Interesting how the tiny BSD fraction had a lead over Linux in 1995

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Surprised to learn that there were windows based Supercomputers.
Those were the basic entry level configurations needed to run Windows Vista with Aero effects.

I saw the thumbnail and thought this was a map of The Netherlands
"Is your UNIX Linux compatible?"
Now the real question is what package manager are they using? apt or yum? Lol

Maybe windows is not used in supercomputers often because unix and linux is more flexiable for the cpus they use(Power9,Sparc,etc)
Plus Linux doesn't limit you in the number of drives, whereas Windows limits you from A to Z. I read it here.
You can mount drives against folders in windows. So while D: is one drive, D:\Logs or D:\Cake can each be a different disk.

That's certainly a big part of it. When one needs to buy a metric crap load of CPUs, one tends to shop outside the popular defaults.
Another big reason, historically, is that Supercomputers didn't typically have any kind of non-command-line way to interact with them, and Windows needed it.
Until PowerShell and Windows 8, there were still substantial configuration options in Windows that were 100% managed by graphical packages. They could be changed by direct file edits and registry editing, but it added a lot of risk. All of the "did I make a mistake" tools were graphical and so unavailable from command line.
So any version of Windows stripped down enough to run on any super-computer cluster was going to be missing a lot of features, until around 2006.
Since Linux and Unix started as command line operating systems, both already had plenty fully featured options for Supercomputing.
More importantly, they can't adapt Windows to their needs.
Yep the other reason.
I’m confused on why they separate BSD from Unix. BSD is a Unix variant.
Unix is basically a brand name.
BSD had to be completely re-written to remove all Unix code, so it could be published under a free license.
It isn't Unix certified.
So it is Unix-derived, but not currently a Unix system (which is a completely meaningless term anyway).
But OS X, macOS, and at least one Linux distro are/were UNIX certified.
Yup. It is all about paying the price, Microsoft could technically get Windows certified as UNIX. IBM did just that with its mainframe OS. Here's a list of certified UNIX systems: https://www.opengroup.org/openbrand/register/
