What Is AKG

AKG(Auto Kernel Generator) is an optimizer for operators in Deep Learning Networks. It provides the ability to automatically fuse ops with specific patterns. AKG works with MindSpore-GraphKernel to improve the performance of networks running on different hardware backends.

AKG composes with three basic optimization module, normalization, auto schedule and backend optimization.

• normalization. In order to solve the limitation in expression ability of polyhedral(which can only process static linear programs), the computation IR needs to be normalized first. The mainly optimization of normalization module includes auto-inline, loop fusing, common subexpression elimination and so on.

• auto schedule. Base on polyhedral technology, the auto schedule module mainly have auto-vectorization, auto-tiling, thread/block mapping, dependency analysis and memory promotion.

• backend optimization. The backend optimization module mainly consists of TensorCore acceleration, double buffer optimization, storage flatten optimization and inject sync optimization.

  

Hardware Backends Support

At present, Ascend910 and GPU V100/A100 are supported. More Backends are on the list.

Build

Build With MindSpore

See MindSpore README.md for details.

Build Standalone

We suggest you build and run akg together with MindSpore. And we also provide a way to run case in standalone mode for convenience sake.
Refer to MindSpore Installation for more information about compilation dependencies.

• Build on Ascend910

  git-lfs needs to be installed before cloning the source codes.

  git clone https://gitee.com/mindspore/akg.git
  cd akg
  bash build.sh -e ascend
  

• Build on GPU

  git clone https://gitee.com/mindspore/akg.git
  cd akg
  bash build.sh -e gpu
  

Run Standalone

1. Set Environment

• Ascend910

  cd tests
  source ./test_env.sh
  

• GPU V100/A100

  cd tests
  source ./test_env.sh gpu
  

2. Run test

• Ascend910

  cd tests/st/ops/ascend/vector
  pytest -s test_abs_001.py -m "level0" # run level0 testcases
  

• GPU V100/A100

  cd tests/operators/gpu
  python3 test_all.py "op_name" # replace op_name with the operator name which you want to test
