There has been a change to the reports of the top 500 supercomputer list. They now indicate which OSes are run on the systems in the top 500. A ***whopping*** 78.2% (or 391) of all the top 500 supercomputers run a linux flavor or Linux compined with something else. Not sure what that is an indication of. A mixed Linux + ? OS? What's up with that? Oh yeah, 4 BSDs and 5 Macs. One of those MACs is *homegrown* and made the top 15, homegrown being made by the company, which looks like it may do some hush-hush work for the DOD.
