Summary: When it comes to the world’s top computers, GNU/Linux is virtually without any competition
It is GNU/Linux occupying 10 out of 10 (top 10) ‘super’ servers. The numbers are out and they show this, based on Green500  and TOP500 [2,3], which has GNU/Linux everywhere but 18 computers in the top 500. If this isn’t a sign of GNU/Linux having clear technical superiority, what is? Decisions regarding expensive computers such as these are not made based on some sole Microsoft MVP or a clueless manager (I have seen this personally) who has a pact with Microsoft. █

The November 2013 edition of the Green500 List has be released, just two days after the TOP500 List.
Unlike the TOP500 List, which lists 500 of the worlds fastest supercomputers, the Green500 List lists the most energy-efficient supercomputers that made the TOP500 List. So for the Green500, it’s not about how fast, but how energy-efficient. That’s why China’s Tianhe-2, which topped the November 2013 TOP500 List, did not even make the top 10 of the Green500 List for the same month. Rather, it ranked number 41.
“Once the definition and code for the HPCG is in a stable condition we envision collecting results for it in parallel to the ongoing effort for the HPL benchmark,” said Erich Strohmaier, head of the Future Technologies Group at Lawrence Berkeley National Laboratories and Top500.org editor. “For the foreseeable future the TOP500 will be based on the HPL benchmark test but we would hope to provide additional value and information by collecting and publishing numbers for new benchmark such as HPCG as well.”
Supercomputing 13, which takes place in Denver this week, began with the announcement of the latest Top500 list of the world’s fastest computers and Nvidia’s release of the Tesla K40 accelerator.
The November 2013 edition of the list of the world’s fastest supercomputers has just been released. Known as the TOP500 List, it is released twice a year, first in June, then in November.
The TOP500 List began in June 1993, ran again in November of that year and has been repeated in that order since. The November 2013 edition is the 42nd.
This latest edition is not that much different from the previous edition, which was also topped by the Tianhe-2 supercomputer, which is built and maintained by China’s National University of Defense Technology. It retained its top spot “with a performance of 33.86 petaflop/s (quadrillions of calculations per second).” Folks, that’s fast, and impressive.
