Re: [OMPI users] MPIRUN SEGMENTATION FAULT

[Andy Riebs]

The challenge for the MPI experts here (of which I am NOT one!) is that the problem appears to be in your program; MPI is simply reporting that your program failed. If you got the program from someone else, you will need to solicit their help. If you wrote it, well, it is never a bad time to learn to use gdb!

I have got three files as an output when the executable is used. One is the actual output which stops and the other two are error files (from which I knew about the segmentation fault). thanks From: users <users-boun...@open-mpi.org> on behalf of Ralph Castain <r...@open-mpi.org> Sent: Saturday, April 23, 2016 11:39 AM To: Open MPI Users Subject: Re: [OMPI users] MPIRUN SEGMENTATION FAULT   valgrind isn’t going to help here - there are multiple reasons why your application could be segfaulting. Take a look at the core file with gdb and find out where it is failing.

However when I started using the executable with mpirun, the code stopped with the following error: "mpirun noticed that process rank 0 with PID 570 on node compute-1-9.local exited on signal 11 (Segmentation fault)."
