'''Pratyush''' '''and Mihir''' are the [[supercomputer]]s established at [[Indian Institute of Tropical Meteorology]] (IITM), [[Pune]] and [[National Centre for Medium Range Weather Forecasting|National Centre for Medium Range Weather Forecast]] (NCMRWF), [[Noida]] respectively. As of January 2018, Pratyush and Mihir are the fastest supercomputer in India with a maximum speed of 6.8 [[FLOPS|PetaFlops]] at a total cost of [[Indian rupee|INR]] 438.9 Crore.<ref name=":0">{{Cite web|url=http://pib.nic.in/newsite/PrintRelease.aspx?relid=178346|title=High Performance Computing (HPC) Systems Pratyush and Mihir|website=pib.nic.in|access-date=2018-06-27}}</ref> The system was inaugurated by [[Harsh Vardhan (Delhi politician)|Dr. Harsh Vardhan]], [[Minister of Science and Technology (India)|Union Minister for science and technology]], on 8 January 2018.The word 'Pratyush' ({{lang-hi|प्रत्युष}}) defines the rising sun.<ref name=":0" /><ref name="hd">{{cite web|url=http://www.thehindu.com/news/national/india-unveils-pratyush-its-fastest-supercomputer-yet/article22398732.ece|title=India unveils Pratyush, its fastest supercomputer yet|date=2018-01-08|publisher=[[The Hindu]]|archiveurl=https://web.archive.org/web/20180126080608/http://www.thehindu.com/news/national/india-unveils-pratyush-its-fastest-supercomputer-yet/article22398732.ece|archivedate=2018-01-26|accessdate=2018-01-26}}</ref><ref name="ine" /><ref name="fit" />

Being a [[High Performance Computing]] (HPC) facility, Pratyush and Mihir consists of several [[computer]]s that can deliver a peak power of 6.8 [[FLOPS|PetaFlops]].{{refn|group=note|[[FLOPS|PetaFlops]] is a measure of computing capacity of a system.

Pratyush and Mihir are two High Performance Computing (HPC) units. They are located at two government institutes, one being 4.0 PetaFlops unit at [[Indian Institute of Tropical Meteorology|IITM]], [[Pune]] and another 2.8 PetaFlops unit at the [[National Centre for Medium Range Weather Forecasting]] (NCMRWF), [[Noida]]. They provide a combined output of 6.8 PetaFlops.<ref name=fit/><ref name=":0" />

Pratyush and Mihir are used in the fields of [[weather forecasting]] and [[climate]] monitoring in India.<ref name=fit/> It helps the country to make better forecasts in terms of [[Monsoon]], [[fishing]], [[air quality]], extreme events like [[Tsunami]], [[cyclone]]s, [[earthquake]]s, [[lightning]] and other [[Natural Disaster|natural calamities]] such as [[flood]]s, [[drought]]s etc.<ref name=ine>{{cite web |url=http://indianexpress.com/article/technology/tech-news-technology/indias-fastest-supercomputer-established-at-punes-iitm-5017530/ |title=India’s fastest supercomputer ‘Pratyush’ established at Pune’s IITM |publisher=[[The Indian Express]] |date=2018-01-09 |accessdate=2018-01-26 |archiveurl=https://web.archive.org/web/20180126080849/http://indianexpress.com/article/technology/tech-news-technology/indias-fastest-supercomputer-established-at-punes-iitm-5017530/ |archivedate=2018-01-26}}</ref> [[India]] is the fourth country in the world to have a [[High Performance Computing]] facility dedicated for [[weather]] and [[climate]] research after [[Japan]], the [[United States]] and the [[United Kingdom]].<ref name=fit/><ref name=hd/>

{{Main|Supercomputing in India}}

The [[High Performance Computing]] (HPC) facility in [[India]] has grown from 40 [[FLOPS|TeraFlops]] in 2008 to 1 [[FLOPS|PetaFlops]] in the year 2013-14.<ref name=fit/> But India still remained at a lower position in terms of HPC infrastructure rankings in the world.<ref name=fit/>

[[Government of India]] approved 400 crore [[Indian Rupee|Rupees]] in 2017 to build a supercomputer with a computing capacity of 10 PetaFlops.<ref name=hd/> The engineers of [[Indian Institute of Tropical Meteorology|IITM, Pune]] worked under the leadership of Suryachandra A Rao and built Pratyush in 2018.<ref name=hit>{{cite web |url=https://m.hindustantimes.com/mumbai-news/supercomputer-pratyush-hpc-to-boost-india-s-rankings-forecast-weather-faster/story-DL1Cgzb1icM7oA8kf9gDWN.html |title=Supercomputer Pratyush HPC to boost India’s rankings, forecast weather faster |publisher=[[The Hindustan Times]] |date=2018-01-08 |accessdate=2018-01-26 |archiveurl=https://web.archive.org/web/20180126081633/https://m.hindustantimes.com/mumbai-news/supercomputer-pratyush-hpc-to-boost-india-s-rankings-forecast-weather-faster/story-DL1Cgzb1icM7oA8kf9gDWN.html |archivedate=2018-01-26}}</ref> The overall cost was around 450 crore [[Indian Rupee]]s.<ref name=fit/>

With the introduction of Pratyush and Mihir, India hopes to move from the 165th position to gain a position in the top 30s in the [[Top500|Top500 list of supercomputers]] in the world.<ref name=int>{{cite web |url=https://www.indiatoday.in/education-today/gk-current-affairs/story/fastest-supercomputer-india-pratyush-in-iitm-pune-1130486-2018-01-09 |title=India sets up its fastest supercomputer Pratyush at Pune's IITM |publisher=[[India Today]] |date=2018-01-09 |accessdate=2018-01-26 |archiveurl=https://web.archive.org/web/20180126081150/https://www.indiatoday.in/education-today/gk-current-affairs/story/fastest-supercomputer-india-pratyush-in-iitm-pune-1130486-2018-01-09 |archivedate=2018-01-26}}</ref>
