Supercomputing with Penguins

I hadn't realized that most of the world's supercomputers were running Linux (as of June 2009). When did that happen? Apparently between late 2003 and early 2004 Linux began to displace the Unix memes from their virtual niche in the supercomputing ecosphere. I don't know the history, but the shift is so fast it suggests that Linux became more efficient and was adopted en masse by supercomputer admins. Or I suppose it could be a licensing thing. Anyway, Linux was adopted because it was better for one reason or another.

Victory over all in the supercomputing field doesn't necessarily mean Linux is headed for supremacy on the desktop, but it's still a good sign. By the way, Top500.org has some interesting charts, historical graphs, and tables you can generate.
