SYNOPSIS
lat_ctx [ -P <parallelism> ] [ -W <warmups> ] [ -N <repetitions> ]
DESCRIPTIONlat_fifo is a client/server program that measures interprocess communi‐
cation 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.
