The computer giant’s BlueGene/L system, developed with the Department of Energy's National Nuclear Security Administration and installed at Lawrence Livermore National Laboratory, heads the list with a performance of 280.6 teraflops - or trillions of calculations - per second.
IBM systems accounted for 237 of the 500 most powerful supercomputers and nearly half of the total processing power on the list, which was released at the SC06 high performance computing conference in Florida.
Sandia National Laboratories’ Cray Red Storm supercomputer is number two in the rankings and is only the second system ever to top the 100 Tflops/s mark with a performance measured at 101.4 Tflops/s.
IBM eServer Blue Gene Solution system, installed at the company’s Thomas Watson Research Centre, came in third with 91.20 Tflops/s performance.
