Carsten, The Intel MPI Benchmarks (formerly Pallas MPI Benchmarks) are a good choice for measuring a range of MPI driven network performance features. There is a nice technical summary defining exactly what is being measured and how.
They are at: http://www.intel.com/cd/software/products/asmo-na/eng/cluster/clustertoolkit/219848.htm Enjoy! rbw -- "Making predictions is hard, especially about the future."
