What are Supercomputers?

  • A supercomputeris a computer with a high level of performance as compared to a general-purpose computer. The performance of a supercomputer is commonly measured in floating-point operations per second (FLOPS) instead of million instructions per second (MIPS).

Some of the supercomputers of India


  • PARAM Siddhi-AI has aRpeak capacity of 5.267 Petaflops and Rmax capacity of 4.6 Petaflops.
  • It was led and built on NVIDIA DGX SuperPOD architecture.
  • The system is jointly built by the Department of Science and Technology and the Ministry of Electronics and IT.


  • ‘Mihir’ is a 2.8 Petaflop supercomputer.
  • It is one of the powerful systems owned by the Ministry of Earth Sciences and has helped improve India’s forecasting skills.


  • It is the first multi-PetaFlopssupercomputer ever built in India with 4 Petaflopcapacity.

National Supercomputing Mission

  • The mission was launched in 2015.
  • It was launched by the Ministry of Electronics and Information Technology.
  • It aims to install 73 indigenous supercomputers throughout the country by 2022.
  • This is a seven-year program.
