IOT: Pratyush and Mihir - What is Pratush super computer?
From the official of Indian Institute of tropical meteorology website introduction, we have:
Pratyush is India’s fastest supercomputer yet (Jan 2018) with 4+ Petaflops of peak performance powered by Intel Xeon Broadwell E5-2695 v4 CPU and has total storage of 27 Petabytes. It has Intel KNL 7210 nodes with a peak performance of 42+ TFLOPS .
From Wikipedia, the free encyclopedia, we have:
Pratyush and Mihir are the supercomputers established at Indian Institute of Tropical Meteorology (IITM), Pune and National Center 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: ????????) 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. Both units and provides 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.
