[mpich-discuss] Cluster problem running MPI programs

[Brice Chaffin]

Thank you.

I'll look at building mpich2 in a better way now that I at least got a
trial version running. The tutorials were Ubuntu specific and older, so
mpd probably wasn't deprecated when they were written. 

I'll check the README file and rebuild mpich2.

If the problem persists with Hydra, I'll let you know.

Thanks again.:)
