Principles of Distributed Computing (FS 2018)

Course catalogue • Previous year • PODC 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.

• Course pre-requisites: Interest in algorithmic problems. (No particular course needed.)
• Course language: English
• Lecture by Roger Wattenhofer and Mohsen Ghaffari, Wednesdays 8-10 in CAB G 11
• Exercises organized by Darya Melnyk (for Prof. Wattenhofer's part), and Manuela Fischer and Jara Uitto (for Prof. Ghaffari's part)
  • Exercise A: Wednesdays 10-12 in CAB G 56
  • Exercise B: Wednesdays 13-15 in LFW C 11
  • Both exercise sessions offer identical content. Please go to the exercise session which better fits your personal schedule.

Exam

• The exam will take place on Monday, August 13, from 9am to 11am in HG G 1.
• You are allowed to bring any written material you like (lecture notes, books, personal notes,...), but no electronic devices whatsoever (no calculator, phone, laptop,...).
• We will do the exam as an online examination. It will take place in a computer room at ETH and you will answer the questions on a computer. There will also be paper available in case you want to draw a picture, write down some formulas or hand in some additional notes which you can't easily type on the computer.
• You will log on to Moodle in order to access the PODC exam on Monday. Please remember to look up your credentials unless you already know them by heart.
• It is not possible to bring your own keyboard, mouse or any other hardware.
• If you have additional questions about the exam, please write an email to Darya.
• We've prepared a Moodle test version of the last year's online exam. You can use this as training material to familiarize yourself with Moodle exams.
• Here are some old exams from previous years: 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2015, 2016, 2017.
