India’s fastest supercomputers in worlds TOP500 list of ISC
A computer that performs at or near the currently highest operational rate for machines is known as a supercomputer. It is exceptional in terms of performance, it handles very large databases or does a great amount of computation (or both). It also consists of multi-core processors and GPGPUs (general-purpose graphics processing units) which have enabled powerful machines for personal use. You must have heard about the list of supercomputers that comes out every year. This year rankings were announced on June 22 at the ongoing virtual event ISC (International Supercomputing Conference) High Performance 2020 Digital where two India’s fastest supercomputers, Praryush and Mihir was again featured in this TOP500 list where they secured 67th and 120th position respectively. The TOP500 list is a project that regularly ranks and evaluates the top 500 fastest supercomputer systems in the world.
However, the rankings of these supercomputers have fallen down as compared to the last year. According to the 2019 rankings report, Pratyush supercomputer was at 57th spot whereas Mihir’s ranking was at 100th.
Pratyush holds the first position in terms of the India’s fastest supercomputer with 3.7 petaflops high performance. For freshers, a petaflop is the measure of a computer’s processing speed. A petaflop is equal to a quadrillion or a thousand trillion calculations per second. This supercomputer is at the Indian Institute of Meteorology, Pune.
On the other hand, Mihir, which was ranked 120th in the TOP500 list of ISC has a capacity of 2.5 petaflops. This particularly fast machine is at the National Centre for Medium Range Weather Forecast in Noida.
These two India’s fastest supercomputers were installed in 2018 by the ministry of earth sciences. The estimated cost price of installing and setting them up was around Rs 440 crores, according to a report by The Economic Times.
These supercomputers are not only used for weather forecasts like monsoon but also informs cyclone, earthquakes and other extreme events. They can also help forecast air quality, flood, drought among other things.
