[mvapich-discuss] Readme mpiexec example is not working

[Jonathan Perkins]

Bright:
I'm not sure why you're experiencing a problem using this syntax.  Are
you sure that the mpiexec that is in your path corresponds to
mvapich2-1.7a2?

You can use `which mpiexec' to verify the path.  Here is an example of
mpiexec usage from one of my installations.

[perkinjo at head examples]$ ../install/bin/mpiexec -f 2_8hosts -n 16 ./cpi
