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.
