This is the main website for CSE 401 and CSE M 501. Please use the navigation bar at the top of this page to find important resources and links on this site. Some additional resources, particularly links to lecture recordings, office hours, and the course gradebook, are on the course Canvas web page.
11/21: We will not have a regular class on Wed. Nov. 26, the day before Thanksgiving. Instead, TAs will be available in our regular classroom at that time for extra office hours. The usual Wed. 3:30-4:30 office hours will be canceled that day.
11/20: Backend compiler lectures for Friday and Monday posted.
11/20: Project report descriptions and deadlines for CSE 401 and CSE M 501 added to the calendars.
11/19: HW4, covering dataflow and SSA analysis, is available now. Not due until the last week of classes, but we will have covered the core material by the end of sections tomorrow, so we're making this available now for anyone who wants to get started early.
11/11: Details about the final part of the compiler project, code generation, added to the project web page.
10/28: Information about possible project extensions for CSE M 501 students has been added to the main project index page. If you are in CSE M 501, you and your partner should start thinking now about what you want to do since it may be useful to start working on this as part of the semantics/type-checking part of the overall project.
9/18: Welcome to the website for CSE 401 and CSE M 501 for
Fall Quarter, 2025.
Please send mail to cse401-staff[at]cs if you spot
any unexpected problems.
Instructor: Hal Perkins (perkins[at]cs – but please use cse401-staff[at]cs for mail)
Teaching Assistants: Bill Baxter, Karen Haining, Varun Iyengar, Larry Mei, Rajat Sengupta, and Andy Stanciu. We will also have some help from Alexander Metzger who is the TA for the related CSE P 501 course.
Contact Info: Please use the message board (link at the top of this page) whenever possible. The answer to your question is likely to be helpful to others in the class and, by using the discussion board, it will be available to them as well. Feel free to use private messages on the discussion board for questions that contain detailed code or should not be shared with the rest of the class. For other questions, including unexpected emergencies or other personal circumstances, please send mail to cse401-staff[at]cs (use the same list for CSE M 501). That will help us keep track of things that need further followup from the course staff to better help you.
Lectures: MWF 2:30-3:20 in CSE2 G10. Lectures will be recorded using panopto. See the course canvas page for links. Lecture slides and other items will be posted on the course calendars here, generally by the evening before each class.
Although lectures will be recorded, this class is not a distance-learning or hybrid class. Recordings are intended for review, or to help when unavoidable absences such as illness occur, not to replace class attendance. Recent experience has shown that significant numbers of students who regularly miss class struggle with the material, find it hard to keep up, and do not do as well in the course. You should plan to attend class regularly.
Sections: Various times on Thursday afternoons. Sections will not be recorded, but we may make occasional videos available of tutorial material when helpful. All section materials will be posted on here on the course web site, and you should plan to attend sections regularly.
Office Hours: In-person, zoom, and hybrid at scheduled times during the week. Times and locations will be posted on the main course calendar. Zoom links are on the course canvas calendar page.
