Computers & Technology: Cray XT5 Jaguar bests IBM Roadrunner as world's fastest supercomputer
Tags: Fastest, IBM, Roadrunner, supercomputer
The lead position on ORNLs Top 500 Supercomputer list is now Crays XT5 Jaguar supercomputer, besting IBMs Roadrunner.
The XT5 Jaguar, located at Oak Ridge National Lab in Tennessee, recently received a refresh that included upgrading its quad-core CPUs to hex-core Opteron processors. That means a 2.3 petaflop per second theoretical performance peak (nearly a quarter of a million cores), and 1.75 petaflops measured by the Linpack benchmark.

Electronics: Worlds Fastest Camera: Shutter Speed Half a Billionth of a Second
The Steam camera not only shoots images just 440 trillionths of a second in length, it can rack up an astonishing six million of them in a single second.
How does it work this magic? Lasers, of course, the answer to all scientific problems. The Steam (Serial Time-Encoded Amplified iMaging) doesnt have a physical shutter, instead relying on a pulse of light to freeze time, much like a standard camera flash will freeze a bullet hitting a balloon.
