+ NetPIPE is a protocol independent performance tool that visually
+ represents the network performance under a variety of conditions. It
+ performs simple ping-pong tests, bouncing messages of increasing size
+ between two processes, whether across a network or within an SMP
+ system. Message sizes are chosen at regular intervals, and with slight
+ perturbations, to provide a complete test of the communication system.
+ Each data point involves many ping-pong tests to provide an accurate
+ timing. Latencies are calculated by dividing the round trip time in
+ half for small messages ( < 64 Bytes ).
