Background

Parallel applications are candidates for the Grid, and a number of them uses MPI libraries. MPICH-G2 is MPICH implementation for globus devices. MPICH-G2 provides TCP communication between the nodes where the application processes are scheduled. This assumes that all slave nodes are public IP addresses which is seldom the case. As such, the compute nodes on one cluster are not able to communicate with nodes of the other.

The Solution

Realm Specific Internet Protocol (RSIP) in conjunction with DNS service can overcome this problem. It is an alternative to the Network Address Translation (NAT). It preserves end-to-end packet integrity, a feature not provided by NAT. As such, applications such as MPICH-G2 projects which requires end-to-end packet integrity will work using RSIP.

About the Workshop

This workshop introduces RSIP and explains how to deploy RSIP in a cluster so that the cluster can be enabled to run MPICH-G2 applications without the need for a Public IP address for each node. A demo on an existing RSIP deployment will be shown.
