LAT_FIFO(8)                         LMBENCH                        LAT_FIFO(8)


NAME

       lat_fifo - FIFO benchmark


SYNOPSIS

       lat_ctx [ -P <parallelism> ] [ -W <warmups> ] [ -N <repetitions> ]


DESCRIPTION

       lat_fifo is a client/server program that measures interprocess
       communication latencies.  The benchmark passes a message 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.  The message is passed back and forth using FIFOs.


ACKNOWLEDGEMENT

       Funding for the development of this tool was provided by Sun
       Microsystems Computer Corporation.
