Wolfgang Gruener writes that an IBM patent filing reveals plans for a 100 Petaflop supercomputer follow-on to Sequoia. With 8.4 million compute cores, the system will consume almost 16 MW.
IBM is well on its way to achieve the next milestone in supercomputing: BlueGene/Q is estimated to hit a peak performance of 20 Pflop/s, when it will go into operation as “Sequoia” supercomputer at the Lawrence Livermore National Laboratory in 2012. However, its architecture is now described in a patent that lifts the compute performance to 107 PFlop/s. This would be about 12 times the compute horsepower that is posted by K computer, a Japanese system that claimed the top spot in the Top500 ranking back in June with a peak performance of 8.8 PFlop/s. Five years ago, the industry-leading system was BlueGene/L, which stood at just 280.6 TFlop/s. If IBM’s calculations are correct, then this new BlueGene/Q-based system could be 381 times faster than BlueGene/L.
