An updated list of world's fastest supercomputers has been released. The fastest of the pack are powered by IBM chips but Intel processors are in 64% of the computers on the list - the highest it ever had.
Rival AMD has its chips in 16% of the top 500 supercomputers, down from 21% a half year ago.
The list, published twice a year by academic researchers, once again was topped by an IBM Corp. supercomputer in the Lawrence Livermore national nuclear lab. The BlueGene/L system, as it is known, was recently upgraded and showed the ability to perform at 478 teraflops _ 478 trillion calculations per second.
That's tens of thousands of times faster than your average desktop PC today.
The No. 2 performer was an IBM supercomputer in a German research center that came in at 167 teraflops. No. 3 was a 127-teraflop system made by Silicon Graphics Inc. for the New Mexico Computing Applications Center.
For the first time, India placed a machine in the top 10: a 118-teraflop Hewlett-Packard Co. system in a research center run by Tata Sons Ltd. in Pune, India.
IBM accounted for 46 percent of the computers on the list, while HP had 33 percent. That reversed the standing on the last list, in June, when HP became the leading manufacturer in the top 500.
