Bruce- 

Thanks for the response.  I really didn't want to run TCP over
Myrinet as it really takes away part of the advantage of running myrinet.
The Myrinet performance over TCP looks pretty poor.  I am far from
qualified to make ICS run natively, so I guess it is OpenMosix on my
home cluster for now.
