Cray XC30

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. Each liquid-cooled cabinet can contain up to 48 blades, each with eight CPU sockets, and uses 90 kW of power. The XC series supercomputers are available with the Cray DataWarp applications I/O accelerator technology.

In 2014, Cray XC30 systems appear prominently on the TOP500 Supercomputer lists.

Deployed Cray XC30 systems

Europe

• The UK's national high-performance computing facility in Edinburgh has a 118,080-core XC30 called "ARCHER," which cost £43 million.
• There is a 115,984-core XC30 system called "Piz Daint" at the Swiss National Supercomputing Centre, located in southern Switzerland.
• The ECMWF has two XC30 systems used for weather prediction.
• The Deutscher Wetterdienst has two XC30s (for redundancy), also used for weather prediction.
• The Danish Meteorological Institute operates a dual XC30 (located at the Icelandic Meteorological Office due to cheaper electricity).

United States

• The NERSC has a 133,824-core XC30 called "Edison."
• A 225,984-core XC30 system is installed at an undisclosed government location.
• The Air Force Research Laboratory has an XC30 called "Lightning."

Australia

• iVEC has a 9,440-core XC30 called "Galaxy." One chassis of this contains GPUs; the rest is all-CPU. Its November 2013 and June 2014 Top500 entries were before the GPU chassis was installed. This system is used for radio astronomy.
