Mike (or indeed anybody else who might know)

Can you post a reference to the list for Jim Pepin's ppt ?
Google didn't come up with anything useful

Closest might be "Building and Benchmarking a 10 TF Linux Cluster" Jim Pepin,
USC at Sun HPC consortium 2005 but can't find any online resources for this ?

Also, check out the changes that Jim Pepin at USC made to his cluster to 
produce more teraflops. There is a Powerpoint on the web that gives some 
of the details. If I remember correctly he actually removed RAM from the 
nodes and made a few other changes.
