CS3283 Distributed Systems Tutorial on Coordination Some points for further considerations: - Differences between agreement and coordination - The importance of mutual exclusion - Requirements, performance considerations, assumptions and operations for mutual exclusion - The performance of central server method - Assumptions and performance of the ring-based method - Differences between the multicast and Maekawa’s algorithms - What is an election? - The performance of the ring-based method - The assumptions of the Bully algorithm - The purposes and objectives of consensus - The Byzantine General problem and its solution Readings : Dollimore: ch12.1 to ch12.3 and ch12.5 (except 12.5.2 & 12.5.4), Tanenbaum: ch5.4 and ch5.5 Question 1 If we look at the performance of the central server algorithm, it seems that it is simpler in implementation and may give a better performance comparing with multicast algorithm as its number of message for synchronization is similar. Discuss the main performance tradeoffs between the use of central server and the

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
