India’s first multi-petaflop supercomputer, to improve monsoon and air quality forecast

India may get a better forecast of rainfall from the next monsoon season, while the number of farmers who receive weather information from IMD may increase by about 80% in next two years thanks to Pratyush, India’s first multi-petaflops supercomputer set up at a cost of Rs 450 crore.

Union Minister of Earth Sciences Dr. Harsh Vardhan dedicated India’s fastest and first multi-petaflops supercomputer to the nation on Monday at Pune-based Indian Institute of Tropical Meteorology (IITM). The supercomputer named as ‘Pratyush’ meaning the Sun, will be a national facility for improving weather and climate forecasts and services under the umbrella of the Ministry of Earth Sciences (MoES), Govt. of India.

MoES has been trying to scale down the weather forecast, which is presently given at district level, to block level. “With the help of Pratyush, blolck level forecast will be possible in another one year. The forecast of next monsoon will also get better. With the augmentation of this new ‘Pratyush” high performance computing (HPC) facility of 6.8 Peta Flops (PF), India’s ranking will move from the 368 th position to around the top 30 in the Top500 list of HPC facilities in the world.
