AMD said that the Japanese T2K supercomputer has started number crunching using quad core Opterons it supplied.

The T2K computer is a joint development by Tokyo University, Kyoto University and the University of Tsukuba.

The machine delivers a theoretic max performance of around 140 teraflops and consists of 952 nodes of the Hitachi HA800-TC/RS425 technical server with four quad core AMD Opterons in each node.

Cray built the system in Tokyo, which is linked to the Kyoto Fujitsu HX600 HPC server. X
