India's Ranking Among Top500 Supercomputer Powers Slips

CHINA MAINTAINS LEAD WITH TOP TWO SYSTEMS

NECK AND NECK WITH US ON NUMBER OF SYSTEMS IN LIST 

India’s ranking in the Top 500 supercomputer list, has slipped further even as the country ramps up its efforts to emerge a leading player in the space with its National Supercomputer Mission (NSM), as part of which it wants to set up a grid of 75 plus supercomputers in the country at a cost Rs 4500 crore over the next five years.

The list is compiled once every six months by Erich Strohmaier and Horst Simon of Lawrence Berkeley National Laboratory; Jack Dongarra of the University of Tennessee, Knoxville; and Martin Meuer of ISC Group, Germany, and considered the only authoritative ranking of computing power across the world.

From nine systems in the list of the world’s Top 500 supercomputers, only five from India were able to make it to the latest list put out by the combine while the ranking dropped from 110 to 139. Poland replaced India at the 110th spot.

However, the CRAY XC40 located at the Supercomputer Education and Research Centre (SERC) at the Indian Institute of Science, Bangalore has maintained its position as the most powerful machine in India as per the Top500 list.

China has maintained its top 1 and 2 ranking going neck and neck with the US in the number of systems that made it to the list 171 systems apiece. 

After US and China, Germany claims the most systems with 31, followed by Japan with 27, France with 20, and the UK with 13. A year ago the US was the clear leader with 200 systems, while China had 108, Japan had 37, Germany had 33, and both France and the UK had 18.

In addition to matching each other in system count in the latest rankings, China and the US are running neck and neck in aggregate Linpack performance. The US holds the narrowest of leads, with 33.9 percent of the total; China is second with 33.3 percent. The total performance of all 500 computers on the list is now 672 petaflops, a 60 percent increase from a year ago.
