AKG简述

AKG(Auto Kernel Generator)对深度神经网络中的算子进行优化,并提供特定模式下的算子自动融合功能。AKG与MindSpore的图算融合功能协同工作,可提升在不同硬件后端上运行网络的性能。

AKG由三个基本的优化模块组成:规范化、自动调度和后端优化。

  • 规范化: 为了解决polyhedral表达能力的局限性(只能处理静态的线性程序),需要首先对计算公式IR进行规范化。规范化模块中的优化主要包括自动运算符inline、自动循环融合和公共子表达式优化等。

  • 自动调度: 自动调度模块基于polyhedral技术,主要包括自动向量化、自动切分、thread/block映射、依赖分析和数据搬移等。

  • 后端优化: 后端优化模块的优化主要包括TensorCore使能、双缓冲区、内存展开和同步指令插入等。

硬件后端支持

当前支持Ascend910NVIDIA V100/A100CPU等,更多硬件后端支持待开发。

构建

从MindSpore侧构建

详细细节请参考MindSpore README.md

独立构建

我们建议您从MindSpore侧构建运行AKG代码,但同时为了方便开发,我们提供了独立编译运行AKG的方式。 详细的编译依赖请参考MindSpore安装指南

  • 构建Ascend910版本

    在下载代码前需安装git-lfs软件

    git clone https://gitee.com/mindspore/akg.git
    cd akg
    bash build.sh -e ascend -j8
  • 构建GPU版本

    git clone https://gitee.com/mindspore/akg.git
    cd akg
    bash build.sh -e gpu -j8
  • 构建CPU版本

    git clone https://gitee.com/mindspore/akg.git
    cd akg
    bash build.sh -e cpu -j8

运行

  1. 设置环境变量
  • Ascend910

    cd tests
    source ./test_env.sh
  • NVIDIA V100/A100

    cd tests
    source ./test_env.sh gpu
  • CPU

    cd tests
    source ./test_env.sh cpu
  1. 运行测试用例
  • 使用测试脚本:
cd tests/st
python run.py -e gpu -o add -l level0  # 执行GPU Add算子的level0用例

使用说明可以python run.py -h查看.

  • 使用测试文件:

    • Ascend910
    cd tests/st/ops/
    pytest -s test_abs.py -m "level0 and platform_x86_ascend_training" # 运行Ascend level0测试用例
    • NVIDIA V100/A100
    cd tests/st/ops/
    pytest -s test_abs.py -m "level0 and platform_x86_gpu_training" # 运行GPU level0测试用例
    • CPU
    cd tests/st/ops/
    pytest -s test_abs.py -m "level0 and platform_x86_cpu" # 运行CPU level0测试用例
