Dr. James Anderson, Lecturer in Computer Science, Reading University
Thursday 16th June 2011 – 7:30pm
Venue: Oxford e-Research Centre, 6 Keble Road, Oxford, OX1 3QG
Abstract: The operations of a total arithmetic can be applied to any numbers with the result being a number. Such arithmetics have no arithmetical exceptions so they can be executed in a pipeline without stalling. If a program’s inner loops can be unrolled to an inline program then that program can be executed in a pipeline with a number of program runs completing each clock tick. In a practical molecular dynamics problem, 500 atom-atom interactions were computed each clock tick in a simulated 2M core machine.
The talk will begin with an introduction to transreal arithmetic and show how it can be implemented in both integer and floating-point arithmetic, with special emphasis on IEEE floating-point arithmetic. Transcomplex arithmetic, and its application to the solution of physical problems, will be discussed very briefly, before showing how to exploit the arithmetics in a massively pipelined machine.
