Ron,

First, sorry for getting so excited... this problem has been bugging me 
all day.  I am having some problems with MM5 with regards to deleting 
the processes since shutting of "control slaves".  Most of my other MPI 
jobs are running much better.  So, shutting off control_slaves disables 
tight integration?

To answer your questions:

1) I have the precompiled binaries.  That is what I have always used on 
all of our other clusters.
2) Here are my settings:

Parallel Environment

slots             44
user_lists        NONE
xuser_lists       NONE

allocation_rule   $round_robin
control_slaves    FALSE
job_is_first_task FALSE
urgency_slots     min

3) As for the processes, on the primary execution node, I see 
sge_shepherd-96 -bg, my job script, the mpirun command and the slew of 
rsh calls that go with it.  On all other slave nodes, I see only in.rshd 
and two copies of the mpi binary that I originally started with mpirun.

Hope this helps.
