[mpich-discuss] mpich2 MPI_TEST errors

[Pavan Balaji]

Samir,

Can you send the test program? If all channels are failing, it is very 
likely either a problem with the test program or your configuration. 
Btw, which version of MPICH2 are you using?

Regarding the new cluster, all you need to use it ch3:nemesis. In a lot 
of ways, nemesis is a superset of sock, ssm and shm. The few features 
that it is missing (which you'll only notice in special circumstances) 
are being added in the 1.1 release of MPICH2.
