HIP

HIP API, as described in https://github.com/ROCm-Developer-Tools/HIP

Test case for development

src/gpu_runtime/build-cmake.sh &&  python examples/pytorch/test_create_tensor.py

Pre-requisites

  • pytorch HIP only supported on linux
  • must have installed pytorch HIP version
  • must have gone into lib/python*/site-packages/torch/lib, and
    • removed/moved the following files:
      • libamdhip64.so
      • libhsa-runtime64.so
      • libroctx64.so
    • must have created symlinks from ${VERIGPU}/build-runtime/libverigpu_runtime.so, where ${VERIGPU} is the absolute path to the VeriGPU repository, to files in the above lib directory, with the exact same names as those moved
  • must have all pre-requisites for running VeriGPU single-source, examples/cpp_single_source/README.md

(Note that in the future, we will need to compile pytorch from scratch, since we need to compile the kernels ourselves, into RISC-V).
