Many challenges arise during the design and implementation of concurrent and distributed programs. The aim of this course is to understand those challenges, and to see techniques for tackling them. The main paradigm to be considered is message passing concurrency, where independent processes, with private variables, interact by passing messages.

Learning outcomes

At the end of the course students are expected to understand:
  • The conceptual foundations of concurrent programming, and
  • A variety of effective ways of structuring concurrent and distributed programs.


This course combines well with the Concurrency course: Concurrent Programming helps provide motivation for Concurrency, while Concurrency helps to provide formal underpinnings for this course. 

Students should have a basic understanding of Object Oriented Programming (objects, classes, interfaces, inheritance, abstract classes, polymorphism), and be comfortable with programming in Scala. Although the methods of reasoning used in the course will be informal, students should be broadly familiar with the notions of pre- and post-condition, invariant, and abstraction function.

The course will have a number of practicals, to allow students to gain experience with concurrent programming. These practicals will use Scala.


A detailed synopsis summarising the running order and content of lectures to be given in HT 2017-18 appears in the Lectures section of the course materials site.


Reasons for concurrency; processes, threads; safety and liveness. Message passing concurrency; deadlock. Clients and servers. Interacting peers.  Synchronous parallel computation.  Patterns of concurrent programming: data parallel; bag of tasks; recursive parallel; task parallel.  Low-level concurrency controls: monitors; semaphores.
