Just seven miles south of our OSTI facility in Oak Ridge, Tennessee is a national treasure – the Oak Ridge National Laboratory (ORNL). ORNL is DOE’s largest multi-program laboratory where remarkable scientific expertise and world-class scientific facilities and equipment are applied to develop scientific and technological solutions that are changing our world. ORNL’s National Center for Computational Sciences is home to two of ORNL’s high-performance computing projects -- the National Climate-Computing Research Center (NCRC), where research is dedicated to climate science, and the Oak Ridge Leadership Computing Facility (OLCF). OLCF delivers the most powerful computational resource in the U.S. for open science, allowing the world’s best computational researchers an opportunity to tackle problems that would be unthinkable on other systems.
OLCF has such a remarkable history. It was established in 2004 to deliver a supercomputer 100 times more powerful than the leading systems of the day. Its Cray XT4 Jaguar ran the first scientific applications to exceed 1,000 trillion calculations a second (1 petaflop) in 2008. In preparation for the exascale, OLCF elicited petascale computational science requirements from the international science community and began to prepare for next-generation science. OLCF continued to expand the limits of the Jaguar in 2011 to deliver a peak performance of more than 2.3 petaflops becoming the world’s most powerful supercomputer. OLCF has now upgraded the Jaguar to...Read more...
