With much anticipated fanfare, the Top500 Supercomputer list was announced last week at the International Supercomputing Conference in Dresden, Germany.

For the fourth time, the BlueGene/L System development by IBM and DOE’s National Nuclear Security Administration that is installed at DOE’s Lawrence Livermore National Laboratory claimed the No. 1 spot with a Linpack benchmark performance of 280.6 TFlop/sec. The second- and third-placed systems also exceeded 100 TFlop/sec: the upgraded Cray XT4/XT3 at DOE’s Oak Ridge National Laboratory, with a benchmark performance of 101.7 TFlop/sec, and Sandia National Laboratory’s Cray Red Storm system, rated 101.4 TFlop/sec. Dell’s Abe system at NCSA, built on 1,200 PowerEdge blades, ranked number 8 overall; the highest performing blade solution. IBM’s MareNostrum supercomputer, built on IBM BladeCenter JS21 blade servers, ranked number 9 on the overall list to retain its position as the most powerful supercomputer in Europe. The performance value required to make it onto the list increased to 4.005 TFlop/sec on the Linpack benchmark, compared with 2.737 TFlop/s six months ago. The system ranked #500 on the current list would have held position #216 just six months earlier. This is the largest turnover between lists in the TOP500 project’s fifteen-year history.

Very cool, it’s always interesting to see what technologies have been put together to provide a ‘super computer’ in this case we see i ranges from the Cray Red Storm system, to an array of Dell PowerEdge blades, and some IBM BladeCenter JS21′s check it out.
