Cray XC30

• The Swedish Royal Institute of Technology has a XC30 system. The system has a four year budget of SEK 170 million.[6]
• The UK's national high-performance computing facility in Edinburgh has a 118,080-core XC30 called "ARCHER,"[7] which cost £43 million.[8]
• There is a 115,984-core XC30 system called "Piz Daint" at the Swiss National Supercomputing Centre, located in southern Switzerland.[9]
• The ECMWF also uses two XC30 to predict the weather.[10]
• The Deutscher Wetterdienst has two XC30s (for redundancy), also used for weather prediction.[11]
• The Danish Meteorological Institute operates a dual XC30 (located at the Icelandic Meteorological Office due to cheaper cooling and electricity). The same supercomputer is used by Iceland to predict national and surrounding weather.[12]

The Center for Computational Astrophysics at the National Astronomical Observatory of Japan had a XC30 system named "ATERUI".[13] This was upgraded to a Cray XC40 system.[13]

• The NERSC has a 133,824-core XC30 called "Edison."[14]
• A 225,984-core XC30 system is installed at an undisclosed government location.[15]
• The Air Force Research Laboratory has an XC30 called "Lightning."[16]
• The US Naval Academy has an XC30 hosted at the University of Maryland Institute for Advanced Computer Studies, named "Grace" after Rear Admiral Grace Hopper.[17]

• The Pawsey Supercomputing Centre 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.[18]
