I've got a mpi program that is supposed to to generate a core file if problems arise on any of the nodes. I tried to do this by adding a call to abort() to my exit routines but this doesn't work; I get no core file, and worse, mpirun doesn't detect that one of my nodes has aborted(?) and doesn't kill off the entire job, except in the trivial case where the number of processors I'm running on is 1. I've replaced abort with MPI_Abort, which kills everything off, but leaves no core file. Any suggestions how I can get one and still have mpi exit?
Thanks in advance. David
