XT5 Cray, a supercomputer running a laboratory in the U.S. Oak Ridge, is currently the most powerful computing machine in the world. Jaguar, reaching 1.759 petaflopses computing power, finally dethroned IBM's Roadrunner supercomputer, the leader of the previous rankings.
This information will be confirmed on Tuesday, November 17, when will be officially published the latest edition of TOP500 list - updated twice a year a statement of computers the world's largest computing power. However, this will be just a formality, as the party Top500.org now provides key details of the new rating and the current statement - http://www.top500.org/lists/2009/11/press-release.

Compared with the previous, 33 editing list, Jaguar significantly improved performance - the computer's computing power has increased from 1.059 to 1.759 petaflopses (1 petaflops = 1 billiards floating point operations per second). This is the result of a major expansion of what the machine has undergone in recent times (increased number of AMD Opteron processors, making the total number of cores increased from 150 152 to 224 162).
Jaguar thus eventually overtook his rival under the sign of IBM - Roadrunner machine. The latter, launched in mid-2008 the U.S. Department of Energy laboratory in Los Alamos from a hit on the forehead TOP500 list - was the first such machine, which exceeded the barrier of 1 petaflops. In the June chart performance rating system was 1.059 petaflopses, but has since declined slightly - to 1.042 petaflopses - following its reconstruction.

On the third list - the sixth - was promoted another Cray XT5 system called Kraken, functioning at the University of Tennessee, in the local National Institute of Informatics. Its capacity is 832 teraflopses (trillion operations per second).

Americas "rule" ...

In the first "top ten" list were the only two systems outside the United States. One is BlueGene / P (JUGENE), built by IBM for the German center Forschungszentrum Juelich (825 teraflopses, 4th place). The second is the Tianhe-1, Chinese supercomputer using Intel Xeon and AMD's graphics processors. Is located in the city of Tianjin and the computing power reaches 563 teraflopses (5th place). America dominated the table - in the U.S. are up 277 of the 500 included in the supercomputers. In Europe work 153, and in Asia - 50 Machine.

As for the CPU vendors, Intel is governed on the list - 402 machines benefit from the CPU (this figure is 3 more than in the June ranking). The second is an IBM (52 systems), and the third - AMD (42 machines).

The majority of supercomputers - including 426 - use the quad-core processors. It is noteworthy that six machines are used in systems IBM Cell Broadband Engine. Remains the largest provider of supercomputers HP (210), followed by the 185 ranks IBM machines. However, the systems that other companies offer, including greater computing power.
