Chinese websites are claiming the country has overtaken the US as the home of the world’s fastest 'supercomputer.' The official result is scheduled to be announced next week. The rankings in question are the TOP500 project, which has published a list twice a year since 1993. It measures the maximum speed achieved in a standard test, with tiebreaks decided by the theoretical peak.

The current number one ranked machine is named Jaguar, a Cray XT5 system housed at the Oak Ridge National Laboratory in 2009. It’s been in the top spot for a year and achieved that position with a speed of 1.759 petaflops (1,759 trillion calculations per second.) but now reports from China claim a machine named Tianhe-1 (which means Milky Way) is number one in that country. It’s said to have achieved a sustained processing speed of 2.507 petaflops, blowing away Jaguar. While the next TOP-500 rankings period doesn’t close until Sunday it appears that, if the figures are correct and verified, there’s virtually no chance of a rival machine beating the achievement.

PS This has become true for me too.
