Cray Legacy Products (No Longer in Production)

Cray X1E Supercomputer

The Cray X1E™ supercomputer combined the processor performance of traditional vector systems with the scalability of microprocessor-based architectures. High performance interconnect and memory subsystems allowed the Cray X1E system to scale from 16 to 8,192 processors, delivering up to 147 TFLOPS in a single system. The Cray X1E supercomputer and its predecessor, the Cray X1™ supercomputer, were the first vector systems designed to scale to thousands of processors in a single system image.

Cray XD1 Supercomputer

The Cray XD1™ supercomputer, introduced in 2004, was designed around a direct-connect processor approach to massively parallel processing that directly linked together processors, alleviating memory contention and interconnect bottlenecks found in cluster and SMP systems.

The Cray XD1 system embedded a high speed interconnect and application accelerators to remove major bottlenecks and improve performance on real-world applications. It was designed to meet the requirements of highly demanding HPC applications in fields ranging from product design to weather prediction to scientific research, to enable faster simulation and analysis, solve complex problems, and bring solutions to market sooner.

Cray SV1 and SV1ex™ Supercomputers

The Cray SV1 and Cray SV1ex vector supercomputing systems, introduced in 1998 and 2001, offered innovations in vector cache, MSP (Multi-Streaming Processor), and integrated SSD (Solid State Disk). Each system included a UNICOS operating system, software environment compatible with a variety of highly-tuned UNICOS applications, and CF90™ Fortran compiler that provided automatic vectorization, scalar optimization, and Autotasking™, a parallel-processing feature allowing programmers to partition individual programs so that the parts execute simultaneously on multiple processors.
