Dank an "Daemon Zweiter Ordnung", dass er nochmal die Historie des VT
Clusters aufgeschrieben hat:
http://www.heise.de/newsticker/foren/go.shtml?read=1&msg_id=6747804&forum_id=67889
Es ist ein offenes Geheimnis, dass der VT Cluster nie wegen
Stabilitätsproblemen trotz aller Ankündigungen nie den Praxisbetrieb
aufgenommen hat und letzendlich für 9 Monate komplett abgeschaltet
wurde (und damit aus den Top500 geflogen ist). Wenn man nach "Daemon"
als Preis für eine Stunde Rechenzeit 1$/CPU ansetzt, kommt man auf
300 Tage * 24 Std. * 2200 CPUs * 1 $ = 15,8 Mio Dollar
Schaden.
Super Leistung! Das relativiert den Preis des Clusters doch
erheblich.
Auch in der Scientific Compunting Community sieht man den Terascale
Cluster als Papiertiger, der erst einmal seine Leistung beweisen muß:
"The Virginia Tech system has attracted considerable media attention,
but some supercomputer users say that Apple has yet to prove that its
computers can do more in high-performance computing than run
benchmarks.
"All I've seen are Linpack benchmarks, and that's not why we buy
computers," said Scott Studham, manager of computer operations at the
Pacific Northwest National Laboratory's Molecular Science Computing
Facility. "The science impacts of these systems still haven't been
demonstrated, and the fact that they disappeared from the most recent
Top500 list tells me that the first system didn't work or it was put
together solely for Linpacking, which isn't a useful measure of a
supercomputer."
Though the Xserve G5 shows a lot of promise, the fact that the
Virginia Tech system has been down for several months raises
questions about Apple's ability to migrate customers to new
high-performance computing systems, said Jeff Nichols, a director in
the computer science and math division at Oak Ridge National
Laboratory. "They really made a mistake by not having the machine
there throughout the procurement of the follow-up system," he said.
"When a machine disappears for three or four months, then that's a
bad thing." "

Das ist alles doch sehr, sehr peinlich.
