DiP : A parallel program development environment

Abstract

This paper describes an environment whose aim is to aid in the development and tuning of message passing applications before actually running them in a real system with a large number of processors. Our objective is not to eliminate tests on reed machines but to be able to focus them in a more selective way and thereby minimize their number. The environment presented in this paper consists of three closely integrated tools: an instrumented communication library, a trace driven simulator (Dimemas) and a visualization/analysis tool (Paraver).
