Abstract

It can be very difficult to know just what is going on inside your Transputers. Are they executing efficiently, or are they spending all their time waiting? And if so, just who is waiting where for whom?

All this assumes you have some program running. But what if your problem is more fundamental? How good are different algorithms for solving a problem? How does changing the topology affect the performance of an algorithm?

These questions need to be answered, and answering them needs tools. ParSiFal is an Alvey backed collaborative project to build Transputer-based hardware and occam-based software tools. The aim is to help researchers, analysts and programmers gain the insight they need to understand, design and write parallel programs.
