Abstract

Implementation of a new dataflow schedule model is the objective of this thesis. The dataflow model algorithm called the resource/dataflow graph model is implemented on a peer-to-peer communication network comprising of six personal computers. This dataflow model is implemented making use of an earlier dataflow model called ATAMM (Algorithm to Architecture Mapping Model) developed by ODU and National Aeronautics and Space Administration (NASA). Development issues include modification of the RDFG testbed operating system and a scheme to transfer data buffers using the ethernet channel from one processor to another processor. This, in turn, equips each sub-module of an application with the ability to transfer computed data in the reduced time between them, which is an essential part for any dataflow algorithm to be productive. Additional issues built over this underlying dataflow algorithm include the development of an algorithm to synchronize the local clocks in the multicomputer testbed in an effort to create a global clock for event time markings. Experiments were conducted on the resource/dataflow operating system testbed to demonstrate the behavior and performance of the model.
