oneAPI Deep Neural Network Library (oneDNN)
===========================================
oneAPI Deep Neural Network Library (oneDNN) is an
open-source performance library for deep learning applications. The library
includes basic building blocks for neural networks optimized
for Intel Architecture Processors, Intel Processor Graphics and
Xe architecture-based Graphics.
This package contains oneDNN v@PROJECT_VERSION@ (@DNNL_VERSION_HASH@).
You can find information about the latest version and release notes
at the oneDNN Github (https://github.com/oneapi-src/oneDNN/releases).
Documentation
-------------
* Developer guide (https://oneapi-src.github.io/oneDNN/v@DNNL_VERSION_MAJOR@.@DNNL_VERSION_MINOR@)
explains the programming model, supported functionality, and implementation
details, and includes annotated examples.
* API reference (https://oneapi-src.github.io/oneDNN/v@DNNL_VERSION_MAJOR@.@DNNL_VERSION_MINOR@/modules.html)
provides a comprehensive reference of the library API.
System Requirements
-------------------
oneDNN supports systems based on Intel 64 or AMD64 architectures.
The library is optimized for the following CPUs:
* Intel Atom processor with Intel SSE4.1 support
* 4th, 5th, 6th, 7th, and 8th generation Intel(R) Core(TM) processor
* Intel(R) Xeon(R) processor E3, E5, and E7 family (formerly Sandy Bridge,
Ivy Bridge, Haswell, and Broadwell)
* Intel(R) Xeon Phi(TM) processor (formerly Knights Landing and Knights Mill)
* Intel Xeon Scalable processor (formerly Skylake, Cascade Lake, and Cooper
Lake)
* future Intel Xeon Scalable processor (code name Sapphire Rapids)
oneDNN detects the instruction set architecture (ISA) at runtime and uses
just-in-time (JIT) code generation to deploy the code optimized
for the latest supported ISA. Future ISAs may have initial support in the
library disabled by default and require the use of run-time controls to enable
them. See CPU dispatcher control (https://oneapi-src.github.io/oneDNN/dev_guide_cpu_dispatcher_control.html)
for more details.
The library is optimized for the following GPUs:
* Intel HD Graphics
* Intel UHD Graphics
* Intel Iris Plus Graphics
* Xe architecture-based Graphics (code named DG1 and Tiger Lake)
