STARTPAR(8)STARTPAR(8)NAME
startpar - start runlevel scripts in parallel
SYNOPSIS
startpar [-p par] [-i iorate] [-t timeout] [-T global_timeout] [-a arg]
prg1 prg2 ...
startpar [-p par] [-i iorate] [-t timeout] [-T global_timeout] -M [
boot|start|stop]
DESCRIPTION
startpar is used to run multiple run-level scripts in parallel. The
degree of parallelism on one CPU can be set with the -p option, the
default is full parallelism. An argument to all of the scripts can be
provided with the -a option. Processes blocked by pending I/O will
cause new process creation to be weighted by the iorate factor 800. To
change this factor the option -i can be used to specify another value.
The amount weight=(nblocked×iorate)/1000 will be subtracted from the
total number of processes which could be started, where nblocked is the
number of processes currently blocked by pending I/O.
The output of each script is buffered and written when the script
exits, so output lines of different scripts won't mix. You can modify
this behaviour by setting a timeout.
The timeout set with the -t option is used as buffer timeout. If the
output buffer of a script is not empty and the last output was timeout
seconds ago, startpar will flush the buffer.
The -T option timeout works more globally. If no output is printed for
more than global_timeout seconds, startpar will flush the buffer of the
script with the oldest output. Afterwards it will only print output of
this script until it is finished.
The -M option switches startpar into a make(1) like behaviour. This
option takes three different arguments: boot, start, and stop for read‐
ing .depend.boot or .depend.start or .depend.stop respectively in the
directory /etc/init.d/. By scanning the boot and runlevel directories
in /etc/init.d/ it then executes the appropriate scripts in parallel.
