It turns out that this problem, specifically the segfault, wasn't related to two ipath cards as it was that one of the ipath cards was running at a scant 2% of the overall speed of the IB fabric and as such was causing excessive retries that closed the connection and the mpitest program wasn't built to deal with connections going away unexpectedly and as a result segfaulted. As such, I'm closing this as NOTABUG. The problem went away when the test network was updated to get rid of the slow connection that was disrupting the IB fabric. |
