Testing of support for VSX instruction set?

Open alanw0 opened this issue 5 years ago • 1 comments

This is maybe more of a question than an issue... Is there a dashboard or any testing code for the support of the various instruction sets?

We (STK) have a user (nalu-wind) that decided to do a host-only (no cuda) build/run on summit (IBM/POWER9, which has VSX/altivec instruction set) and found that they are getting nans in the solver, and traced it back to the commit where we activated kokkos-simd. We currently don't have any testing for VSX in Sierra, since our ATS-2 builds have cuda activated, meaning we only get scalar-simd. FYI @tasmith4 @sayerhs

@alanw0 I think the short answer is we don't have a dashboard right now for testing across instruction sets. Personally I think this won't really happen until its merged into Kokkos and leverages the Kokkos testing infrastructure.
