The two-year reign of the massive Earth Simulator as the fastest supercomputer in the world appears to be nearing an end.
IBM executives on Wednesday will announce that one of the new machines in its Blue Gene project earlier this month reached a sustained peak of 36.01 trillion calculations per secondóor 36.01 teraflopsóduring internal tests in the company's laboratory in Rochester, Minn.
That peak bested the 35.86 teraflops reached by the 5,120-processor Earth Simulator computer, built by NEC Corp. and housed in Yokohama, Japan. IBM has sent the results to the Top500 organization, which twice a year releases a list of the top 500 computers in the world, said David Turek, vice president of IBM's Deep Computing unit.
The tests were conducted using an industry-standard benchmark, called LinPack, Turek said.........
That systemówhich will have more than 64,000 dual-processor compute nodes housed in 64 racksówill reach a peak of 360 teraflops. That system is scheduled to be completed by May 2005.
