Computational Resources

 

Most of our serious computational work is done off-site at one of several national supercomputing centers.  However, we do maintain a large number of local machines which are used for smaller calculations and for graphical data analysis.  In the next few months we will be drastically increasing our local computational capabilities as we construct a Beowulf cluster using Myrinet interconnects.
