Pratyush: India's Most Powerful Supercomputer

Pratyush is the first Petaflop Supercomputer developed by India. Pratyush an array of computers that can deliver a peak power of 6.8 petaflops. Pratyush is the fourth fastest supercomputer in the world dedicated for weather and climate research, and follows machines in Japan, USA and the United Kingdom. It will also move an Indian supercomputer from the 300s to the 30s in the Top500 list, a respected international tracker of the world’s fastest supercomputers.

Pratyush is expected to add significantly to the nation’s capacity in weather forecasting and climate monitoring and takes India to the fourth position – only behind the UK, Japan, and the USA in terms of dedicated high powered computing resources for weather and climate monitoring. Pratyush, which is essentially an array of computers, draws 4 Petaflops of it’s peak power from IITM, Pune, and the remaining 2.8 Petaflops come from the National Centre for Medium-Range Weather Forecast (NCMRWF) at Noida.
