Tue, 13 Nov 2012 13:29:24 EDT http://www.ornl.gov/info/ornlreview/v45_3_12/article03a.shtml Titan will combine two very different types of processors and will require users to adapt their applications accordingly. Tue, 13 Nov 2012 13:29:24 EDT http://www.ornl.gov/info/ornlreview/v45_3_12/article03b.shtml ORNL's Center for Accelerated Application Readiness is working with six world-class applications that to show how Titan's combination of GPUs and CPUs can revolutionize computational science. Tue, 13 Nov 2012 13:29:24 EDT http://www.ornl.gov/info/ornlreview/v45_3_12/article04.shtml Titan's computational prowess rests on tens of thousands of next-generation processors, each of which contains hundreds of cores designed to rip through calculations. Tue, 13 Nov 2012 13:29:24 EDT http://www.ornl.gov/info/ornlreview/v45_3_12/article05.shtml Some people would call Tom Evans an optimist. He's building a mathematical model of a nuclear reactor so detailed that the only computer it can run on hasn't been built yet. Tue, 13 Nov 2012 13:29:24 EDT http://www.ornl.gov/info/ornlreview/v45_3_12/article06.shtml Computational biophysicist Jeremy Smith specializes in performing science at the intersection of multiple disciplines. Tue, 13 Nov 2012 13:29:24 EDT http://www.ornl.gov/info/ornlreview/v45_3_12/article07.shtml Thanks to the digital revolution, the information available on any given topic has morphed from a sporadic stream of text and photos into a nonstop maelstrom of multimedia shrapnel. Tue, 13 Nov 2012 13:29:24 EDT http://www.ornl.gov/info/ornlreview/v45_3_12/article08.shtml Using ORNL's Jaguar supercomputer to capture glimpses of Earth's future, researchers are trying to bridge the gap between science and public policy. Tue, 13 Nov 2012 13:29:24 EDT http://www.ornl.gov/info/ornlreview/v45_3_12/article09.shtml Metallurgy is a very old subject, so you might think that by this point we would understand everything about it. That's not the case. Tue, 13 Nov 2012 13:29:24 EDT http://www.ornl.gov/info/ornlreview/v45_3_12/article10.shtml Jeff Nichols shares share his thoughts on how supercomputing impacts both R&D and day-to-day living. Tue, 13 Nov 2012 13:29:24 EDT http://www.ornl.gov/info/ornlreview/v45_3_12/article11.shtml Oxygen-23 exists at the edge of the nuclear landscape, where isotopes are fleeting and most commonly found within exploding stars. Tue, 13 Nov 2012 13:29:24 EDT http://www.ornl.gov/info/ornlreview/v45_3_12/article12.shtml An ORNL and University of Tennessee team has used the Jaguar supercomputer to calculate the number of isotopes allowed by the laws of physics.
