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 :(
