I know that it is usually frowned upon to respond to your own
posting, but since I haven't gotten much of a response I thought I should
give some additional info to see if that might help.

	I have been using PVM on our SUN network here at UNC-Charlotte
since earlier this spring. It is a pain to do because I don't have rsh
or rexec access to machines, only rlogin. PVM does provide a work around
for this by allowing you to specify a manual start of pvmd on your remote
machines.
	The professor that I am working with on this, has attended workshops
where MPI was discussed, and was interested to see if we could try to use
it here in addition to or instead of PVM for the Parallel Programming class
that he teaches. I was able to get the mpich implementation of MPI installed,
and it seems to work fine using the ch_p4 device on a single machine. This
of course isn't very interesting though, and I can't seem to find any info
on starting the "secure server" for MPI without rsh capabilities.
	I have beginning to believe that the this is not possible given the
lack of documentation on the subject. If anyone has any experience with this
using any freely distributed implementation of MPI I would be VERY grateful
to hear of it.
	Thanks in advance for your time and assistance.
