**user1@user1-ThinkPad-E520:$ cd /home/user1/Desktop/qe/SCF
user1@user1-ThinkPad-E520:/Desktop/qe/SCF$ mpirun -np 2 pw.x < Sample-1.pw.in > Sample-1.pw.out

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.
