Subject: [sched/fair] ae44f2177f: reaim.jobs_per_min 2.3% improvement
Greeting,
FYI, we noticed a 2.3% improvement of reaim.jobs_per_min due to commit:
commit: ae44f2177fa75c271734d5963972faecc3686c12 ("[RFC v2 2/2] sched/fair: introduce sched-idle balance")
url: https://github.com/intel-lab-lkp/linux/commits/Abel-Wu/introduece-sched-idle-balance/20220409-215303
base: https://git.kernel.org/cgit/linux/kernel/git/tip/tip.git 089c02ae2771a14af2928c59c56abfb9b885a8d7
patch link: https://lore.kernel.org/lkml/20220409135104.3733193-3-wuyun.abel@bytedance.com
in testcase: reaim
on test machine: 16 threads 1 sockets Intel(R) Xeon(R) E-2278G CPU @ 3.40GHz with 32G memory
with following parameters:
runtime: 300s
nr_task: 100%
test: new_fserver
cpufreq_governor: performance
ucode: 0xec
test-description: REAIM is an updated and improved version of AIM 7 benchmark.
test-url: https://sourceforge.net/projects/re-aim-7/
Details are as below:
-------------------------------------------------------------------------------------------------->
To reproduce:
git clone https://github.com/intel/lkp-tests.git
cd lkp-tests
sudo bin/lkp install job.yaml # job file is attached in this email
bin/lkp split-job --compatible job.yaml # generate the yaml file for lkp run
sudo bin/lkp run generated-yaml-file
# if come across any failure that blocks the test,
# please remove ~/.lkp and /lkp dir to run from a clean state.
