COS 417: Operating Systems

Course Staff:

Profs: Mae Milano and Amit Levy

TAs: A Zhou, A Zhang, P Wang

Course Description:

This course provides a comprehensive introduction to the principles and practice of operating systems. We will cover topics such as processes, virtualization, memory management, concurrency, and I/O. The course will emphasize both theoretical foundations and practical implementation.

Course Objectives:

• Understand the fundamental concepts of operating systems

• Gain experience in designing and implementing operating systems components

• Develop skills in analyzing and evaluating operating systems performance

• Appreciate the role of operating systems in modern computing environments

Textbook:

Operating Systems: Three Easy Pieces by Remzi H. Arpaci-Dusseau and Andrea C. Arpaci-Dusseau

Grading:

Homework (10%) Programming Assignments (40%) Midterm Exam (25%) Final Exam (25%)

Late Policy:

Summary: you have 3 late days; default penalty is 10% per day (after late days are applied).

Detail:

By default, each day (24-hour period) an assignment is late will incur a 10% late penalty. Late penalties are not pro-rated; an assignment submitted n*24 + m (where 0 < m < 24) hours late will receive n+1 days of penalty.

Up to three assignments may be submitted up to 24-hours late without penalty, via our “late day” policy.

Late day policy: Each student is allocated three “late days.” Each “late day” grants the ability to submit an assignment 24 hours late, without late penalty. The course staff will optimally allocate late days at the end of the semester, to minimize late penalties incurred on all assignments.

Academic Integrity:

Academic integrity is taken very seriously by COS 417; a detailed policy, including references to chatGPT, is forthcoming
