摘要: In this article we present a novel approach to analyzing performance properties of parallel applications based on event traces. We define framework for formally specifying compound events that characterize behavior. The allows the creation abstract building blocks represent concepts underlying programming model and therefore provide an easy means specify complex events. show using these specifications it is possible automatically locate inefficiencies in by looking occurrences corresponding demonstrate how our ideas apply both Message Passing Interface (MPI) Open Multi Processing (OpenMP).
