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.
