Around the world, scientists and engineers in industry, government and academia rely on Cray to power their high performance computing applications. Cray combines computing systems purpose-built to meet the specific needs of high performance applications with expertise in a broad range of HPC fields to provide a total solution to customers' HPC needs. Only Cray is fully dedicated to providing superior computational power to scientists and engineers in government, academia and industry, allowing customers to excel in real-world applications.

Cray serves a technical and scientific user community where sustained performance, not merely theoretical peak performance, is the relevant benchmark. Cray's leadership in creating innovative products and services is driven by growing customer requirements for leadership-class scientific research tools, advanced design capabilities for individual scientific/technical users, and tools that deliver superior value and performance to all HPC users.

The next revolution in scalable computing, the Cray XT5™ system combines unprecedented scalability with exceptional manageability, lower cost of ownership, and broader application support. And, as the foundation for the Cray XT5h™ — the industry's most integrated hybrid supercomputer — it creates a new paradigm in high performance computing by combining industry-leading scalar processing capability with high bandwidth vector processing, reconfigurable FPGA hardware acceleration and alternative parallel programming languages in a single system.

Building on the success of the Cray XT3™ system, the Cray XT4™ system brings new levels of scalability and sustained performance to high performance computing (HPC). Engineered to meet the demanding needs of capability class HPC applications, each feature and function is selected in order to enable larger problems, faster solutions, and a greater return on investment. Designed to support the most challenging HPC workloads, the Cray XT4 supercomputer delivers scalable power for the toughest computing challenges. Every aspect of the Cray XT4 and Cray XT3 systems is engineered to deliver superior performance for massively parallel applications.

The Cray XMT™ supercomputing system is a scalable massively multithreaded platform with a shared memory architecture for large-scale data analysis and data mining. The system is purpose-built for parallel applications that are dynamically changing, require random access to shared memory and typically do not run well on conventional systems. Multithreaded technology is ideally suited for tasks such as pattern matching, scenario development, behavioral prediction, anomaly identification and graph analysis.
