Hi Nick, For teaching you may be able to get some inspiration from my class assignments. Specifically, assignment 5 is about coherence: https://jlpteaching.github.io/comparch/modules/gem5/assignment5/
All of the code for my assignments can be found here under different branches for each assignment: https://github.com/jlpteaching/gem5-assignment-template Cheers, Jason On Fri, Jun 9, 2023 at 9:08 AM Beser, Nicholas D. via gem5-users < gem5-users@gem5.org> wrote: > I will take a look at docker.
