You are using MPICH. You should ask submit your question to their
mailing list to get the most accurate answers. From the log you
provide, I can still guess that you need to define a machinefile
containing at least 4 computing ressources. If you need more details
concerning machinefiles in MPICH, you should definitely consult the
MPICH faq/users manual.
