Abstract

SKaMPI is now an established benchmark for MPI implementations. The development of SKaMPI-5 strives for improvements in several directions: (i) extension of the benchmark to cover more functionality of MPI, (ii) construction of a collection of collective algorithm kernels which are not supported by core MPI collective operations. (iii) a redesign of the SKaMPI benchmark allowing it to be extended more easily (thus matching requests from SKaMPI users). In the present paper we give an overview of the extension of SKaMPI for the evaluation of virtual topologies, describe the foundations of new algorithms for fast all-to-all communication specifically tailored for the case of differing message sizes, and give a first impression of what SKaMPI-5 will look like, for which we now have a prototype running.
