Dual-Core AMD Opteron processors will be available as an option on Cray XD1 and Cray XT3 supercomputers later in 2005.
AMD's 32 and 64-bit technology fits two processor cores on a single die, which the company reports doubles processing capacity in the same amount of space with minimal increase in power consumption and heat levels. The Crays' system architectures speed high-performance computing by directly linking processors, memory, and I/O resources instead of using a conventional PCI bus. These architectures ensure that sophisticated software can exploit all available processing power as more processors are added to the system.
