* Restructure ROCM Library Search Currently there are a handful of ROCM dependant files which are required for triton to run. The linker(ld.lld), the include files, and multiple hip/hsa shared objects. This change will provide three search areas to find these files. All in the same order. 1. third_party/rocm. This location is within the python/triton directory and is carried over when triton is built. IF all necessary files are in this location there will be no need to have ROCM installed at all on the system. 2. $ROCM_PATH environmental variable. If this exists it will override all other locations to find ROCM necessary files 3. /opt/rocm. The default location for ROCm installations. Finding one here will notify triton that ROCM is installed in this environment To ease with step 3. A new script scripts/amd/setup_rocm_libs.sh has been added to the repo. Executing this script will cause all necessary ROCM files to be downloaded from their respective packages on repo.radeon.com and installed in third_party/rocm. Allowing for triton to run without installing the full ROCM stack. setup_rocm_libs.sh takes a env_var ROCM_VERSION if a user wishes to install a ROCM version other than the default (currently 5.4.2) When triton whls are built to support Pytorch, method 3 will be used to stay in sync with PyTorch's approach of bringing along any libraries needed and not requiring ROCM to be installed.
