HIP 是 开源的 AMD 上的异构并行计算框架, 其类似于 Nvidia 的 CUDA. QUDA 则是 Lattice QCD 中广泛使用的 cuda 库. 我们需要将 quda 从 CUDA 平台移植到 AMD 的 HIP 平台. 方便的是, HIP 提供了几个脚本来帮助我们实现这一过程.

QUDA from cuda to hip

There are tools for transcode quda from cuda to hip - hipify-perl and hipify-cmakefile for source codes and cmake files respectively.

rocRAND

  1. download googletest
$ git clone https://github.com/google/googletest.git
$ mv googletest googletest-src && tar cvjf googletest-src.tar.bz2 googletest-src
$ tar xf rocRAND-1.8.0.tar.gz && cd rocRAND-1.8.0
$ mkdir build && cd build
$ CC=gcc CXX=g++ cmake3 .. -DCMAKE_HIP_COMPILER_ENV_VAR=hipcc  -DHIP_TOOLKIT_INCLUDE=/opt/rocm/hip/include/hip -D__HIP_PLATFORM_HCC__=hcc -DCUDA_cuda_LIBRARY=/opt/rocm/hip/lib/
### error may occur when download googletest
sed -i "6,9d " googletest-download/googletest-download-prefix/tmp/googletest-download-gitclone.cmake
touch  googletest-download/googletest-download-prefix/src/googletest-download-stamp/googletest-download-gitclone-lastrun.txt
### then re-run cmake
$ CC=gcc CXX=hcc cmake3 .. -DCMAKE_HIP_COMPILER_ENV_VAR=hipcc -DHIP_TOOLKIT_INCLUDE=/opt/rocm/hip/include/hip -D__HIP_PLATFORM_HCC__=hcc -DCUDA_cuda_LIBRARY=/opt/rocm/hip/lib/
$ make -j4 && make DESTDIR=$HOME/ install

cublas

  1. include/blas_cublas.h : <cublas_v2.h> -> <rocblas.h>

  2. include/cub_helper.cuh: adding #include<rocblas.h>

  3. include/cub_helper.cuh: adding #include<thrust/system/cuda/detail/cub/cub.cuh>

  4. hip_helpers/forwarder.hpp
    - device/dispatch/dispatch_histogram.cuh
    - device/dispatch/dispatch_reduce_by_key.cuh

  5. adding hip_helpers/forwarder.hpp from here

  6. uncomment line 125 of cub_helper.cuh:// shared bool isLastBlockDone;

  7. shared bool -> bool
