Since the Live CDs have become ever popular, playing with an alternative OS has become very much simple yet effective. Even High Performance Computing is not untouched from the Live CD revolution. Initially, a Cluster or a High Performance Computing environment was only a cup of tea for those organizations with six figure annual budgets. But now anyone having LANed computers (Preferably with Gigabit) can easily turn his/her network in to a true High Performing Cluster by using just a Live CD with an OS preconfigured with a parallel computing middleware such as OpenMOSIX, OSCAR etc.
You can download any of the following live CDs for HPC environment:
ClusterKnoppix from : http://clusterknoppix.sw.be
The Bootable Cluster CD from : http://bccd.cs.uni.edu/
ParallelKnoppix from : http://parallelknoppix.cebacad.net/
CHAOS from : http://www.midnightcode.org/projects/chaos/
Boot each node in a network by popping up the live CD and configure the network addresses and eventually convert your office network to a High Performance Cluster ready in no time!
