[MPICH] MPICH2 hangs on diskless SuSE 10.2 based cluster

[Rusty Lusk]

I recommend that you follow the steps in the User's Guide starting  
with the use of mpdcheck to make sure both machines are properly  
configured and can communicate with one another, and start the mpd's  
on these two machines "by hand" instead of going immediately to the  
more scalable but less informative mpdboot.

Rusty
