There has been quite a bit of shuffling around in the latest edition of the Top 500 supercomputers in the world. The full list has been published along with a press release covering the changes to the top 10. For a play by play report, check the highlights. Of note are the presence of two new IBM clusters in the top 10.
The Earth Simulator is still number one, though both IBM and HP have quite an impressive showing near the top. California Digital has put together an impressive cluster at #2. Missing from the list is the G5 cluster at Virginia Tech, which was offline during this survey for a hardware upgrade. Hopefully it’ll pop back on the charts next time.
