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.

Nomenclature: CPU Core/Threads vs Kernel Threads - how do you avoid ambiguity? (lemmy.world)

Reading Robert Love's Linux Kernel Development. I'm just a hobbyist. I'm familiar with hardware manufacturers listing CPU cores that each have two threads.

Reading about Kernel processes and executing threads makes very little sense compared to a hardware core with two threads. One of my main goals is to understand the CPU scheduler, and really how it relates to cache management, pipeline, and branch prediction. I'm also curious about the difference in these systems when multi (hw) threading is turned off.

For me it's the opposite: a hardware core "having two threads" still sounds a bit strange. It can run two threads at the same time. Maybe Intel should have invented a better name for the thread-runner-thingie.
