June 1 2022: The three India- based super computers in the global ranking of the world's fastest supercomputers ranking remained unchanged since this time last year. What has changed is their position in the ranking which has slipped a few places.
According to the semi-annual Top500 ranking of supercomputers released today:
-The fastest platform in India at # 111, is the Param Sidhi AI – an NVIDIA DGX-A100 acquired from Atos, housed in the Centre for Development of Advanced Computing (C-DAC) Pune and clocking 4.62 Petaaflops.( One Peta or Pflop =1000 tera or TFlop)
-At # 132 is Pratyush, a Cray XC40 from Cray/HPE and used by the Indian Institute of Tropical Meteorology, also in Pune. It clocks 3.76 PFlops.
-At rank # 249 is Mihir, another Cray XC40 from Cray/HPE housed in Delhi at the National Centre for Medium Range Weather Forecasting. Its max speed is 2.57 PFlops.
Meanwhile, on the global plane, a significant threshold has been broken: a US machine at Oak Ridge National Laboratory is the first computer in the world to breach the exascale barrier, clocking 1.102 exaflops. One exa flop means one quintillion flops ( 10 raised to the power 18) -- that is 1000 peta flops.
