Beginning Beowulf

I am part of a group of two, basically me and another guy. His name is Derick. Our project is to build a Beowulf Cluster for a Client that wants to make a program run faster than with a single computer. We are using Ubuntu 10.10. We are currently using three dual core machines with an option for more. Before we started this, the client ran a program called CBC on a quad core machine and it took about a day and one half. Our goal is to cut that time by a significant amount. We are currently employing the use of mpich2, nfs, rsh, ssh, cbc, g++, and gcc on the nodes of this Beowulf cluster. I will get the specs for the dual core machines and post them here if I can. Feel free to leave comments and questions.
