 32-bit integer format would not be
* promoted, regardless of whether or not this flag is specified.
* - ::CU_TRSF_NORMALIZED_COORDINATES, which suppresses the default behavior
* of having the texture coordinates range from [0, Dim) where Dim is the
* width or height of the CUDA array. Instead, the texture coordinates
* [0, 1.0) reference the entire breadth of the array dimension; Note that
* for CUDA mipmapped arrays, this flag has to be set.
* - ::CU_TRSF_DISABLE_TRILINEAR_OPTIMIZATION, which disables any trilinear
* filtering optimizations. Trilinear optimizations improve texture filtering
* performance by allowing bilinear filtering on textures in scenarios where
* it can closely approximate the expected results.
* - ::CU_TRSF_SEAMLESS_CUBEMAP, which enables seamless cube map filtering.
* This flag can only be specified if the underlying resource is a CUDA array
* or a CUDA mipmapped array that was created with the flag ::CUDA_ARRAY3D_CUBEMAP.

* will be applied for all dimensions. If the ::CUDA_TEXTURE_DESC::filterMode is
* set to ::CU_TR_FILTER_MODE_LINEAR seamless cube map filtering will be performed
* when sampling along the cube face borders.
*
* - ::CUDA_TEXTURE_DESC::maxAnisotropy specifies the maximum anisotropy ratio to be used when doing anisotropic filtering. This value will be
* clamped to the range [1,16].
*
* - ::CUDA_TEXTURE_DESC::mipmapFilterMode specifies the filter mode when the calculated mipmap level lies between two defined mipmap levels.
*
* - ::CUDA_TEXTURE_DESC::mipmapLevelBias specifies the offset to be applied to the calculated mipmap level.
*
* - ::CUDA_TEXTURE_DESC::minMipmapLevelClamp specifies the lower end of the mipmap level range to clamp access to.
*
* - ::CUDA_TEXTURE_DESC::maxMipmapLevelClamp specifies the upper end of the mipmap level range to clamp access to.

* \endcode
* where:
* - ::CUDA_RESOURCE_VIEW_DESC::format specifies how the data contained in the CUDA array or CUDA mipmapped array should
* be interpreted. Note that this can incur a change in size of the texture data. If the resource view format is a block
* compressed format, then the underlying CUDA array or CUDA mipmapped array has to have a base of format ::CU_AD_FORMAT_UNSIGNED_INT32.
* with 2 or 4 channels, depending on the block compressed format. For ex., BC1 and BC4 require the underlying CUDA array to have
* a format of ::CU_AD_FORMAT_UNSIGNED_INT32 with 2 channels. The other BC formats require the underlying resource to have the same base
* format but with 4 channels.
*
* - ::CUDA_RESOURCE_VIEW_DESC::width specifies the new width of the texture data. If the resource view format is a block
* compressed format, this value has to be 4 times the original width of the resource. For non block compressed formats,
* this value has to be equal to that of the original resource.
*
* - ::CUDA_RESOURCE_VIEW_DESC::height specifies the new height of the texture data. If the resource view format is a block
* compressed format, this value has to be 4 times the original height of the resource. For non block compressed formats,
* this value has to be equal to that of the original resource.
*
* - ::CUDA_RESOURCE_VIEW_DESC::depth specifies the new depth of the texture data. This value has to be equal to that of the
* original resource.
*
* - ::CUDA_RESOURCE_VIEW_DESC::firstMipmapLevel specifies the most detailed mipmap level. This will be the new mipmap level zero.
* For non-mipmapped resources, this value has to be zero.::CUDA_TEXTURE_DESC::minMipmapLevelClamp and ::CUDA_TEXTURE_DESC::maxMipmapLevelClamp
* will be relative to this value. For ex., if the firstMipmapLevel is set to 2, and a minMipmapLevelClamp of 1.2 is specified,
* then the actual minimum mipmap level clamp will be 3.2.
*
* - ::CUDA_RESOURCE_VIEW_DESC::lastMipmapLevel specifies the least detailed mipmap level. For non-mipmapped resources, this value
* has to be zero.
*
* - ::CUDA_RESOURCE_VIEW_DESC::firstLayer specifies the first layer index for layered textures. This will be the new layer zero.
* For non-layered resources, this value has to be zero.
*
* - ::CUDA_RESOURCE_VIEW_DESC::lastLayer specifies the last layer index for layered textures. For non-layered resources,

* should be specified as 11020. For a requested driver symbol, if the specified
* CUDA version is greater than or equal to the CUDA version in which the driver symbol
* was introduced, this API will return the function pointer to the corresponding
* versioned function.
*
* The pointer returned by the API should be cast to a function pointer matching the

* typedef can be picked up from the corresponding typedefs header file. For example,
* cudaTypedefs.h consists of function pointer typedefs for driver APIs defined in cuda.h.
*
* The API will return ::CUDA_SUCCESS and set the returned \p pfn to NULL if the
* requested driver function is not supported on the platform, no ABI
* compatible driver function exists for the specified \p cudaVersion or if the
* driver symbol is invalid.
*
* It will also set the optional \p symbolStatus to one of the values in

* on input arguments and \p pfn is valid
* - ::CU_GET_PROC_ADDRESS_SYMBOL_NOT_FOUND - The requested symbol was not found
* - ::CU_GET_PROC_ADDRESS_VERSION_NOT_SUFFICIENT - The requested symbol was found but is
* not supported by cudaVersion specified
*
* The requested flags can be:
* - ::CU_GET_PROC_ADDRESS_DEFAULT: This is the default mode. This is equivalent to
* ::CU_GET_PROC_ADDRESS_PER_THREAD_DEFAULT_STREAM if the code is compiled with
* --default-stream per-thread compilation flag or the macro CUDA_API_PER_THREAD_DEFAULT_STREAM
* is defined; ::CU_GET_PROC_ADDRESS_LEGACY_STREAM otherwise.
* - ::CU_GET_PROC_ADDRESS_LEGACY_STREAM: This will enable the search for all driver symbols
* that match the requested driver symbol name except the corresponding per-thread versions.
* - ::CU_GET_PROC_ADDRESS_PER_THREAD_DEFAULT_STREAM: This will enable the search for all
* driver symbols that match the requested driver symbol name including the per-thread
* versions. If a per-thread version is not found, the API will return the legacy version
* of the driver function.
*
* \param symbol - The base name of the driver API function to look for. As an example,
* for the driver API ::cuMemAlloc_v2, \p symbol would be cuMemAlloc and
* \p cudaVersion would be the ABI compatible CUDA version for the _v2 variant.
* \param pfn - Location to return the function pointer to the requested driver function

*
* ___MANBRIEF___ Driver level API for creation and manipulation of green contexts
* (___CURRENT_FILE___) ___ENDMANBRIEF___
*
* This section describes the APIs for creation and manipulation of green contexts in the CUDA
* driver. Green contexts are a lightweight alternative to traditional contexts, with the ability
* to pass in a set of resources that they should be initialized with. This allows the developer to
* represent distinct spatial partitions of the GPU, provision resources for them, and target them
* via the same programming model that CUDA exposes (streams, kernel launches, etc.).
*
* There are 4 main steps to using these new set of APIs.
* - (1) Start with an initial set of resources, for example via ::cuDeviceGetDevResource. Only SM type is supported today.
* - (2) Partition this set of resources by providing them as input to a partition API, for example: ::cuDevSmResourceSplitByCount.
* - (3) Finalize the specification of resources by creating a descriptor via ::cuDevResourceGenerateDesc.
* - (4) Provision the resources and create a green context via ::cuGreenCtxCreate.
*
* For \p CU_DEV_RESOURCE_TYPE_SM, the partitions created have minimum SM count requirements, often rounding up and aligning the
* minCount provided to ::cuDevSmResourceSplitByCount. The following is a guideline for each architecture
* and may be subject to change:
* - On Compute Architecture 6.X: The minimum count is 1 SM.
* - On Compute Architecture 7.X: The minimum count is 2 SMs and must be a multiple of 2.
* - On Compute Architecture 8.X: The minimum count is 4 SMs and must be a multiple of 2.
* - On Compute Architecture 9.0+: The minimum count is 8 SMs and must be a multiple of 8.
*
* In the future, flags can be provided to tradeoff functional and performance characteristics versus finer grained SM partitions.
*
* Even if the green contexts have disjoint SM partitions, it is not guaranteed that the kernels launched
* in them will run concurrently or have forward progress guarantees. This is due to other resources (like HW connections,
* see ::CUDA_DEVICE_MAX_CONNECTIONS) that could cause a dependency. Additionally, in certain scenarios,
* it is possible for the workload to run on more SMs than was provisioned (but never less).
* The following are two scenarios which can exhibit this behavior:
* - On Volta+ MPS: When \p CUDA_MPS_ACTIVE_THREAD_PERCENTAGE is used,
* the set of SMs that are used for running kernels can be scaled up to the value of SMs used for the MPS client.
* - On Compute Architecture 9.x: When a module with dynamic parallelism (CDP) is loaded, all future
* kernels running under green contexts may use and share an additional set of 2 SMs.

* the API will overwrite \p nbGroups with the amount actually created. The groups are written to the array in \p result.
* \p nbGroups can be less than the total amount if a smaller number of groups is needed.
*
* This API is used to spatially partition the input resource. The input resource needs to come from one of

* A limitation of the API is that the output results cannot be split again without
* first creating a descriptor and a green context with that descriptor.
*
* When creating the groups, the API will take into account the performance and functional characteristics of the

* than purely dividing the total SM count by the \p minCount due to cluster requirements or
* alignment and granularity requirements for the minCount.
*
* The \p remainder set, might not have the same functional or performance guarantees as the groups in \p result.
* Its use should be carefully planned and future partitions of the \p remainder set are discouraged.
*
* A successful API call must either have:
* - A valid array of \p result pointers of size passed in \p nbGroups, with \p Input of type \p CU_DEV_RESOURCE_TYPE_SM.
* Value of \p minCount must be between 0 and the SM count specified in \p input. \p remaining and \p useFlags are optional.
* - NULL passed in for \p result, with a valid integer pointer in \p nbGroups and \p Input of type \p CU_DEV_RESOURCE_TYPE_SM.
* Value of \p minCount must be between 0 and the SM count specified in \p input.
* This queries the number of groups that would be created by the API.
*
* Note: The API is not supported on 32-bit platforms.
*
* \param result - Output array of \p CUdevResource resources. Can be NULL to query the number of groups.
