Abstract

The emergence of multi-core processors has led to the expansion of parallel programming in all areas. OpenMP appears to be one of the most suitable API for new processor architectures. This choice is justified by its ease of use compared to other alternatives of parallel programming. However, due to many factors, developing efficient OpenMP programs is a challenging task. In this work, we present a new performance model dealing with performance modeling of OpenMP programs on multi-core machines. Experimental results achieved on a matrix-matrix product prove the simplicity and the accuracy of the predicted performance given by the model.
