LAT_PIPE(8) LMBENCH LAT_PIPE(8) NAME lat_pipe - measure interprocess communication latency through pipes SYNOPSIS lat_pipe [ -P <parallelism> ] [ -W <warmups> ] [ -N <repetitions> ] DESCRIPTION lat_pipe uses two processes communicating through a Unix pipe to mea- sure interprocess communication latencies. The benchmark passes a to- ken back and forth between the two processes (this sort of benchmark is frequently referred to as a ``hot potato'' benchmark). No other work is done in the processes. OUTPUT The reported time is in microseconds per round trip and includes the total time, i.e., the context switching overhead is includeded. Output format is like so Pipe latency: 491 microseconds ACKNOWLEDGEMENT Funding for the development of this tool was provided by Sun Microsys- tems Computer Corporation. SEE ALSO lmbench(8).
