Implementing Asynchronous Distributed Systems Using the IOA Toolkit

Unknown author (2004-10-06)

This document is a report about the capabilities and performance of the IOA Toolkit, and in particularthe tools that provide support for implementing and running distributed systems (checker,composer, code generator). The Toolkit compiles distributed systems specified in IOA into Javaclasses, which run on a network of workstations and communicate using the Message Passing Interface(MPI). In order to test the toolkit, several distributed algorithms were implemented, rangingfrom simple algorithms such as LCR leader election in a ring network to more complex algorithmssuch as the GHS algorithm for computing the minimum spanning tree in an arbitrary graph. Allof our experiments completed successfully, and several runtime measurements were made.
