Cray XC40 explained
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 XC series supercomputers are available with the Cray DataWarp applications I/O accelerator technology.
Deployed systems
Australia
- The Pawsey Supercomputing Centre has a 35,712-core XC40 called "Magnus" for general science research. This supercomputer has a processing power of 1.097 petaflops.
- The Bureau of Meteorology has a 51,840-core XC40 called "Australis" with 276 TB of RAM and a usable storage of 4.3 PB. The supercomputer with a peak performance of 1.6 petaflops provides the operational computing capability for weather, climate, ocean and wave numerical prediction and simulation.
Finland
- National IT center for science CSC computer "Sisu" was completed as XC40 in 2014. It has 40,512 cores with overall peak performance of 1,688 TFlops.
Germany
India
- Supercomputer Education and Research Centre (SERC) at the Indian Institute of Science has an XC40 supercomputer named SahasraT, with 1,376 compute nodes (33,024 Intel Haswell Xeon cores), together with Intel Xeon Phi and NVIDIA K40 GPU accelerators.
- Pratyush and Mihir are the supercomputers established at Indian Institute of Tropical Meteorology (IITM), Pune and National Center for Medium Range Weather Forecast (NCMRWF) respectively. Pratyush and Mihir are two High Performance Computing (HPC) units. They are located at two government institutes, one being 4.0 PetaFlops unit at IITM, Pune and another 2.8 PetaFlops unit at the National Centre for Medium Range Weather Forecasting (NCMRWF), Noida. Both units and provides a combined output of 6.8 PetaFlops.
Japan
The Center for Computational Astrophysics at the National Astronomical Observatory of Japan have an XC40 system named "ATERUI". This is an upgrade from a previous Cray XC30 system.
Poland
Saudi Arabia
Sweden
Switzerland
United Kingdom
- The UK Met Office has three XC40s, with a total of 460,000 cores, capable of 14 petaflops peak.[1] It is currently the fastest machine in the world dedicated to weather and climate modeling,[2] and was the 11th fastest (but is no longer) on the TOP500 list when it was installed.[3]
