'From ZDNet: "The latest TOP500 Supercomputer list is out. What's not surprising is that Linux runs on every last one of the world's fastest supercomputers. Linux has dominated supercomputing for years. But, Linux only took over supercomputing lock, stock, and barrel in November 2017. That was the first time all of the TOP500 machines were running Linux. Before that IBM AIX, a Unix variant, was hanging on for dear life low on the list." An interesting architectural note: "GPUs, not CPUs, now power most of supercomputers' speed."' -- source: https://linux.slashdot.org/story/18/06/27/152216 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/
