Cray XC40
Cray XC40 is a supercomputer system from the manufacturer Cray Research . It was presented in 2014 and is the next generation of the XC30 systems. A first system was sold for research on nuclear weapons . The XC40 is based on the Intel Xeon processor of the E5-2600v3 series and is available with liquid cooling or air cooling.
In mid-2016, Crays XC40 placed three of the ten most powerful supercomputer systems in the world in the TOP500 list.
One system, Cray XC40 "Hazel Hen" is located at the German high-performance computing center Stuttgart (HLRS). Expansion stage by February 2020: 41 computer cabinets, 7712 nodes with 128 GB RAM / Intel Xeon E5-2680. Total weight 61.5 t, power consumption 3.2 megawatts. The computer performance was 5.6 PetaFLOPS ( peak 7.42 PetaFLOPS). The successor system Hawk was inaugurated in February 2020, it now consists of 44 computer cabinets with 5632 nodes and a power consumption of up to 4.1 megawatts. The computer performance was increased to 24 PetaFLOPS ( peak 26 PetaFLOPS).
The predecessor model Cray XC30 was presented in 2012. It is used by the German Weather Service and the European Center for Medium-Range Weather Forecasts , among others .
The successor model Cray XC50 was presented at the end of 2016. It works with Nvidia Tesla P100 and should achieve 1 PetaFLOP (peak) per computer cabinet.
Specifications
A computer cabinet consists of three chassis, each of which accommodates 16 blades . The blades in turn are equipped with two processor daughter cards . The blades also each have an Aries chip for the interconnect and PCIe slots for SSDs , Nvidia Tesla K40 and Xeon Phi. A processor daughter card can accommodate four Xeon CPUs with four DDR4 memory modules each . The maximum configuration is 384 CPUs per cabinet.
