it's process 0 which is aborted but I have seen other processes as well reporting the crash. We are using mpich-3.2.1. I'm trying to understand possible causes for this error? I have explored the forum and no possible causes, like machine going out of memory
etc are applicable here. Please suggest. Are there any debug/log/trace options I can use with mpiexec to further root cause?</span><o:p></o:p></p>
