PROGETTO FINALIZZATO SISTEMI INFORMATICI E CALCOLO PARALLELO SOTTOPROGETTO Architetture Parallele Coordinatore

Performance evaluation of parallel systems requires new approaches because of the several di erences from the traditional architectures New methodologies have to be applied also in workload characterization one of the most important aspects of performance evaluation The knowledge of the dynamic behavior of the workload is based on new parameters speci c of parallel environ ments and some changes on traditional analysis are needed A description of these parameters is given explaining the methods for obtaining them and showing their possible uses in parallel systems performance study Some applications based on existing architectures are
