Operating System Principles
CSE 30341 is the one of the core classes in the Computer Science and Engineering program at the University of Notre Dame. This course introduces all aspects of modern operating systems. Topics include process structure and synchronization, interprocess communication, memory management, file systems, security, I/O, and distributed files systems.
Upon successful completion of this course, students will be able to:
-
Describe the basic components of a modern operating system.
-
Understand the symbiotic relationship between computer architecture and operating system design.
-
Discuss how operating systems provide abstractions for virtualization, concurrency, and persistence.
-
Construct applications that utilize processes, threads, and sockets to solve problems requiring concurrent or parallel computation.
-
Explain how resources such as memory is allocated and managed by the operating system.
-
Evaluate the trade-offs embedded in different operating system techniques, algorithms, and data structures.
-
Analyze the performance of applications in a variety of system contexts.

Policies
Participation
Students are expected to attend and contribute regularly in class. This means answering questions in class, participating in discussions, and helping other students.
Foreseeable absences should be discussed with the instructor ahead of time.
Academic Honesty
Any academic misconduct in this course is considered a serious offense, and the strongest possible academic penalties will be pursued for such behavior. Students may discuss high-level ideas with other students, but at the time of implementation (i.e. programming), each person must do his/her own work. Use of the Internet as a reference is allowed but directly copying code or other information is cheating. It is cheating to copy, to allow another person to copy, all or part of an exam or a assignment, or to fake program output. It is also a violation of the Undergraduate Academic Code of Honor to observe and then fail to report academic dishonesty. You are responsible for the security and integrity of your own work.
Late Work
In the case of a serious illness or other excused absence, as defined by university policies, coursework submissions will be accepted late by the same number of days as the excused absence.
Otherwise, there is a penalty of 25% per day late (except where noted). You may submit some parts of an assignment on time and some parts late. Each submission must clearly state which parts it contains; no part can be submitted more than once.
Students with Disabilities
Any student who has a documented disability and is registered with Disability Services should speak with the professor as soon as possible regarding accommodations. Students who are not registered should contact the Office of Disabilities.
CSE Guide to the Honor Code
For the assignments in this class, you may discuss with other students and consult printed and online resources. You may quote from books and online sources as long as you cite them properly. However, you may not look at another student's solution, and you may not look at solutions.
For further guidance please refer to the CSE Honor Code or ask the instructor.
