NetBSD because "Of course it runs NetBSD" :)

#4A win for open source. I was just thinking the other day that it's a shame that Linus is not a billionaire. Seems he's doing just fine however:
"Finnish-American software engineer and hacker Linus Torvalds has as estimated net worth of $150 million and an estimated annual salary of $10 million. He earned his net worth as the principal force behind the development of the Linux kernel."

IIRC at one point Microsoft paid one of them to run Windows and years ago there was one running OS X. Decades ago during the Unix Wars there used to be proprietary HPC OSes.

FreeBSD? Netflix runs it on their OpenConnect boxes, but that's about the extent of my knowledge.

A few years ago I remember some of them were running BSD derivatives.

Depends on what you want to do with it.
Basically anything else that operates on their hardware infrastructure is ok. Though it may be very challenging to get a useful supercomputer on very old operating systems.
I'm guessing one of the major factors to decide for Linux is this:
"The licensing cost of a custom, self-supported Linux distribution is the same, whether you're using 20 nodes or 20-million nodes."

The Cray I used to program used an OS called Unicos, which was a variant of Unix.

#10Note that BlueGene/Q is commonly reported to run "Linux" but 99% of the nodes are running CNK instead. https://computing.llnl.gov/tutorials/bgq/#Software
