Subject: [sched/fair] b4d95a034c:
phoronix-test-suite.tiobench.RandomWrite.64MB.8.mb_s -26.3% regression
Greeting,
FYI, we noticed a -26.3% regression of phoronix-test-suite.tiobench.RandomWrite.64MB.8.mb_s due to commit:
commit: b4d95a034cffb1e4424874645549d3cac2de5c02 ("[PATCH 2/2] sched/fair: Adjust the allowed NUMA imbalance when SD_NUMA spans multiple LLCs")
url: https://github.com/0day-ci/linux/commits/Mel-Gorman/Adjust-NUMA-imbalance-for-multiple-LLCs/20211125-232336
base: https://git.kernel.org/cgit/linux/kernel/git/tip/tip.git 8c92606ab81086db00cbb73347d124b4eb169b7e
in testcase: phoronix-test-suite
on test machine: 96 threads 2 sockets Intel(R) Xeon(R) Gold 6252 CPU @ 2.10GHz with 128G memory
with following parameters:
test: tiobench-1.3.1
option_a: Random Write
option_b: 64MB
option_c: 8
cpufreq_governor: performance
ucode: 0x5003006
test-description: The Phoronix Test Suite is the most comprehensive testing and benchmarking platform available that provides an extensible framework for which new tests can be easily added.
test-url: http://www.phoronix-test-suite.com/
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.
