Themes to which this unit belongs
  • Computer Architecture


Due to technological limitations, it is proving increasingly difficult to maintain a continual increase in the performance of individual processors. Therefore, the current trend is to integrate multiple processors on to a single chip and exploit the resulting parallel resources to achieve higher computing power. However, this may require significantly different approaches to both hardware and software particularly for general purpose applications. This course will explore these issues in detail.



Trends in technology, limitations and consequences. The move to multi-coreParallelism in programs, ILP, Thread Level, Data Parallelism.

Parallel Architectures

SIMD, MIMD, Shared Memory, Distributed Memory, strengths and weaknesses.

Parallel Programming

Multithreaded programming, Data parallel programming, Explicit vs Implicit parallelism, automatic parallelisation. The Case for Shared Memory. When to share?

Shared Memory Multiprocessors

Basic structures, the cache coherence problem. The MESI protocol. Limitations. Directory based coherence.

Programming with Locks and Barriers

The need for synchronisation. Problems with explicit synchronisation

Other Parallel Programming Approaches

MPI and OpenMP


The easy route to automatic parallelisation?

Transactional Memory

Principles. Hardware and Software approaches

Memory Issues

Memory system design. Memory consistency

Other Architectures and Programming Approaches


Data Driven Parallelism

Dataflow principles and Functional Programing

Feedback methods

Written feedback on reports for laboratory exercises. Students who attempt previous exam questions can get feedback on their answers.
