I have built MPICH on my cygwin installation. The building process was
straight forward. One thing to lookout for is that in MPICH, there are
many files that case sensitive (e.g. mpicc and mpiCC). Make sure you build
MPICH in a directory that is mounted with the "managed" option. You'll
also need rsh or sshd running to use it.

It works just fine on one machine, but I haven't tested it on multiple
machines. I only use it for code development on my laptop when I'm away
from the office.
