Cray XT5 Jaguar with AMD Opteron is fastest supercomputer

Monday, November 16, 2009, 13:14 by Tech Correspondent

AMD Cray XT5 ‘Jaguar’ has been named the fastest supercomputer at the Top 500 chip-speed measuring contest. The Cray XT5 Jaguar measured a speed 1.759 petaflops per second from its 224,162 cores.

One petaflop (floating point operations per second) is one quadrillion mathematical calculations. The last time the Top 500 supercomputer race was held, the Cray had narrowly lost to the Roadrunner supercomputer in speed. The closest is IBM Roadrunner, which has a processing speed of 1.04 petaflop. The wide difference in speed means that Cray XT5 Jaguar supercomputer with AMD process will be about 50% faster than the Roadrunner.

In layman’s language, this means that at the top speed, a Cray XT5 supercomputer with AMD Opteron six-core processor can complete the same work in 9 hours, for which a normal Intel laptop would take 2000 years.
Cray XT5 Jaguar with AMD Opteron processors beat IBM’s Roadrunner, which was the champion so far. The Top 500 contest is conducted twice every year. The last supercomputer race held in June 2008 was won by IBM’s Roadrunner.
Embarrassingly, the Intel series of supercomputer chips did not feature anywhere in the Top 10, except at No.5, where it debuted along with an AMD chip in a Chinese supercomputer.
After last year’s contest, the IBM Roadrunner was repartitioned, while the AMD Opteron processor was upgraded from quad-core to six-core. While the repartitioning affected the speed of the Roadrunner, the upgrade improved the Cray’s speed. Most of the supercomputers run the Linux operating system.
The Top 10 supercomputers on the Top 500 list this year are (1) Jaguar, Cray, Oak Ridge National Laboratory (1.75 petaflop/s) (2) Roadrunner, IBM, Los Alamos National Laboratory (1.04 petaflop/s) (3) Kraken XT5, Cray, National Institute for Computational Sciences (832 teraflop/s) (4) JUGENE, IBM, Forschungszentrum Juelich (825.5 teraflop/s)  (5) Tianhe-1, NUDT, National SuperComputer Center in Tianjin (563.1 teraflop/s) (6) Pleiades, SGI, NASA Ames Research Center (544.3 teraflop/s) (7) BlueGeneL, IBM, Lawrence Livermore National Laboratory (478.2 teraflop/s) (8) BlueGene/P, IBM, Argonne National Laboratory (458.61 teraflop/s) (9) Ranger, Sun, Texas Advanced Computing Center (433.20 teraflop/s) (10) Red Sky, Sun, Sandia National Laboratories (423.9 teraflop/s)
Most of the supercomputers which appeared in the speed race were housed in the US. The No.1 supercomputer Cray XT5 Jaguar was housed at the Oak Ridge National Laboratory in Tennessee. The Top 500 list is mostly made of HP and IBM supercomputers. Out of the 500 contestants, 210 were from HP and 185 from IBM.
Peter Ungaro, president and CEO of Cray said that While Cray is thrilled to have designed and built a supercomputing system that broke a number of firsts in the industry, the company is most proud of the fact that Jaguar is used day-in and day-out to solve real-world scientific problems at sustained speeds that no other system in the world can match. He said that this includes the first two scientific applications in the world ever to break one petaflops in sustained performance.”
The official announcement of the winner – Cray XT5 Jaguar with AMD – will be tomorrow (Tuesday) at Oregon.
