Intel and Cray Team

Early supercomputer developer Cray said today that it was working with Intel for mutual help on advancing supercomputers. The teamwork will see Cray help Intel develop the technology for clusters as well as to improve the in-processor technology, such as newer generations of multi-core processors. In return, Cray will make its first use Intel's processors for its own supercomputers, replacing AMD Opterons and more specialized supercomputer chips.
