Q.The terms Mihir, Param Siddhi and Pratyush are sometimes seen in news are actually:

a)Indigenous Submarines




Param Siddhi

  • It is a high-performance computing-artificial intelligence (HPC-AI) supercomputer established under National Supercomputing Mission (NSM) at C-DAC.
  • It was commissioned by the C-DAC earlier and has been developed in association with chipmaker Nvidia and French IT consulting firm Atos.
  • It will help deep learning, visual computing, virtual reality, accelerated computing, as well as graphics virtualization.
  • The computer is expected to be used as a platform for academia, scientific research, startups and more.

Other Indian supercomputers

  • PARAM-Siddhi is the second Indian supercomputer to be entered in the top 100 on the Top500 list.
  • Pratyush, a supercomputer used for weather forecasting at the Indian Institute of Tropical Meteorology, ranked 78th on the November edition of the list.
  • It was ranked 66th in the June rankings announced by the project.
  • Another Indian supercomputer, Mihir (146th on the list), clubs with Pratyush to generate enough computing power to match PARAM-Siddhi.

Who topped the rankings?

  • The Top500 project tracks the most powerful supercomputers in the world and is published twice a year.
  • Japanese supercomputer Fugaku (442 petaflops) and IBM’s Summit (148.8 petaflops) are the two most powerful supercomputers in the world, according to the list.
  • Chinese Sunway TaihuLight is number four on the list (93 petaflops), developed by the National Research Center of Parallel Computer Engineering & Technology (NRCPC) in China.


National Supercomputing Mission (NSM)


  • A petaflop is a measure of a computer’s processing speed and can be expressed as A thousand trillion floating-point operations per second (FLOPS) A thousand teraflops.
  • In computing, floating-point operations per second is a measure of computer performance, useful in fields of scientific computations that require floating-point calculations.
  • For such cases, it is a more accurate measure than measuring instructions per second.
