Jaguar is the scientific research community’s most powerful computational tool for exploring solutions to some of today’s most difficult problems. The upgrade, funded with $19.9 million under the Recovery Act, will enable scientific simulations for exploring solutions to climate change and the development of new energy technologies.
With 2.595 petaflops of raw power , Jaguar is fastest computer on the planet.
Jaguar began service in 2005 with a peak speed of 26-teraflop/s. The upgrade of Jaguar XT5 to 37,376 six-core AMD Istanbul processors in 2009 increased performance 70 percent over that of its quad-core predecessor. Researchers anticipate that this unprecedented growth in computing capacity may help facilitate improved climate predictions, fuel-efficient engine designs, and the creation of advanced materials for energy production, transmission, and storage.
