PRATYUSH - Indias Fastest Supercomputer

India is proving itself in every field possible and technology is no less here. On Monday, India unveiled its fastest supercomputer 'Pratyush' which is an array of computers that can deliver a peak power of 6.8 petaflops. One petaflop is a million billion floating point operations per second and is a reflection of the computing capacity of a system.

According to reports of Indian Institute of Tropical Meteorology (IITM), Pratyush is the fourth fastest supercomputer in the world which is designed for weather and climate research. It will also upgrade an Indian supercomputer from the 300s to the 30s in the Top500 list, a respected international tracker of the world’s fastest supercomputers.

The government had sanctioned last year ₹400 crore in order to put in place a 10-petaflop machine. The main functionality of this supercomputer would be monsoon forecasting with the help of a dynamic model.This requires simulating the weather for a given month and letting a custom-built model calculate how the actual weather will play out over June, July, August and September. This new system would provide wings to the technology and it would be possible to map regions in India at a resolution of 3 km and the globe at 12 km.

The machines will be installed at two government institutes: 4.0 petaflops HPC facility at IITM, Pune; and 2.8 petaflops facility at the National Centre for Medium Range Weather Forecast, Noida.
