Principles of Distributed Computing (FS 2020)

Course cataloguePrevious yearPODC lecture collection

Distributed computing is essential in modern computing and communications systems. Examples are on the one hand large-scale networks such as the Internet, and on the other hand multiprocessors such as your new multi-core laptop. This course introduces the principles of distributed computing, emphasizing the fundamental issues underlying the design of distributed systems and networks: communication, coordination, fault-tolerance, locality, parallelism, self-organization, symmetry breaking, synchronization, uncertainty. We explore essential algorithmic ideas and lower bound techniques, basically the "pearls" of distributed computing. We will cover a fresh topic every week.

Exam

Exam preparation

The following parts of the lecture notes have not been covered in the lecture and are therefore not relevant for the exam:

Graded Homework Assignment

We will have two graded homework assignments (compulsory continuous performance assessment). Each graded homework assignment will account for 10% of the final grade, the main exam will be 80% of the final grade.

First Graded Homework Assignment

Corrections of the first graded assignment are now available in moodle. You will find the grading table in the homework description.

Second Graded Homework Assignment

Corrections of the second graded assignment are available in moodle. You will find the grading table in the homework description.


Discussion Forum

We have set up a discussion forum on the moodle course homepage. You can use this forum to ask questions about the homework assignment as well as questions about the lecture. As this is a discussion forum, feel free to also answer the questions of your colleagues.
