Subject: [PATCH tip/core/rcu 15/20] torture: Add --dryrun batches to help schedule a distributed run
Date: Wed, 6 Jan 2021 09:26:02 -0800 [thread overview]
Message-ID: <20210106172607.22816-15-paulmck@kernel.org> (raw)
In-Reply-To: <20210106172547.GA22404@paulmck-ThinkPad-P72>
From: "Paul E. McKenney" <paulmck@kernel.org>
When all of the remote systems have the same number of CPUs, one
approach is to use one "--buildonly" run and one "--dryrun sched" run,
and then distributing the batches out one per remote system. However,
the output of "--dryrun sched" is not made for parsing, so this commit
adds a "--dryrun batches" that provides the same information in easily
parsed form.
