The Department of Energy’s National Energy Research Scientific Computing Center [NERSC] has officially accepted a series of upgrades to its Cray XT4 supercomputing system.  The upgrade to Franklin included a phased series of quad-core processor upgrades and memory upgrades.
Franklin‚Äôs upgrade has already provided a tremendous benefit to the DOE computational science community, which now has a system in which the aggregate system performance is double that of the original Franklin system,‚Äù says Kathy Yelick, NERSC Division Director. ‚ÄúThe key to improving application throughput is to maintain balance for that workload, so when we doubled the number of cores, we also doubled the memory capacity and bandwidth, and tripled the I/O bandwidth…‚Äù
