Where is srun?

Nobody has claimed this yet.

Hi,
What is that `srun`? I don't see that file after make

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

```

Start by reading README.md and makefile, then search them for references to `srun` and compare those instructions with the files produced by `make`. Clarify whether `srun` is expected to be built or is an external launcher, and ensure the documented build and run steps match the repository; the issue is done when a user can determine how to run the benchmark.
