-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 According to the NYT the new Top500 list (due out in the next few hours) will list the Japanese 'K' machine at the #1 spot at 8.2 PF.
http://www.nytimes.com/2011/06/20/technology/20computer.html?_r=1 # The computer, known as "K Computer", is three times # faster than a Chinese rival that previously held the # top position, said Jack Dongarra, a professor of # electrical engineering and computer science at the # University of Tennessee at Knoxville who keeps the # official rankings of computer performance. [...] # K is made up of 672 cabinets filled with system # boards. Although considered energy-efficient, it # still uses enough electricity to power nearly # 10,000 homes at a cost of around $10 million # annually, Mr. Dongarra said. # # The research lab that houses K plans to increase # the computer?s size to 800 cabinets. That will # raise its speed, which already exceeds that of its # five closest competitors combined, Mr. Dongarra said. The excellent @HPC_Guru on Twitter said: # K Supercomputer Technical details: 80k+ SPARC64 VIIIfx # CPUs, 640K+ cores, 1PB+ RAM, 6-dimensional Mesh/Torus # interconnect But I have a reliable source who claims that this is using GRAPE cards as APUs to reach its performance without causing (another) meltdown in Japan.. cheers, Chris - -- Christopher Samuel - Senior Systems Administrator VLSCI - Victorian Life Sciences Computation Initiative Email: sam...@unimelb.edu.au Phone: +61 (0)3 903 55545 http://www.vlsci.unimelb.edu.au/ -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk3+824ACgkQO2KABBYQAh/HsQCcD1eNOe9hPG6BohYWWJ7IU74f SJAAoICP4/FOR7BSISMMI8QODOM8OHVR =V8Lo -----END PGP SIGNATURE----- _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org sponsored by Penguin Computing To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
