Parallel and distributed systems: UML based modeling of performance oriented parallel and distributed applications

ABSTRACT

In this paper we introduce a novel approach for modeling performance oriented distributed and parallel applications based on the Unified Modeling Language (UML). We utilize the UML extension mechanisms to customize UML for the domain of performance oriented distributed and parallel computing. A set of UML building blocks is described that model some of the most important constructs of message passing and shared memory parallel paradigms which can be used to develop models for large and complex parallel and distributed applications. We illustrate our approach by modeling a parallel many-body physics application that combines message passing and shared memory parallelism.
