OpenBLAS test suite failures on ARM neoverse_v1 #314
Comments
@casparvl Can you include the high-level summary that shows how many tests fail, and maybe also dig up more details on the failing tests (should probably go in a gist), which we can use when reporting this upstream (or getting some input on this from @bartoldeman)? |

@casparvl , I have created a PR (easybuilders/easybuild-easyconfigs#19280) to address most of the numerical errors by disabling tree-vectorize. This is also disabled in OpenBLAS main branch and OpenBLAS release 0.3.23. See For users who have a concern of potential performance degradation, I have validated that all these are small numerical differences. Details can be found at OpenMathLib/OpenBLAS#4335. |
Indeed, for OpenBLAS 0.3.23 and newer we don't see an increased number of numerical test failures anymore on from

We're seeing somewhat higher number of OpenBLAS test suite failures on ARM neoverse_v1 in:
For now, we've increased the number of accepted failures, but we'll need to investigate this issue in more detail. Are these test just out of numerical bounds? Or way off?
