But it seems the CPU does not support AVX/AVX2 instructions. It is likely a duplicated issue of https://bugzilla.redhat.com/show_bug.cgi?id=1659852 . Anton, could you please have a look? At first pass, I would agree with Hongang. I've added Adam G. to take a closer look. Keeping NEED INFO flag. Agreed, with Anton and Hongang, PSM3 is only meant to be run on AVX or higher CPUs. Clearing need info flag for anton.bodner Sorry, 2nd attempt So is this a bug in openmpi, as it shouldn't call `fi_getinfo` on non-AVX CPUs, or is this a bug in libfabric? I assume the fix for https://bugzilla.redhat.com/show_bug.cgi?id=1659852 for the PSM2 could also be applied for PSM3?

But it is unlikely will be fixed for old CPUs. As you see, bz1659852 hang on for 2.5+ years without fix. This message is a reminder that Fedora 33 is nearing its end of life. Fedora will stop maintaining and issuing updates for Fedora 33 on 2021-11-30. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '33'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 33 is end of life.

Fedora Linux 34 entered end-of-life (EOL) status on 2022-06-07. Fedora Linux 34 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. Thank you for reporting this bug and we are sorry it could not be fixed. |
