[mpich-discuss] CPI test fails under Fedora 10

[Pavan Balaji]

Does it work on one machine? Note that both machines should be able to 
see the installed copy of MPICH2. So, you can either install it to a 
volume that's shared by both machines, or install it independently on 
each machine in the same location (e.g., /tmp or preferably a persistent 
volume such as /home).

Btw, FC10 should have MPICH2 binaries in their repositories, so "yum 
install" should work fine as well (though installing from source is 
obviously the preferred method).
