【任务说明】

  • 任务标题:在 Paddle 中使用 CUDA Graph 加速训练

  • 技术标签:深度学习框架,CUDA Graph

  • 任务难度:困难

  • 详细描述: CUDA Graph 可以通过预定义静态子图的方式加速 Kernel 调度,进而加速模型训练。独立的性能测试显示其对 Kernel 调度有显著加速。这个任务的目标是把 CUDA Graph 引入 Paddle,加速 Kernel 调度,进而加速模型训练。可以分为两个子目标:

    (1) 定义并实现 CUDA Graph Python 层 api,用户可以使用 api 完成构建子图,执行子图,包含但不限于

    • 子图构建 (capture 方式,或 sub-graph 方式)
    • 子图执行
    • 子图同步

    (2) 将 CUDA Graph 已一定的方式可以在框架中自动的使用,框架自动的完成构建子图,执行子图。

【提交内容】

  • 任务提案

  • 任务 PR 到 Paddle

  • 相关技术文档

  • 任务单测文件

【技术要求】

  • 熟练掌握 C++

  • 了解 CUDA Graph 相关的技术背景
