Midterm solutions are available from within UCSD.

Lab 4 is cancelled.

CSE 223B is a 4-unit graduate subject with lectures, paper discussions, labs, a midterm, a final, and a term project. It will present abstractions and implementation techniques that facilitate the design of distributed systems---including both operating systems and sophisticated Internet servers---that can deal with the demands of real-world workloads. Topics will include efficient operating system primitives, high-performance network servers, load shedding, storage systems, security, and fault tolerance.

Prereqs: CSE 221 and CSE 222 (or consent of instructor) and substantial programming experience with C/C++ for lab assignments and term project. Note that CSE 223A is not a prerequsite. However, those interested in the theoretical underpinnings of distributed computation are encouraged to take CSE223A as well. CSE223A and CSE223B may be taken in any order.

NB: This course will be a fair amount of work and is not for the faint of heart. It is expected that students signing up for this course are interested in understanding how to design and build research-grade distributed systems. Ideally, students completing the course will be well-prepared to begin research in distributed systems and Internet services. This course will not teach you how to program---you need to know that coming in. This course will teach you how to design and implement real distributed systems.
