Cray XT4™ Systems With New Quad-Core AMD Opteron™ Processor to Provide Petaflops Capability

SEATTLE, WA--(Marketwire - September 10, 2007) - Global supercomputer leader Cray Inc. (NASDAQ: CRAY) today reported that it expects to begin shipping its industry-leading Cray XT4™ systems with new, ultra-powerful Quad-Core AMD Opteron™ processors by year-end. The company has already received significant orders for these enhanced quad-core systems, including orders from the Department of Energy's Oak Ridge National Laboratory, CSC Finland, Engineer Research and Development Center for the US Army Corps of Engineers and the UK's Engineering and Physical Sciences Research Council for the HECToR national academic service.

"Our customers are already achieving breakthrough results with the Cray XT4 system and quad-core technology will allow them to solve more complex problems faster, doing more accurate simulations," said Peter Ungaro, president and CEO of Cray. "The Cray XT4 system was designed with quad-core performance in mind and we have seen early examples of excellent scalability and sustained performance with Quad-Core AMD Opteron processors and our advanced Cray SeaStar™ interconnect network. Quad-core will give new customers a big boost in performance and a substantial total cost of ownership win. It will do the same for our current customers at a low incremental cost, extending the useful life of their existing Cray XT3™ and XT4 systems."

The Cray XT4 system is a massively parallel processor (MPP) system that provides unrivaled sustained performance by balancing performance between powerful processors, memory, interconnect, and IO. Both hardware and software are designed to scale to more than 120,000 processor cores and over one petaflops of peak performance. Both the Cray XT3 and Cray XT4 systems can be upgraded to Cray XT4 systems with quad-core support.

"We upgraded from single-core to dual-core in the field very smoothly, and we anticipate being able to do the same with the Cray XT4 system with quad-core support," said Buddy Bland, Project Director of the Leadership Computing Facility at Oak Ridge National Laboratory. "We are already running machines with 23,000 processor cores, and we have high expectations about our impending quad-core delivery."

"The combination of Cray's innovative supercomputing expertise and AMD's revolutionary native multi-core technology and Direct Connect Architecture has made tremendous contributions to the supercomputing industry," said Randy Allen, corporate vice president and general manager, Server and Workstation Division, AMD (NYSE: AMD). "With the superior performance, memory scalability and overall system efficiency of the Quad-Core AMD Opteron processor, AMD64 technology continues to be an integral component of Cray's successful MPP product line."

About Quad-Core AMD Opteron Processor

More than just four cores, Quad-Core AMD Opteron processors feature Direct Connect Architecture, which means processors are directly connected to one another, and the I/O and memory subsystem are also directly connected to the processor, helping reduce bottlenecks for better performance. Quad-Core AMD Opteron processors are not only the industry's first native quad-core processors, they are also the first native quad-core processors designed to operate within the same socket and thermal envelopes as AMD's current generation of dual-core processors.

About the Cray XT4 Supercomputer

Building on the success of the Cray XT3 system, the Cray XT4 is an MPP supercomputer purpose-built to deliver exceptional sustained application performance for challenging scientific and engineering problems. The supercomputer's high-speed 3D torus interconnect, advanced MPP operating system and high-speed global input/output make it possible for users to scale applications to more than 120,000 processor cores with exceptional sustained performance. The system's scalable processing element uses x86 64-bit AMD Opteron processors that employ HyperTransport™ technology to increase bandwidth and reduce latency. Go to for more information.
