Our group built an operating system from scratch conforming to Nachos guidelines. Our implementation includes threads, multiprogramming, and distributed key-value stores. For a description of the project, please see class website. I'm not uploading any project design documents or code from our group since this project is used every year and we were instructed to not make our files available online to prevent cheating by future students. If you're not a student though, feel free to contact me for code/docs.
