For running the program in parallel, I write: mpirun -np 4 ~/program <input> output
It takes a second that I receive the message: mpirun noticed that job rank 0 with PID 9477 on node linux-4pel exited on signal 15 (Terminated).
and at the end of the output file, I receive: "3 additional processes aborted (not shown)"
Please help me I am really in short of time to run this program. If there are other things needed, please let me know to provide.
