India has 9 of the world's 500 fastest supercomputers; China has 168

India's supercomputing story continues to be on the wane. For the first time since 2007, an Indian supercomputer does not feature among the world's fastest 100

India has a billion people. And Indian government is going for massive digitalization, with its Digital India program. That should create a high demand for a lot of high performance computing infrastructure. Yet, according to June 2016 data released by, that tracks and releases biannual lists of world’s fastest supercomputers, India has just nine of the 500 fastest supercomputing sites in the world. In November 2015, India had 11 such supercomputing sites.



India, often dubbed IT superpower by media  and analysts, also has no major single achievement to show. The fastest Indian supercomputer is not even among top 100 in the world. It is for the first time in the last nine years that an Indian supercomputer does not find a place among the fastest 100. The fastest one is in Supercomputer Education and Research Centre (SERC) at Indian Institute of Science that occupies the 110th position. The Cray supercomputer was the 94th fastest in the last list, released in November 2015.  In November 2007, an Indian supercomputer (Tata Sons’ EKA) was the fourth fastest in the world, according to the same list. Since then, it has been a constant slide.



In terms of speed, that time the world’s fastest supercomputer was four times faster than India’s fastest. Today, the ratio is more than 100.

The Top 500 list this time has another major shift. For the first time, China has overtaken the US as the country with the maximum fastest supercomputers. China has 168 in the list. The two countries, China and US together, account for two-third of the world’s top 500 supercomputers.



It may be noted here that former IT minister Kapil Sibal had announced his government’s plans to build the fastest supercomputer in the world and had claimed he even had created a plan for it. 


Hewlett-Packard has most of the world's fastest supercomputing sites.
