[mpich-discuss] mpich hangs

[Syed. Jahanzeb Maqbool Hashmi]

As I already read some discussion on the mpich thread and I came to know
these questions before:

   - *Can you ssh from "node01" to "node02"?*
   Yes I have passwordless ssh from each node to other (and vice versa)
   - *Make sure the firewalls are turned off on all machines.*
   I am using Ubuntu Linaro, 12.04, and I have no firewall installed on all
   the nodes.


Any other workaround :(
