In the latest Top500 supercomputer rankings, 476 of the top 500 fastest supercomputers, 95.2 percent, in the world run Linux. Linux has ruled supercomputing for years. But, it wasn't always that way.
When the first Top500 supercomputer list was compiled in June 1993, Linux was just gathering steam. Indeed, in 1993, the first successful Linux distributions, Slackware and Debian were only just getting off the ground.
What happened next, as reported in The Linux Foundation's forthcoming report, 20 years of Top500.org Supercomputer Data Links Linux With Advances in Computing Performance, was that "after first appearing on the list in 1998, Linux has consistently dominated the top 10 over the past decade and has comprised more than 90 percent of the list since June 2010."
