#Distributed System Course List

##Systems

• Cornell CS 614 - Advanced Course in Computer Systems - Ken Birman teaches this course. The readings cover more distributed systems research than is typical (which I am in favour of!). In fact, there's barely anything on traditional internal OS topics like filesystems or memory management. There's some worthwhile commentary at the bottom of the page.

• Princeton COS 518 - Advanced Operating Systems - short and snappy reading list of two papers per topic, covering some interesting stuff like buffering inside the operating system, and L4.

• Stanford CS240 - Advanced Topics in Operating Systems - an interesting and concise set of readings. A presentation on Firefox internals is a course-specific highlight.

• Harvard CS264 - Peer-to-Peer Systems - No notes but a useful collection of papers surveying from CAN and Chord to Skype.

• CSE 552 - Distributed Systems - University of Washington graduate distributed systems course. Thoughtfully selected readings.

• CMU 15-712 - Advanced and Distributed Operating Systems

• UIUC CS 525 - Advanced Distributed Systems - long list of readings, drawn mostly from the last ten years or so, focusing on applications.

• Cornell CS6452 - Datacenter Networks and Services - networking focused - but by no means exclusively.

##Databases

[] Brown CSCI 2270 - Advanced Topics in Database Management - no notes but a good set of [] readings. Does a good job of categorising the last ~15 years of distributed and parallel database research which has moved away from shared-something RDBMSs.

##Distributed Algorithms

• MIT 6.852 - Distributed Algorithms - Goodish lecture slides, detailed but manageable set of readings and some homework problems. Lectured by Professor Lynch at MIT, who literally wrote the book on the subject.

[] Distributed Algorithms Lecture Notes - Very readable set of lecture notes on distributed algorithms, for a course given in 1993 at the Technion in Israel (I think).

[] MIT 6.885 - Distributed Algorithms for Mobile Wireless Ad-Hoc Networks - One of the only courses on this particular niche subject. Taught simultaneously by Jennifer Welch and Nancy Lynch. Notes are very good, reading lists is very comprehensive and there are also some good handouts!

##Data Structures and Algorithms

• MIT 6.854J (OCW) - Advanced Algorithms - A good first course after familiarity with Cormen et. al. is achieved. Topics include competitive queues, splay trees, six lectures on flow algorithms, linear programming and computational geometry. Lecturer's own notes are sparse, but the scribed notes are very useful.

• MIT 6.851 - Advanced Data Structures - supercedes the below course I think, both taught by the legendary Erik Demaine. Worth keeping the below one around as well, since the notes are slightly different as are the topics covered.

• MIT 6.897 - Advanced Data Structures - good coverage of advanced topics including dynamic graphs, succinct data structures and data structures for integers. Scribe notes are excellent, lecturer's own hand-written notes less so.

• Chicago CS369E - Expanders in Computer Science - graduate level course on expander graphs and their applications to computer science. Notes are excellent.

• Harvard CS225 - Pseudorandomness - good scribe notes, covers randomized algorithms, quite a lot on expander graphs etc.

• Yale 500A - Spectral Graph Theory and its Applications - slightly rambling but clear and interesting lecturer written notes.

[] UIUC CS573: Algorithmic Game Theory - good scribe notes and a pointer to a massive online text book.

• Cornell CS683 - Advanced Algorithms - detailed web page, notes and readings. Focus is on approximation algorithms, linear programming and randomisation.

• Wisconsin CS787 - Advanced Algorithms - decent notes and readings. Linear programming, network flows, approximation and randomisation, plus some interesting stuff on online algorithms.

• UIUC CS 373 - Combinatorial Algorithms - a senior undergraduate course in mainly advanced topics from CLRS with outstanding notes.

##Discrete Mathematics and Probability

• MIT 6.042J (OCW) - Elementary discrete maths, including graph theory and some combinatorics. Lecture slides are available, and good, but the real meat is in the readings.

#Paper List
