The World’s most powerful supercomputer

A Cray Supercomputer at Oak Ridge National Laboratory has just regained the title of “World’s Most Powerful Supercomputer”.

This upgraded Jaguar Supercomputer at Oak Ridge in Tennessee is capable of delivering 1.759 petaflops per second from the 224,162 cores onboard. A Petaflop is one thousand trillion calculations per second.

The list of the 500 top supercomputers is due to be released today at the SC09 supercomputing conference in Portland, Oregan and it is put together twice a year with the overall scores of all systems in the list hitting 27.6 petaflops – almost enough to help handle Crysis Warhead at 2560×1600 on enthusiast settings.

Jaguar was in second place for a while and recently underwent some processor upgrades which allowed it to take the lead. It is based on the Cray XT5 Linux supercomputer platform which uses AMD processors at the heart of the beast. We reported a while ago on China’s fastest supercomputer ever to hit the market, The Tianhe-1 achieves 563 teraflops per cent for the No.5 ranking – it uses Intel Xeon processors with AMD/ATI graphics cards as accelerators – each node of the 71,680 core system has two Intel processors running with two AMD GPUs (4870 X2’s).

Intel processors power 402 of the systems on the top 500, which translates to around 80.4 percent, up from 399 in June of this year. Almost all of the systems on the list (426) are now using quad core processors.
