Hi, I am using mpich-3.1.4 configured —enable-thread-cs=per-object. Every time I execute it I get the following assertion error: "Assertion failed in file src/mpid/ch3/channels/nemesis/src/ch3_progress.c at line 639: pkt->type >= 0 && pkt->type < MPIDI_CH3_PKT_END_ALL" However, if I compile mpich without —enable-thread-cs=per-object everything works correctly. Any help on this? Thanks, Guillem Blanco. _______________________________________________ discuss mailing list [email protected] To manage subscription options or unsubscribe: https://lists.mpich.org/mailman/listinfo/discuss
