If vectorization is really causing these failures, even when simdlen
is eliminated, I worry about the other simd
calls in the relativistic Riemann solvers:
grep '\<simd\>' src/hydro/rsolvers/**/*_rel*
They are all doing pretty much the same thing. The workhorse in most production code is hlle_mhd_rel_no_transform.cpp
. At least I guess that hasn't broken, yet.
yeah, I don't really understand what is wrong. Need to review what (if anything) we learned from #349 and #138
Following #518 and specifically d59c678b796fb25f6da0ef769328ad384068f163, OpenMP-based explicit SIMD was disabled for frame transformation-based HLLE (Hydro and MHD) and HLLC (Hydro) relativistic Riemann solvers. This likely degrades performance; need to diagnose the root cause of the regression test failures:
And need to double check any gaps in GR/SR Riemann solver test coverage for any further correctness issues that may be lurking in the code.
