OK, Thank you for your help. I'll will do it.
But, is it still possible to restart a mpi program previously checkpoint, on another different nodes ? And also, i don't know how to look at the core file from segfault to send you the backtrace. If you can guide me. Thank you. Hope to read you. Best regards. 2015-04-15 4:19 GMT+01:00 Ralph Castain <r...@open-mpi.org>: > I’m afraid I don’t know much about that code, but I can try to help.
