Subject: cgroup freezer
Date: Mon, 20 Feb 2012 17:50:36 +0800 [thread overview]
Message-ID: <4F42176C.9070709@gmail.com> (raw)
From Documentation/cgroups/freezer-subsystem.txt, the following words
describe the purpose of cgroups freezer:
"The cgroup freezer is useful to batch job management system which start
and stop sets of tasks in order to schedule the resources of a machine
according to the desires of a system administrator."
IMHO, when system load is high, administrator could freeze some of
cpu-hogged tasks in favor of more important ones, once system is most
likely to be idle, frozen tasks could be thaw back on line.
I don't know this idea is right or wrong, can somebody give me some
hints about practical usage of cgroup freezer?
thanks
