UGAS JUN21 TOKEN EXPIRING 30 JUN 2021 EXCHANGE

The latest supercomputer at NCMRWF,Noida "MIHIR" is a Cray-XC40 LC [Liquid Cooled] System with 2320 nodes running Intel Xeon Broadwell E5-2695 processors with a peak performance of 2,806 TFLOPS and a total system memory of 290TB. The system is composed of 13 Compute cabinets and uses Cray's Aries NOC with Dragonfly Interconnect network topology. In addition, the system consists of 12 Intel KNL 7210 accelerator nodes with a peak performance of 31.92 TFLOPS and a total memory of 1.1TB.

Each of the compute node has dual socket and runs Intel Xeon Broadwell E5-2695 v4 18-core processors with a clock speed of 2.1GHz . The entire system operates on Cray's customized Linux OS, called Cray Linux Environment. The cluster supports architecture specific compilers from Cray as well as Intel and open-source GNU compilers. System also hosts architecture specific parallel libraries like OPENMP, MPI, libsci, Intel Cluster software etc. Applications like GFS,WRF,UM N1024,CFS are available on the system for weather forecasting. To facilitate users with parallel program development, DDT parallel debugger and profiler is enabled on the system. The system uses PBS Pro as Workload Manager.
