HIP on Aurora: Bringing HIP to oneAPI

Future DOE exascale system will be based on AMD (Frontier, El Capitan) or Intel (Aurora) hardware. HIP is thus a likely target for many Exascale applications, and HIP on Aurora ECP project’s objective is to bring portability to those application by offering HIP support on top of oneAPI. Derived from University of Finland’s HIPCL, our new HIP backend CHIP-SPV can target Intel GPUs through either Level Zero or OpenCL runtimes. To achieve this goal the HIPLZ project contributed the required changes to enable SPIR-V generation from HIP in LLVM/Clang14.
