Distributed Systems

Instructor

Dr. Janibul Bashir

Course Overview

In this course, we intend to teach the fundamentals of a distributed systems. We will understand the core features and issues associated with distributed systems, and different mechanisms to handle these issues.

Semester Project:

Choose a distributed system (e.g., blockchain, Bittorrent, MapReduce, HDFS, Google BigTable, Spark etc) of your choice and implement it.

Checkpoint 1: Explain the architecture, features, and usefulness of the distributed system that you have chosen. Submit a pdf document of the same. (Deadline 15th April) -- Deadline extended to 19 April 2021.

Checkpoint 2: In your chosen distributed system (in checkpoint 1), explain how they have used clock syncronization (if it is not given, explain how clock is useful in your chosen system). Explain the usefulness of mutual exclusion and leadership in your chosen distributed system.(Deadline 1st June).
