lat_fifo - FIFO benchmark
lat_ctx [ -P <parallelism> ] [ -W <warmups>
] [ -N <repetitions> ]
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.
Funding
for the development of this tool was provided by Sun Microsystems Computer
Corporation.
