But that was sometime back in 2012-2013 timeframe.

After that I think Microsoft gave up trying to get on the list, nobody could afford to use Windows.

Looking at https://technet.microsoft.com/en-us/...(v=ws.11).aspx, it is only a package for Windows Server 2012, and that would have gone out of support next year, but appears to have been extended a couple of years.

I saw the owner of the Top500.org speak at an event a year or two ago, and he said there are several large super computers running Linux that are just too busy to run the benchmarks in order to get listed on the Top500, so the numbers might look different if they could go offline long enough to benchmark.

Not that the numbers need to look different; they're quite nice. I just thought it was interesting that some Linux farms out there are too busy working to brag.

Yeah. Usually only new installations, or major expansions of a supercomputer have the available time - due to it being part of the acceptance tests, so adding a submission isn't that much more work (and it raises a LOT of PR value). One center I worked at only submitted the major Cray/IBM systems - but didn't bother with the expanded mid line ones used for development (it had 512 processors, but only the 1048 processor Cray unit was submitted as it was undergoing acceptance tests).

And they no longer even show up.
