    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 four basic optimization module, normalization, auto schedule, instruction emit 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 partition, common subexpression elimination and so on.

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

    • instruction emit. The instruction emitting module has the optimization about loop normalization, auto pragma and emit instruction.

    • backend optimization. The backend optimization module consists of double buffer optimization, storage rewrite optimization and inject sync optimization.

    Hardware Backends Support

    At present, Ascend910 is supported only. 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. Ascend platform is needed to build this mode. Refer to MindSpore Installation for more information about compilation dependencies.

    bash build.sh

    Run Standalone

    1. Set Environment
    cd tests
    source ./test_env.sh amd64
    export RUNTIME_MODE='air_cloud'
    export PATH=${PATH}:${YOUR_CCEC_COMPILER_PATH}
    1. Run test
    cd tests/operators/vector
    pytest -s test_abs_001.py -m "level0" # run level0 testcases
