This looks like an old e-mail.  I keep getting it again.

	Subject: [GE users] mpich machinefile hostlist
	
	
	Hello,
	I have a question about using MPICH with SGE.   Is it possible
to =
	specify in a parallel
	environment on SGE (e.g. mpich) which nodes in the grid work on
which
	modules?  For instance in a parallel environment which has 3
modules, =
	we'd
	like to have 2 nodes be allocated for module 1, 6 nodes for
module 2 and =
	1
	node for module 3.  How do we do this?  Is it by using the
"-machinefile =
	<hostlist_file>" command ? If so, can you give me an example.
If not, =
	then how is it done?  Thanks so much.
	
	Jon
