Abstract

Efficiency and scalability are two key concepts for analyzing the performance of parallel systems. Even though heterogeneous systems are becoming more common, there are no suitable definitions of similar concepts for studying their behaviour. This paper first presents a definition of efficiency that can be applied equally to heterogeneous and homogeneous systems. From that definition, the paper also presents an extension of the isoefficiency method that permits its application to heterogeneous environments as well. Finally the paper presents some experiments where the methods' usefulness and validity are shown.
