MPI Multicore Torus Communication Benchmark
Schulz, M. · OSTI OAI (U.S. Department of Energy Office of Scientific and Technical Information) · 2008
The MPI Multicore Torus Communications Benchmark (TorusTest) measures the aggregate bandwidth across all six links from/to any multicore node in a logical torus. It can run in wo modi: using a static or a random mapping of tasks to torus locations. The former can be used to achieve optimal mappings and aggregate bandwidths that can be achieved with varying node mappings.
