[mvapich-discuss] Fatal Error in MPI_Init

[Gus Correa]

Hi Sunny
Glen is right.
Check if you can ssh without password from node1 to node2 and vice-versa.
If not, set this up with ssh keys or host based authorization.
Check if the nodes' names are resolved to the right IP
addresses (ping node2 from node1 and vice-versa).
Turn off firewalls, if they are on.
