Subject: [NUMA Balancing] e39bb6be9f: will-it-scale.per_thread_ops 64.4%
improvement
Greeting,
FYI, we noticed a 64.4% improvement of will-it-scale.per_thread_ops due to commit:
commit: e39bb6be9f2b39a6dbaeff484361de76021b175d ("NUMA Balancing: add page promotion counter")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: will-it-scale
on test machine: 192 threads 4 sockets Intel(R) Xeon(R) Platinum 9242 CPU @ 2.30GHz with 192G memory
with following parameters:
nr_task: 50%
mode: thread
test: fallocate1
cpufreq_governor: performance
ucode: 0x500320a
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
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.
