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.

Solidworks and other industry-class CAD software on linux (lemmy.world)

I am about to go to college for engineering and they require a Windows laptop because of the software we will be using (mostly solidworks I'm pretty sure) doesn't work on other operating systems. I primarily use windows day-to-day for gaming and such anyways so it's not a problem for me but I'm wondering if anyone had experience using solidworks or any other industry-class CAD software like Inventor on linux

Complex CAD is extremely demanding on CPU hardware. The tree is built sequentially and the math is all single threaded. Once CAD gets past a certain threshold the software needs to start tuning the way the Kernel works. The regular settings optimised for throughput and latency become a problem and the software needs away to change this. I've been messing with the Linux CPU scheduler to try to improve performance for FreeCAD designing complex assemblies on an older machine. I finally gave in and ordered another machine, but am still curious about CPU schedulers in general. I don't know how other software accomplishes improved performance on the hardware. I can only speculate, but I am willing to bet there are methods used to alter kernel parameters like the CPU scheduler in programs like Solidworks. The way these things are done is probably not portable to any other kernel.
