problem

Hi
H worte a an example but when I run it this error has apeared

ERROR on proc 0: Cannot open dump file (dump.cpp:392)
--------------------------------------------------------------------------
MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_WORLD
with errorcode 1.

NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.
You may or may not see output from other processes, depending on
exactly when Open MPI kills them.
I don't know how to fix it.
thanks so much for your usefull command.
Best Regards Mozhgan
