<p class="MsoNormal">I have a couple of questions about abnormal termination. The EXIT CODE below is 11, which could be signal SIGSEGV, or is it something defined by MPICH? If it is SIGSEGV, it is strange because my signal handler isn’t catching it and cleaning
up properly (the signal handler calls MPI_Finalize()). Is there any way to get more information about the location of the error?<o:p></o:p></p>
