Homegrown interconnect pushes China super to No. 1 on Top 500 list

摘要

A DOMESTICALLY DEVELOPED, ultrafast interconnect chip set was part of the secret sauce behind China's Tianhe-ia, the first Chinese-built system to be named the world's fastest supercomputer. The 160-Gbit/second Galaxy interconnect links thousands of the latest Intel Westmere and Nvidia Fermi processors in the system, which will be used for scientific research. The Tianhe-ia, installed at the National Supercomputing Center in Tianjin, was measured at 2.5 petaflops in October using the Linpack benchmark. It is expected to rank first on
