The XC30 is a massively parallel multiprocessor supercomputer platform created by Cray and announced on November 8, 2012 [1] . During development, it was known as the Cascade project. This is the first representative of Cray supercomputers, based on Intel Xeon processors and the third, based on hybrid technologies, where Nvidia Tesla graphics processors or Xeon Phi compute processors are used for computing along with CPUs .
The XC30 platform is used in supercomputers of the US Government and the Swiss National Supercomputer Center (CSCS) [2] , which occupy 10th and 6th places, respectively, for June 2014 in the world ranking of Top500 supercomputers.

Description
Each Cray XC30 rack includes up to 384 Intel Xeon E5-2600 processors , or, since October 2013, Intel Xeon E5-2600 V2 [3] . Structurally, the rack contains three blade chassis, 16 blades each. In turn, each blade contains four dual-processor computing nodes. The node can be installed from 32 to 128 GB of memory with a bandwidth of up to 117 GB / s. Cooling water. [four]
For communication between nodes, the developed Cray interconnect bus Aries is used. Each port supports a bandwidth of 12 Gb / s with an optical connection between the groups and 14 Gb / s with an electrical connection within the groups. The bus allows each processor to have direct access to the memory of other processors, provides up to 120 million I / O operations per second, while having a low latency, less than 1 microsecond [5] .
There is also a modification of the platform XC30-AC. Positioned as a cheaper and more affordable version of the base system. Contains up to 128 processors per rack, scaling is limited to 8 racks. Peak performance per rack - 33 TFLOPS. Air cooling. [6]
In addition to CPUs, the platform allows the use of Intel Xeon Phi co- processors and Nvidia Tesla graphics accelerators for computations [7]
XC30 supercomputers are running the Cray Linux Environment , which includes the SUSE Linux Enterprise Server OS.
Use
The platform has become widespread in the world. In particular, it is used in the Research Center of the State Association of Scientific and Applied Research of Australia, the Scientific Supercomputer Center (CSC) of the Ministry of Education, Science and Culture of Finland, the Research Computing Center of the US Department of Energy in Berkeley , the Academic Computing Center (ACCMS) of Kyoto University in Japan , Supercomputing center of the University of Stuttgart (HLRS) in Germany [1] [8] , the medical complex Kong Sanatorium & Hong Hospital (HKSH) [9] in China, University of advanced science and tehn gies (JAIST) [10] in Japan, the German National Meteorological Service (DWD) [11] , the National Astronomical Observatory of Japan (NAOJ) [12] , Institute of Zuse and the University of Hannover named Gottfried Wilhelm Leibniz , members of the North German Supercomputing Alliance (HLRN) [13] .
