EE282: Computer Systems Architecture

Winter 2020, Tue/Thu 12:00 PM - 13:20 PM, room Thornt Center 102

Instructor: Christos Kozyrakis
Teaching Assistant: Qian Li
Piazza: Class Homepage

EE282 focuses on key topics in advanced computer systems architecture such as multilevel in memory hierarchies, advanced pipelining and super scalar techniques, vectors, GPUs and accelerators, non-volatile storage and advanced IO systems, virtualization, and datacenter hardware and software architecture. The programming assignments provide an introduction to performance analysis and optimization techniques for computer systems. At the completion of the course, you will understand how computer systems are organized and, why they are organized that way, and what determines their performance. You will also understand the rich interactions between the hardware and software layers in modern systems.
  EE282 is appropriate for undergraduate and graduate students specializing in the broad field of computer systems. It is also appropriate for other EE and CS students who want to understand, program, and make efficient use of modern computer systems of any scale in their day-to-day work.
  Post EE282, students can take CS316, a research seminar on advanced computer architecture based on recent papers, or CS349d, a seminar that covers the software infrastructure of cloud computing and large-scale datacenters.


  • (3/15) (Optional) We just released a sample final. You may skip a question if we didn't cover the material in our class.
  • (3/14) Please read this post for EE282 final exam plan.
  • (3/5) We are providing virtual office hours via Zoom. Please read more details here.
  • (2/26) NVIDIA's Speculative Reconvergence paper is now available online. It was presented on CGO'2020 conference.

SCPD Video Recording Disclaimer: Video cameras located in the back of the room will capture the instructor presentations in this course. For your convenience, you can access these recordings by logging into the course Canvas site. These recordings might be reused in other Stanford courses, viewed by other Stanford students, faculty, or staff, or used for other education and research purposes. Note that while the cameras are positioned with the intention of recording only the instructor, occasionally a part of your image or voice might be incidentally captured. If you have questions, please contact a member of the teaching team.
