# AMD CLR - Compute Language Runtimes
AMD CLR (Compute Language Runtime) contains source codes for AMD's compute languages runtimes: `HIP` and `OpenCL™`.
## Project Organisation
- `hipamd` - contains implementation of `HIP` language on AMD platform. It is hosted at [ROCm/clr/hipamd](https://github.com/ROCm/clr/tree/develop/hipamd)
- `opencl` - contains implementation of [OpenCL™](https://www.khronos.org/opencl/) on AMD platform. Now it is hosted at [ROCm/clr/opencl](https://github.com/ROCm/clr/tree/develop/opencl)
- `rocclr` - contains compute runtime used in `HIP` and `OpenCL™`. This is hosted at [ROCm/clr/rocclr](https://github.com/ROCm/clr/tree/develop/rocclr)
## How to build/install
### Prerequisites
Please refer to Quick Start Guide in [ROCm Docs](https://rocm.docs.amd.com/projects/install-on-linux/en/latest/tutorial/quick-start.html).
Building clr requires `rocm-hip-libraries` meta package, which provides the pre-requisites for clr.
If you need to build static clr library, `rocm-llvm-dev` package should be installed which has support for compilation of the static library.
### Linux
- Clone this repository
```
cd clr && mkdir build && cd build
```
- For HIP:
`cmake .. -DCLR_BUILD_HIP=ON -DHIP_COMMON_DIR=$HIP_COMMON_DIR`
`HIP_COMMON_DIR` points to [HIP](https://github.com/ROCm/HIP)
- For OpenCL™:
`cmake .. -DCLR_BUILD_OCL=ON`
- Build and install
```
make
make install
```
Users can also build `OCL` and `HIP` at the same time by passing `-DCLR_BUILD_HIP=ON -DCLR_BUILD_OCL=ON` to configure command.
HIP/CLR can be built as a static library, users need to add more options in `cmake` command,
`-DBUILD_SHARED_LIBS=OFF` and `-DCMAKE_PREFIX_PATH="/opt/rocm/;/opt/rocm/llvm`.
For detail instructions, please refer to [how to build HIP](https://rocm.docs.amd.com/projects/HIP/en/latest/install/build.html)
## Tests
`hip-tests` is a separate repository hosted at [hip-tests](https://github.com/ROCm/hip-tests).
To run `hip-tests` please go to the repository and follow the steps.
## Release notes
HIP provides release notes in [CLR change log](./CHANGELOG.md), which has the records of changes in each release.
