XC40 cabinet (front) with 48blades in groups of 16, each blade containing 4 nodes
TheCray XC40 is amassively parallelmultiprocessorsupercomputer manufactured byCray. It consists ofIntelHaswellXeonprocessors, with optionalNvidiaTesla or IntelXeon Phi accelerators, connected together by Cray's proprietary "Aries" interconnect, stored in air-cooled or liquid-cooled cabinets.[1] The XC series supercomputers are available with the Cray DataWarp applications I/O accelerator technology.[2]
ThePawsey Supercomputing Centre has a 35,712-core XC40 called "Magnus" for general science research. This supercomputer has a processing power of 1.097 petaflops.[3]
TheBureau 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.[4]
Supercomputer Education and Research Centre (SERC) at theIndian 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.[7]
Pratyush and Mihir are the supercomputers established atIndian Institute of Tropical Meteorology (IITM),[8] Pune andNational 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.
TheUK Met Office has three XC40s, with a total of 460,000cores, capable of 14petaflops peak.[14] It is currently the fastest machine in the world dedicated to weather and climate modeling,[15] and was the 11th fastest (but is no longer) on theTOP500 list when it was installed.[16]
