On linux you can find the size of L2 cache from the os command line: lscpu | grep L2 On windows you can find the size of L2 cache from task manager (at least under windows 11 -- it's down on the lower right of the performance tab, and the performance tab is selected on the left side of task manager -- it's an approximately square icon containing a squiggle (representing an oscilloscope trace, I think)). I don't know how to find this on OSX. If there's a way of checking cache sizes in C, it might be nice to have a 9!: foreign or a T. query to report this kind of architectural information.
