"This is another significant step in the evolution of this important system," said Peter Ungaro, president and CEO of Cray. "Initially a 40 teraflops machine, this is its second major upgrade, adding in Cray XT4(TM) technology to take Red Storm to seven times its original performance level. Cray's entire line of MPP systems is built to be uniquely expandable and upgradeable, and Sandia has substantially leveraged their original investment while achieving the Department of Energy's NNSA program's ambitious computational goals. This new performance level will allow researchers to tackle even larger computational problems including calculations that have never been successfully completed before."
