The new machine, >the Sunway BlueLight MPP, was installed in September at the National >Supercomputer Center in Jinan, the capital of Shandong Province in eastern >China. > >The Sunway system, which can perform about 1,000 trillion calculations per >second — a petaflop — will probably rank among the 20 fastest computers in the >world. More significantly, it is composed of 8,700 ShenWei SW1600 >microprocessors, designed at a Chinese computer institute and manufactured in >Shanghai. > >Currently, the Chinese are about three generations behind the state-of-art >chip making technologies used by world leaders such as the United States, >South Korea, Japan and Taiwan. > >“This is a bit of a surprise,” said Jack Dongarra, a computer scientist at the >University of Tennessee and a leader of the Top500 project, a list of the >world’s fastest computers. > >Last fall, another Chinese-based supercomputer, the Tianhe-1A, created an >international sensation when it was briefly ranked as the world’s fastest, >before it was displaced in the spring by a rival Japanese machine, the K >Computer, designed by Fujitsu. But the Tianhe was built from processor chips >made by American companies, Intel and Nvidia, though its internal switching >system was designed by Chinese engineers. Similarly, the K computer was based >on Sparc chips, originally designed at Sun Microsystems in Silicon Valley. > >Dr. Dongarra said the Sunway’s theoretical peak performance was about 74 >percent as fast as the fastest United States computer — the Jaguar >supercomputer at the Department of Energy facility at Oak Ridge National >Laboratory, made by Cray Inc. That machine is currently the third fastest on >the list. > >The Energy Department is planning three supercomputers that would run at 10 to >20 petaflops. And the United States is embarking on an effort to reach an >exaflop, or one million trillion mathematical operations in a second, sometime >before the end of the decade, though most computer scientists say the >necessary technologies do not yet exist. > >To build such a computer from existing components would require immense >amounts of electricity — roughly the amount produced by a medium-size nuclear >power plant. In contrast, Dr. Dongarra said it was intriguing that the power >requirements of the new Chinese supercomputer were relatively modest — about >one megawatt, according to reports from the technical conference. The Tianhe >supercomputer consumes about four megawatts and the Jaguar about seven. > >The ShenWei microprocessor appears to be based on some of the same design >principles that are favored by Intel’s most advanced microprocessors, >according to several supercomputer experts in the United States. > >But there is disagreement over whether the machine’s cooling technology is >appropriate for designs that will be required by the exaflop-class >supercomputers of the future. > >Photos of the new Sunway supercomputer reveal an elaborate water-cooling >system that may be a significant advance in the design of the very fastest >machines. “Getting this cooling technology correct is very, very difficult,” >said Steven Wallach, chief scientist at Convey Computer, a Richardson, Tex., >supercomputer firm. “This tells me that this is a serious design. This cooling >technology could scale to exaflop. They are in the hunt to win.” > >[Non-text portions of this message have been removed] > > > > > [Non-text portions of this message have been removed] ------------------------------------ Post message: [email protected] Subscribe : [email protected] Unsubscribe : [email protected] List owner : [email protected] Homepage : http://proletar.8m.com/Yahoo!
