When it comes to groundbreaking innovations in supercomputing over the last decade, there are few shifts that made bigger waves than the introduction of heterogeneous computing. Coupling high-performance host processors with a graphic-processing boost has helped several top-ranked supercomputers achieve performance and energy …
And they all run Windows 10?....How About OS X?... Nope, none of them run anything from Microsoft or Apple:-
1. Titan Supercomputer at Oak Ridge National Lab:-
Cray Linux Environment
2. “Piz Daint” at the Swiss National Supercomputing Centre:-
Cray Linux Environment
3. Tulip Trading Supercomputer in Australia:-
Centos 6 (Linux)
4. Eni S.p.A Oil and Gas Supercomputer in Italy
5. “TSUBAME 2.5” at the Tokyo Institute of Technology
SUSE Linux Enterprise Server 11
6. Tianhe-1A at the National Supercomputing Center in Tianjin, China
7. Lomonosov 2 at Moscow State University Research Computing Center in Russia
8. Nebulae at the National Supercomputing Centre in Shenzhen
9. XStream at the Stanford Research Computing Center
Out of the 500, 488 are now Linux, that's 97%. At number 436 there is this one and only Windows machine, in China. Then there are 10 Unix left the first as number 107 in Russia. The one missing is registered as mixed, number 411 in Saudi Arabia, apparently a Power machine by IBM, Aix plus Linux perhaps.
It is of course also possible to run Windows beneath Linux, although I have no figures on that usage.
The part of Linux is not surprising at all, Linux started to appear on the list more than 15 years ago and is now the standard. Was it not Linux it would be Unix versions.
While I am a Linux user and fan, if you want, I want to point out that we should not forget guys like Ken Thompson and Dennis Ritchie who designed Unix and got so many things right almost 50 years ago. Dennis Ritchie died in 2011.
As for the data it's on http://top500.org/statistics/sublist/
The slowing performance gains of CPUs in recent years has reduced the need to refresh desktops/laptop as often, and it's looking the same for mobile computing devices with tablet sales now falling. Are GPU performance gains also slowing, and has this affected the refresh rate of HPC systems?
