A supercomputer on 562 Intel Xeons finished in China
Having installed successfully in Nov. 2004 a GT1000 Supercomputing Blade System (1 Teraflops) at Beijing Biomedical Research Institute, Galactic Computing just completed another GT4000 Supercomputing Blade System (281 blades, 562 Intel Xeon processors) which has attained the world rank of 100 according to the 2005 June 22nd release of Top500 supercomputers list. The peak performance of the entire system is 4.046 Teraflops and the HPLinpack performance is 3.413 Teraflops which corresponds to the efficiency of 84.35%.
GT4000 result demonstrates the highest HPLinpack efficiency in the world among teraflop s scale supercomputers based on x86 processors which have been announced to date.
Also, this is the one and only supercomputer in China with completely embedded end-to-end InfiniBand 10Gb from blade-to-blade and blade-to-storage with 4 microseconds latency (instead of 50 milliseconds as most 1Gb Ethernet networked server clusters) and can achieve storage data throughput rate up to 820MB/s (two to three times faster and yet cheaper than Fiber Channel SAN).
