title: error in mpirun command
body: <pre><code>       --------------------------------------------------------------------------
          MPI_ABORT was invoked on rank 2 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.
             --------------------------------------------------------------------------
            --------------------------------------------------------------------------
          mpirun has exited due to process rank 2 with PID 19175 on
           node mosura15 exiting without calling "finalize". This may
              have caused other processes in the application to be
              terminated by signals sent by mpirun (as reported here).
