A second Blue Gene/L supercomputer has posted speed results that lift it to the high ranks of supercomputing, IBM plans to announce Monday.
The system, called Blue Gene Watson and located at IBM's Thomas Watson Research Center, performed 91.3 trillion calculations per second, or 91.3 teraflops. That means it's second only to IBM's original Blue Gene/L system, the fastest supercomputer in the world, located at Lawrence Livermore National Laboratory and clocked at 135 teraflops.
IBM's Watson announcement will come two weeks before an expected bevy of such results, when researchers plan to release the latest list of the world's 500 fastest machines. The list is unveiled twice yearly at supercomputing conferences.
The higher speed, measured with an algebraic calculation test called Linpack, puts IBM another notch ahead of Silicon Graphics, whose Columbia system at NASA reached 51.9 teraflops last fall
