Simulation Models of Historical Computers - Atlas, MU5 and CDC 6600
Thu 16th February 2017
BCS, 5 Southampton St, London WC2E 7HA
About the seminar
HASE is a computer architecture simulation environment developed at the University of
A HASE simulation model consists of a file defining the components of the model and their
interconnections, a file defining the screen image of the model, a simulation code file
for each component and files containing the initial values of registers and memories
in the model.
Running a simulation produces a trace file which can subsequently be used to animate
the on-screen display of the model so as to show data movements, parameter value updates,
state changes, etc.
HASE has been used to create models for use in both teaching and research.
More recently it has been used to create simulation models of some historically interesting
computers as a way of bringing them back to (virtual) life: Atlas, MU5 and the CDC 6600.
The talk will include demonstrations of these models.
About the speaker
Roland Ibbett retired from the University of Edinburgh in 2006, where he had been
a professor of Computer Science since 1985.
Prior to that he spent nearly 20 years in the Department of Computer Science at the
University of Manchester, where he was a major contributor to the design and
implementation of MU5.
His interest in high performance architectures continued at Edinburgh where he was a
founder of the Edinburgh Parallel Computing Centre and where his teaching and research
interests led to the creation of the HASE computer architecture simulation environment.
