Subject: [LKP] [rcu] 7e28c5af4e: will-it-scale.per_process_ops 84.7%
improvement
Greeting,
FYI, we noticed a 84.7% improvement of will-it-scale.per_process_ops due to commit:
commit: 7e28c5af4ef6b539334aa5de40feca0c041c94df ("rcu: Eliminate ->rcu_qs_ctr from the rcu_dynticks structure")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: will-it-scale
on test machine: 288 threads Intel(R) Xeon Phi(TM) CPU 7295 @ 1.50GHz with 80G memory
with following parameters:
nr_task: 100%
mode: process
test: brk1
cpufreq_governor: performance
test-description: Will It Scale takes a testcase and runs it from 1 through to n parallel copies to see if the testcase will scale. It builds both a process and threads based test in order to see any differences between the two.
test-url: https://github.com/antonblanchard/will-it-scale
Details are as below:
-------------------------------------------------------------------------------------------------->
To reproduce:
git clone https://github.com/intel/lkp-tests.git
cd lkp-tests
bin/lkp install job.yaml # job file is attached in this email
bin/lkp run job.yaml
