[mpich-discuss] can't boot all once

[Pavan Balaji]

Hello,

There might be a network setup issue on your system. You can use the 
mpdcheck utility to debug it.

Alternatively, assuming you are using a new enough version of MPICH2, 
you can use mpiexec.hydra instead. Usage instructions for mpiexec.hydra 
are available here:
