[mpich-discuss] MPICH-G2 private clusters

[Ravi Thati]

Hello all,

          Actually I have been trying to work with MPICH-G2 with private IP
clusters. I have been tracing through the code in order to identify how the
communication is happening.

 Now I have got some idea that ,MPI initialization is done at the start up
which exchanges host name + port details.

If I have to get the packets to private IP nodes I have to do some NAT in
head nodes to forward the packets.  But how to send packets from the private
IP nodes to other nodes working outsides some other cluster. The destination
node may be there in any cluster which wil be decided dynamically. How is
the packet need to be transferred via the Head node to other clusters head
node??

any ideas would be a great help.
