论文摘要
随着AMD在科学高性能计算生态系统中加强了他们的野心，我们将银杏线性代数软件包的硬件范围扩展到了AMD GPU的髋关节后端。在本文中，我们报告并讨论了CUDA的移植工作，髋关节框架的扩展是添加缺失的功能，例如合作组，为AMD架构编译髋关节代码的性能价格以及为NVIDIA和AMD GPU提供本机后端的图书馆设计，同时通过使用共享代码基础来最大程度地减少代码基础。
With AMD reinforcing their ambition in the scientific high performance computing ecosystem, we extend the hardware scope of the Ginkgo linear algebra package to feature a HIP backend for AMD GPUs. In this paper, we report and discuss the porting effort from CUDA, the extension of the HIP framework to add missing features such as cooperative groups, the performance price of compiling HIP code for AMD architectures, and the design of a library providing native backends for NVIDIA and AMD GPUs while minimizing code duplication by using a shared code base.
