Milestone 3 Released and Optional Extra Credit MilestoneWritten on 04.06.26 by Antoine Kaufmann We have now released milestone 3: https://cms.sic.saarland/os_26/5/Course_Project and your milestone 3 repositories should also be created now.

Based on feedback about time spent on the project, we have decided to adjust the plan for the second half: we have removed milestone 4 and extended the time for milestone 3. Milestone 3 carries 2x the weight of the earlier milestones. (total score = (ms1 + ms2 + 2 * ms3) / 4) What we planned as milestone 4, on file systems, is now an optional extra credit milestone available on request (email Antoine). This milestone is not necessary for achieving the full grade, and will be worth 20% extra points. Please carefully consider if you are sufficiently caught up on all material and exam prep before deciding to attempt this. Note that ms4 is at least as much work as ms3. We hope that this will help everyone get more out of this course! |

Operating Systems
This course introduces students to the principles, design, and implementation of operating systems. The lectures focus primarily on the principles and design of operating systems; a series of course projects exposes students to the implementation aspects of operating systems and serves to solidify students' understanding of the course material.
The course grade will be based on a weighted score of the project and the exams (mid-term, and end-term, plus optional repeat).
The course will be taught jointly by Antoine Kaufmann (OS Group), Björn Brandenburg, Laurent Bindschaedler (DSG Group) from MPI-SWS.
You can find the previous iterations here and here, if you are curious. Some pieces will change, but overall the spirit and core ideas will remain the same.
Intended Audience / Prerequisites
This core course is open to senior Bachelor, Masters, and doctoral students. Bachelor students must have passed the basic courses on Programming 2 and Math 2 or equivalent (please contact the course staff for more details). Proficiency in programming (C/C++) and UNIX development tools (e.g., make, gcc, gdb) is strictly required to pass this course. Some familiarity with reading assembly code is expected. Be warned, the implementation heavy projects (necessary for passing) in this course, will need a working knowledge of things like memory management and pointers.
The language of the course is English. All lectures, office hours, tutorials, exams and communication with the course staff will be conducted exclusively in English.
