Eric, can you make your test case (source + input file + howto) available so i can try to reproduce and fix this ?
Based on the stack trace, i assume this is a complete end user application. have you tried/been able to reproduce the same kind of crash with a trimmed test program ? BTW, what kind of filesystem is hosting Resultats.Eta1 ? (e.g. ext4 / nfs / lustre / other) Cheers, Gilles On 2014/12/15 4:06, Eric Chamberland wrote: > Hi, > > I finally (thanks for fixing oversubscribing) tested with 1.8.4rc3 for > my problem with collective MPI I/O. > > A problem still there.
