format: Lava-Test Test Definition 1.0
name: hackbench
description: "Hackbench is both a benchmark and a stress test for the Linux
kernel scheduler. It's main job is to create a specified
number of pairs of schedulable entities (either threads or
traditional processes) which communicate via either sockets or
pipes and time how long it takes for each pair to send data
back and forth."

params:
ITERATION: "1000"
TARGET: "host"
# Sets the amount of data to send in each message
DATASIZE: "100"
# How many messages each sender/receiver pair should send
LOOPS: "100"
# Defines how many groups of senders and receivers should be started
GRPS: "10"
# Defines how many file descriptors each child should use. Note that the
# effective number will be twice the amount you set here, as the sender
# and receiver children will each open the given amount of file descriptors.
FDS: "20"
# Sends the data via a pipe instead of the socket (default)
PIPE: "false"
# Each sender/receiver child will be a POSIX thread of the parent.
# The default is to run in process mode (-P)
THREADS: "false"
