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?
