The Jaguar Supercomputer, a Cray XT5 system, at the Department of Energy’s Oak Ridge National Laboratory has just undergone an upgrade that puts it ahead of IBM’s Roadrunner to make it the world’s fastest supercomputer. The machine has a peak speed of 2.33 petaflops (over two thousand trillion calculations per second). The new speed was achieved through an upgrade from four-core to six-core processors that was funded by a $19.9 million grant from the National Science Foundation.
Eighty percent of Jaguar’s resources are allocated through the Innovative and Novel Computational Impact on Theory and Experiment (INCITE) program, which is a competitive peer reviewed process open to researchers from universities, industry, government and non-profit organizations. Over the past year scientific teams made breakthrough discoveries in climate science, chemistry, materials science, nuclear energy, physics, bioenergy, astrophysics, geosciences, fusion, and combustion. The research included high-resolutioin climate models, and in-depth studies about impediments to producing bioethanol from plant material.
