Yes, actually the requirement to run parallel mode of RegCM is very less,
just MPICH (or openmpi) installation.

If you have several computer or several multiple servers which connected
by fast network, and each of them has MPICH installed, then it's also 
fine. In the previous RegCM workshop, I have seen one student run RegCM
in parallel as this way, he prepare one file which contains the computer
names he plan to use.

Honestly, the clusters and supercompters I used are not that complicated.
I just simply use mpirun or mpiexec (on Linux cluter by using qsub) and 
poe (on IBM SP server by using poe, or mpirun, or llsubmit).
