Hi all, Please, some clarification. I have built Open MPI 1.4.1 against our IB verbs layer, and all seems well. But a question has come up about IPoIB. While all communications are using the "native" IB interface (verbs), will mpirun use IPoIB during job launch and teardown? If it matters, re

I sent that last message to quick. I was ignoring that MPI_Abort already takes two args. I've been doing a lot of Perl the past few weeks, so I'm in a perl state of mind. I would say add a third arg to MPI_Abort for a programmer-defined error string, but that would violate the standard, wouldn't

I would suggest that MPI_Abort take a string as an argument, and print out the that string when MPI_Abort is called. If a programmer wanted to NOT have an abort message, they could just omit the argument: MPI_Abort("Could not open file foo"); or MPI_Abort(); This would be similar to Perl's die

2010-04-05 Thread Richard Treumann
Thanks Ralph Should have considered that. The assumption would be that anyone who is using the message suppression option is (or at least should be) wrapping the job launch in some script or other tool that records a non-0 RC as a job failure or raises a flag for them to say the job failed. A

Not all distinctions - the exit status is non-zero. All that is suppressed are the messages telling you what the error -might- have been. On Apr 5, 2010, at 7:01 AM, Richard Treumann wrote: > Why should any software system offer an option which lets the user hide all > distinction between a run
