The application is potentially highly parallel but has some unusual features such as rapid spawning of processes in real time and a dynamic inter-process network topology. These characteristics are such as to require enhancement of the usual task migration capabilities of the Globus toolkit. The present paper describes firstly, attempts to estimate the real parallelisability of the scanner application and an effort to develop a Java API based on Milner?s p-calculus which could be used to extend Globus in the manner required to support systems with a dynamic parallel structure. </ABSTRACT></RECORD></RECORDS></XML>
