Fast, Faster, Fastest: Linux rules supercomputing

A few decades back I was working at Goddard Space Flight Center. I’m sorry to say that I left just before some people I’d met, Don Becker and Thomas Sterling, built the first Linux cluster, Beowulf. They didn’t know it, but by making a cheap cluster from 16 486DXs processors and 10Mbps Ethernet, they were creating the ancestor to today’s Linux supercomputers. Now, not 20 years later, well over 90% of the world top 500 supercomputers are running Linux.
