Pratyush, fastest supercomputer based in India
 
 
Indian presence in global Top 500 supercomputer list remains unchanged

November 14 2018:   India's presence in the global Top 500 fastest supercomputers   released on November 13, remains unchanged since the last rankings six months ago
The Indian  Institute of Tropical Meteorology's Cray XC 40- LC  named Pratyush, remains  the fastest high performance computer based in India, clocking  3.7639 peta flops, though it has slipped  6 places in the global rankings from   no. 39 to no. 45.
The second-fastest India-based platform  at no. 73 remains the  same  -- another Cray XC 40 at National Centre for Medium Range Weather Forecasting clocking  2.5704 peta flops.
Next  at no 338, comes a supercomputer from Lenovo the 1.123  peta flop C 1040, used by the company for its  research in India.
Bringing up the  rear  as far as supercomputers in India are concerned,  that make this half-year's Top 500, at no 486, is yet another  XC40,  the sub-peta flop (901 teraflop) system at the Supercomputer Education and Research Centre (SERC) of the Indian Institute of Science, Bangalore.
This only underlines  what seems to be the current thrust of India's supercomputing programme  whose mantra seems to be "Why make when we can buy?"
Indeed, the two fastest machines   at IITM and NCMRWF,  were acquired  after  India dusted and re-launched  its National Supercomputing Mission in 2015 with a Rs 45 billion ( Rs 4500 crore)  kitty with its current stated objective of initially buying  6 supercomputers and gradually assembling them in India. An indigenously developed supercomputer is now relegated to the third phase of the 7-year programme.  This has created  very good business for US supercomputer makers like Cray, who  made  some of their biggest sales last year, to India.
The current thrust of the government's supercomputing plans are a far cry from the 1980s, when  India entered the  club of high performance computer (HPC) developers  with the Param series of indigenous machines designed and developed by the Centre for Development of Advanced Computing ( C-DAC).  Iterations of Param figured in the Top 500 lists for  many years  -- but  in the last decade, the series has not kept pace with the global march to peta flop and  --soon  -- exaflop systems. 

Other government departments which had active supercomputing programmes  like  Atomic Energy (Anupam), DRDO ( ANURAG), CSIR/NAL (Flosolver)  and briefly C-DIT   are not known to have significantly  grown beyond their own  internal requirements.

This only reinforces  the  impression that India's national priorities in supercomputing are  today seeing a subtle shift from  build to buy.
