DMPQ: What is ‘Pratyush’? Discuss its advantage. (Science)

 Pratyush is an array of computers that will be used for weather and climate research. Pratyush is the fourth fastest supercomputer in the world dedicated to weather and climate research and follows machines in Japan, USA and the United Kingdom. Pratyush 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.

A key function of the machine’s computing power would be monsoon forecasting using a dynamical model This requires simulating the weather for a given month — say March — and letting a custom-built model calculate how the actual weather will play out over June, July, August and SeptemberWith the new system, it would be possible to map regions in India at a resolution of 3 km and the globe at 12 km.
