Cray supercomputer at Indian Institute of Tropical Meteorology ranks 39th in global Top500 ranking

Bangalore, June 29, 2018: Pratyush, the Cray XC40 supercomputer installed earlier this  year at the Indian Institute of Tropical Meteorology, Pune,  is India's  most powerful computing platform and ranks  39 in the global Top500 ranking published 2 days ago. 
At 3.7639 petaflops, it out performs  and pushes to  4th place  ( rank  327 of Top 500) , the 0.9 petaflop Cray XC40 at the  Supercomputing Education and Research Centre (SERC) of the Indian Institute of Science, Bangalore, which was hitherto, India's fastest high performance computer.
In fact the no. 2 supercomputer in India is also  at a meteorological facility -- the National Centre for Medium Range Weather Forecasting  in the national capital region:   another Cray XCS40 clocking 2.5704 petaflops ( Top500 rank 66).   India's department of Science and Technology  has turned out to be Cray's best customer in 2017, with these two buys.
The no. 3 supercomputer  based in India is a 1.123 teraflop  Lenovo C1040 machine working for the Chinese company's India software centre (Top 500 rank:  206).
A second and older machine at IITM is the 5th fastest India-based platform -- an iDataPlex DX360M clocking 0.7192 petaflops, just scraping into the top500 rankings at 496.
Since the National Supercomputing Mission was reignited in 2016 ( our story), it would appear the kitty of approximately Rs  45 billion (Rs 4500 crores)  is being used to buy rather than build -- the 2 Crays at IITM and NCMRWF must account for a large chunk of change.-
