Hi,

[mahmood@rocks7 mpiBench]$ ls
crunch_mpiBench  makefile  mpiBench.c  README.md
[mahmood@rocks7 mpiBench]$ make
rm -f mpiBench *.o
mpicc  -o mpiBench mpiBench.c

@mahmoodn srun is a command used to submit a job to SLURM, which is a resource manager.

Here is a link to SLURM: https://slurm.schedmd.com/quickstart.html

If you don't have SLURM, or don't want to use it, you can simply run the executables with mpirun or mpiexec.
