UCX error in OpenMPI-4.1.1 foss-2021a build #756
Comments
@connorourke This looks a lot like the problem reported upstream at openucx/ucx#4224 . Are you running in a user namespace? |

@boegel I just hit the exact same issue with the foss-2021b toolchain. The strange thing is that it happens on certain machines while on others it builds smoothly. @connorourke On which hardware were you trying to build it? |
It was on an AMD Milan EPYC 7V13. |

Has anyone seen this error and knows a fix?
