I can confirm that with NOLOCAL, some processes are stuck in BARRIER while one process is stuck in MPI_Waitsome
Dear Robert, That barrier is likely a subordinate call inside the top-level Bcast, no? I don't have any Barriers in the code, as I recall. The Waitsome issue is indeed what I saw with my printf debugging, although it really only clarified the symptom.
I hope someone more familiar with the collectives can suggest a fix. For now, I've triaged this in issue #2609
Let me know if there is something else I can do to help here. Cheers, Jason _______________________________________________ discuss mailing list [email protected] To manage subscription options or unsubscribe: https://lists.mpich.org/mailman/listinfo/discuss
