Abstract

Summary SKaMPI is now an established benchmark for MPI implementations. In autumn 2002 the development of the “new SKaMPI” has started in three major directions: (i) extension of the benchmark to cover more functions of MPI and a redesign of the benchmark allowing it to be extended more easily (thus matching requests from SKaMPI users); (ii) construction of a collection of important algorithm kernels which are not supported by core MPI collective operations; (iii) development of a simulator which (at least partially) supports the simulation of one MPI implementation while using another MPI implementation (possibly running on a different kind of machine). In the present paper we give an overview of the new SKaMPI and describe fast implementations of MPI_Alltoall and of an algorithm for transposing multidimensional matrices as first instances of SKaMPI-Alg.
