Mohamad,

How would I find the MPICH version for myricom?  If there is a way to query
the system, I'll do that tomorrow when I re-run the mpio test (I've run it
before, but I don't know that I tried different ppn vs. node distributions).

Also for the configure and make output, can I simply send those as an
attachment with a reply email?
