Hi All, This program runs fine on 2 cluster nodes but crashes with "MPI_BARRIER(mpi_comm_world_failed)" message when I try to run it on more nodes.  I'm using mpif90 gfortran.  Any ideas anyone? Thanks, Bill _______________________________________________ discuss mailing list [email protected] To manage subscription options or unsubscribe: https://lists.mpich.org/mailman/listinfo/discuss
