Can someone who knows/cares about ARM perhaps take a look at PR https://github.com/open-mpi/ompi/pull/5247 <https://github.com/open-mpi/ompi/pull/5247>? I’m hitting an error in the ARM CI tests that I can’t understand:
--> Running example: hello_c -------------------------------------------------------------------------- Failed to create a completion queue (CQ): Hostname: juno001 Requested CQE: 16384 Error: Cannot allocate memory Check the CQE attribute. -------------------------------------------------------------------------- -------------------------------------------------------------------------- Open MPI has detected that there are UD-capable Verbs devices on your system, but none of them were able to be setup properly. This may indicate a problem on this system. You job will continue, but Open MPI will ignore the "ud" oob component in this run. Hostname: juno001 -------------------------------------------------------------------------- vsetenv PMIX_SERVER_TMPDIR failed vsetenv PMIX_SERVER_TMPDIR failed vsetenv PMIX_SERVER_TMPDIR failed vsetenv PMIX_SERVER_TMPDIR failed I get the UD error - that has been around for years since nobody seems to care about or maintain the ud/oob component. What I don’t understand is why setting an envar would fail solely in the ARM environment. Could someone maybe at least provide a hint as to what is going on? Thanks Ralph
