MPIBurn

As modern Inter-Connect Hardware handle broadcast messages with different algorithm then unicast messages. Just benchmarking broadcasts or N to N+1 messaging may not detect Inter-Connect-Malfunctions. Therefor MPIBurn benchmarks any possible unicast connection while assuring to involve as many connections in parallel as possible. After each round the peers are scrambled to ensure the next round has complete different connections groups.

Features

• Pattern-less connection groups.
• Max concurrent unicast connections.
• gnuplot friendly statistic output.
