Subject: [sched/numa] 5278ba412f: unixbench.score -2.9% regression
Greeting,
FYI, we noticed a -2.9% regression of unixbench.score due to commit:
commit: 5278ba412faff8402e318ad20ab762cc9ba7a801 ("[PATCH 3/4] sched/numa: Apply imbalance limitations consistently")
url: https://github.com/intel-lab-lkp/linux/commits/Mel-Gorman/Mitigate-inconsistent-NUMA-imbalance-behaviour/20220520-183837
base: https://git.kernel.org/cgit/linux/kernel/git/tip/tip.git 991d8d8142cad94f9c5c05db25e67fa83d6f772a
patch link: https://lore.kernel.org/lkml/20220520103519.1863-4-mgorman@techsingularity.net
in testcase: unixbench
on test machine: 128 threads 2 sockets Intel(R) Xeon(R) Gold 6338 CPU @ 2.00GHz with 256G memory
with following parameters:
runtime: 300s
nr_task: 1
test: shell1
cpufreq_governor: performance
ucode: 0xd000331
test-description: UnixBench is the original BYTE UNIX benchmark suite aims to test performance of Unix-like system.
test-url: https://github.com/kdlucas/byte-unixbench
In addition to that, the commit also has significant impact on the following tests:
+------------------+---------------------------------------------------------------------------------+
| testcase: change | unixbench: unixbench.score -11.1% regression |
| test machine | 128 threads 2 sockets Intel(R) Xeon(R) Gold 6338 CPU @ 2.00GHz with 256G memory |
| test parameters | cpufreq_governor=performance |

| | runtime=300s |
| | test=shell8 |
| | ucode=0xd000331 |
+------------------+---------------------------------------------------------------------------------+
If you fix the issue, kindly add following tag
Reported-by: kernel test robot <oliver.sang@...el.com>
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.
