Linux Runs On 97.2 Percent Of Top 500 Supercomputers

Linux rules the world of supercomputers

Top500 has released its 45th annual report on world’s fastest supercomputers is out and once again Linux is ruling the world of supercomputers. This should not come as surprise because Linux has been ruling supercomputer world for several years now. Even in 2014, Linux was running on 485 out of top 500 supercomputers. There has been an increase in Linux share this year as 486 of top 500 super computers now run on Linux.

In other OSes, Unix runs on 12 supercomputer while Windows runs on only one supercomputer. The one remaining supercomputer runs ‘mixed’ OS (is it like dual boot?).

Top 100 supercomputers are running Linux

Digging deeper in the statistics gives you amusing information. China’s Tianhe 2, which runs Ubuntu, is the world’s fastest supercomputer with 33,862 teraflops per second, almost double of the second ranked Titan supercomputer by USA. USA has five while China, Japan, Germany, Switzerland and Saudi Arabia has one each in top ten fastest supercomputers. Here is a quick glance of top 10 supercomputers:

Even more interestingly, Linux runs on all top 100 supercomputers. Unix debuts at 107th ranked Russian supercomputer Polytechnic RSC Tornado. The only Windows running supercomputer is 436th ranked Magic Cube of China.

Like I said last year, “as Linux continues to dominate supercomputers, I hope enough attention is paid to desktop Linux world as well where Linux family lags even Windows Vista in terms of user share”.
