c|net - "Cray on Monday is expected to announce two supercomputing developments, the new AMD Opteron-based XT4 shipping this year and the multi-threaded XMT due next year. The two machines are two components of Cray's longer-term "Ranier" plan to converge its four disparate product lines into a single family. Indeed, the Opteron-based XT4 merges two existing lines, and the XMT itself is a variant of the XT4. The company plans to announce the systems at the SC06 supercomputing show in Tampa, Fla. The convergence plan is part of Cray's effort to create a design whose varied hardware will adapt to different types of computing chores. The company's plan is already well under way, but full convergence won't happen unless Cray wins funding in the U.S. government's Defense Advanced Research and Development Agency (DARPA) supercomputing challenge.
The new Opteron system combines technology from the company's XT3 design, initially developed for Sandia National Laboratories' Red Storm supercomputer, and the XD1 systems from Cray's acquisition of OctigaBay, said Jan Silverman, senior vice president of corporate strategy. "
