Pratyush and Mihir

Pratyush and Mihir is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Pratyush and Mihir rather than just read about it. In short: Pratyush and Mihir are the supercomputers established at Indian Institute of Tropical Meteorology (IITM), Pune and 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 PetaFlops at a total cost of INR 438.9 Crore.

Key takeaways

Pratyush and Mihir belongs to computer science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Pratyush and Mihir to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Pratyush and Mihir from memory before moving on to harder problems.

Reference excerpt

Pratyush and Mihir are the supercomputers established at Indian Institute of Tropical Meteorology (IITM), Pune and 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 PetaFlops at a total cost of INR 438.9 Crore. The system was inaugurated by Dr. Harsh Vardhan, Union Minister for science and technology, on 8 January 2018.The word 'Pratyush' (Hindi: प्रत्युष) defines the rising sun. Being a High Performance Computing (HPC) facility, Pratyush and Mihir consists of several computers that can deliver a peak power of 6.8 PetaFlops. It is the first multi-PetaFlops supercomputer ever built in India. Pratyush and Mihir are two High Performance Computing (HPC) units. They are located at two government institutes, one being 4.0 PetaFlops unit at 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. Pratyush and Mihir are used in the fields of weather forecasting and climate monitoring in India. It helps the country to make better forecasts in terms of Monsoon, fishing, air quality, extreme events like Tsunami, cyclones, earthquakes, lightning and other natural calamities such as floods, droughts etc. 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.

History

The High Performance Computing (HPC) facility in India has grown from 40 TeraFlops in 2008 to 1 PetaFlops in the year 2013–14. But India still remained at a lower position in terms of HPC infrastructure rankings in the world. Government of India approved 400 crore Rupees in 2017 to build a supercomputer with a computing capacity of 10 PetaFlops. The engineers of IITM, Pune worked under the leadership of Suryachandra A Rao and built Pratyush in 2018. The overall cost was around 450 crore Indian Rupees. 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 list of supercomputers in the world.

Worked examples

Example 1 — a first encounter with Pratyush and Mihir

Start with the simplest possible case. Write down what Pratyush and Mihir claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Pratyush and Mihir before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Pratyush and Mihir ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Pratyush and Mihir

In research: Pratyush and Mihir appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Pratyush and Mihir in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Pratyush and Mihir is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2018 establishments in Maharashtra, Computer-related introductions in 2018, Computers designed in India, so understanding it makes those chapters shorter.
In everyday life: Look for Pratyush and Mihir outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
