CPSC 331 Operating Systems Spring 2026

CPSC 331 Schedule

Readings are listed on the schedule page on the day when they will be discussed in class. "OSTEP" refers to the textbook (Operating Systems: Three Easy Pieces). Readings are the first introduction for most material — it often takes more than one encounter to fully absorb something, and class time is more effective if it can be used to fill in the gaps and answer questions about things you have already started to think about. You are encouraged to complete the assigned reading before class to identify the main ideas and note questions, and then revisit the reading after class to more fully understand the material.

Dates for things in light gray are for planning purposes and are subject to change.
