Model-driven monitoring support for the multi-view performance analysis ofparallel embedded applications

This paper describes an approach to carry out performance analysis of paral lel embedded applications. The approach is based on measurement, but in add ition, the idea of driving the measurement process (application instrumenta tion and monitoring) by a behavioral model is introduced. Using this model, highly comprehensible performance information can be collected. The whole approach is based on this behavioral model, one instrumentation method and two tools, one for monitoring and the other for visualization and analysis. Each of these is briefly described, and the steps to carry out performance analysis using them are clearly defined. They are explained by means of a case study. Finally, one method to evaluate the intrusiveness of the monito ring approach is proposed, and the intrusiveness results for the case study are presented. (C)2000 Elsevier Science B.V.
