Seymour Roger Cray (September 28, 1925 [1] – October 5, 1996 [2]) was an American electrical engineer and supercomputer architect who designed a series of computers that were the fastest in the world for decades, and founded Cray Research, which built many of these machines.
Cray-2 supercomputer. When CDC ran into financial difficulties in the late 1960s, development funds for Cray's follow-on CDC 8600 became scarce. When he was told the project would have to be put "on hold" in 1972, Cray left to form his own company, Cray Research, Inc. Copying the previous arrangement, Cray kept the research and development facilities in Chippewa Falls, and put the business ...
The Cray XC30 is a massively parallel multiprocessor supercomputer manufactured by Cray.It consists of Intel Xeon processors, with optional Nvidia Tesla or Xeon Phi accelerators, connected together by Cray's proprietary "Aries" interconnect, stored in air-cooled or liquid-cooled cabinets. [1]
A personal supercomputer (PSC) is a marketing ploy used by computer manufacturers for high-performance computer systems and was a popular term in the mid 2000s to early 2010s. [1] There is no exact definition for what a personal supercomputer is. Many systems have had that label put on them like the Cray CX1 [2] and the Apple Power Mac G4. [3]
The Cray XC50 is a massively parallel multiprocessor supercomputer manufactured by Cray. [1] The machine can support Intel Xeon processors, as well as Cavium ThunderX2 processors, Xeon Phi processors and NVIDIA Tesla P100 GPUs. [2] The processors are connected by Cray's proprietary "Aries" interconnect, in a dragonfly network topology. [1]
The Cray T3E was Cray Research's second-generation massively parallel supercomputer architecture, launched in late November 1995. The first T3E was installed at the Pittsburgh Supercomputing Center in 1996. Like the previous Cray T3D, it was a fully distributed memory machine using a 3D torus topology interconnection network.
XC40 cabinet (front) with 48 blades in groups of 16, each blade containing 4 nodes. The Cray XC40 is a massively parallel multiprocessor supercomputer manufactured by Cray.It consists of Intel Haswell Xeon processors, with optional Nvidia Tesla or Intel Xeon Phi accelerators, connected together by Cray's proprietary "Aries" interconnect, stored in air-cooled or liquid-cooled cabinets.

The Cray C90 series (initially named the Y-MP C90) was a vector processor supercomputer launched by Cray Research in 1991. The C90 was a development of the Cray Y-MP architecture. Compared to the Y-MP, the C90 processor had a dual vector pipeline and a faster 4.1 ns clock cycle (244 MHz), which together gave three times the performance of the Y ...
