About

Important component of HPC stack. Implementations relevant to RISE are (obviously) LLVM and GCC. gomp (GCC) has been operational for some time and we've been tracking the progress of LLVM OpenMP on RISC-V.

OpenMP implements fork-join multithreading model and starting with version 5 it supports device offload.

Dependencies

Full testing of offload support requires device drivers.
