Research Interests

Following retirement, I am no longer active in research (so will not be supervising any more students or visitors) but still maintain an interest in HASE, a Hierarchical computer Architecture design and Simulation Environment we developed at Edinburgh. This environment is effectively a virtual laboratory for research in computer architecture. It has been used for a number of major projects:

HASE has also been used as the development environment for a number of undergraduate and postgraduate projects. It can be run on Linux, MACs and Windows and can be downloaded from the HASE website. The source code for a number of models that can be use to support the teaching of computer architecture is also available from the Computer Architecture Simulation Models website. The most recently completed models are of the Ferranti Atlas Computer, built for the December 2012 50th Anniversary of the Atlas Computer celebration at The University of Manchester, and its successor at Manchester, the MU5 computer.


High Performance Computer Architectures - a Historical Perspective is an on-line resource being developed from the textbook "Architecture of High Performance Computers" by Roland N. Ibbett and Nigel P. Topham, originally published in two volumes by Macmillan Educational Ltd.
