Submission + - BlueGene/L ranked 1st in top500 for the 4th time
paleshadows writes: The top500 list ranks the top 500 most powerful supercomputers in the world. It is published semiannually since 1993. The new list indicates that, for the fourth straight time, IBM's BlueGene/L of LLNL claimed the No. 1 spot at ~281 TerFlops per second. But while the No. 1 is still unchallenged, the list shows a lot of shuffling and the largest turnover among list entries in the history of the top500 project. This graph enumerates the number of systems each vendor has within the list, indicating that IBM is the dominant player, but that HP rapidly closes the gap. Of the top 10, the first 8 are situated in the U.S., while No. 9 and 10 are populated by Spain and Germany, respectively. Japan's first entry is at No. 14 with the EarthSimulator, which ranked first until 2004 when it was knocked off the top by the first blue BlueGene/L system.
