Abstract

This paper presents an extension of Dimemas to enable accurate performance prediction of message passing applications with collective communication primitives. The main contribution is a simple model for collective communication operations that can be user-parameterized. The experiments performed with a set of MPI benchmarks demonstrate the utility of the model.
