Public bug reported: Running MPI jobs or some ucx_perftest tests with Genoa CPUs and Infiniband fails when ucx is built with a gcc version newer than 10.3 due to optimizations that convert code into "memmove" calls. I worked with Nvidia to identify and resolve the issues. Here's the links to the 2 patches that resolve the issue:
https://github.com/openucx/ucx/pull/9692 https://github.com/openucx/ucx/pull/9714 Please include these patches into the ucx package to resolve the issues. ** Affects: ucx (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2055222 Title: ucx library fails with Genoa CPUs and InfiniBand To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ucx/+bug/2055222/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
