Dear Researcher, On behalf of the Center for Computational Science and the Scientific Computing and Visualization group in the Office of Information Technology, we are very pleased to announce the recent addition of an IBM Blue Gene/L supercomputer to the University's Scientific Computing Facility. This system represents a substantial enhancement to our facilities and provides us with one of the most powerful computing platforms in the world. Our system is a single rack comprising 1024 dual-processor compute nodes with an aggregate peak performance of 5.7 TFLOPS. Our machine ranked 59th on the most recent TOP500 list of the fastest computers in the world. Boston University was the fith site in the US and eighth site in the world to install a Blue Gene system. We have given a small number of "friendly users" accounts on the machine in order to help us get it ready for the general user community. Although we are not yet ready to open it to all users, we would like to allow additional "friendly users" to have access as part of our testing phase. Our friendly-user guidelines can be viewed at http://scv.bu.edu/scv/fug.html. During the testing phase there is no charge for CPU time. Candidate users should have codes that have been parallelized using MPI, and we can help with the porting process if need be. Ideally, the codes should scale well on large numbers of processors. Codes that currently run in the p4-mp32 queue would be good candidates. If you are interested in participating in this testing phase, please reply to this e-mail, and we will give you further details. --SCV
