This system has a peak capability of 5.7 TFLOPS and represents a vast increase in our production capabilities. Our machine is ranked among the top 100 fastest computers in the world. Our Blue Gene is being used very successfully by a number of researchers from our community during our extended Friendly User period. At this time we would like to make this important resource available to all of our researchers. At the same time we will be making some small changes to our procedures for issuing computer accounts and will initiate this procedure for new users of the Blue Gene system. Over the next few weeks we will send out more details on this process. Once the Blue Gene goes into production, we will be charging for its use against your research project's computer time allocation. Our machine comprises 1024 compute nodes. Each compute node contains two PowerPC processors running at 700MHz and 512 MB of memory. The charge rate will be 0.25 SUs per node-hour . (One SU equals one processor hour on the p690). Unlike the p690 and Linux clusters, the charge is based on the job's actual running time (i.e. wall-clock hours), not processor (CPU) hours. This offers a quite favorable rate for those jobs that can take advantage of the Blue Gene architecture, particularly those that can utilize both processors on a node. For more information on the BG/L, please visit the SCV Web site at http://scv.bu.edu/SCV/bluegene.html. If you would like to start using the Blue Gene immediately, you may still apply for a Friendly User account following the instructions on the Web page. We will be sending out further information on obtaining access to the Blue Gene over the next few weeks. We are most pleased to be able to bring this resource into production and hope you will be able to make good use of it in furthering your research.
