Subject: [linus:master] [sched/fair] 829c1651e9: hackbench.throughput -7.9%
regression
Greeting,
FYI, we noticed a -7.9% regression of hackbench.throughput due to commit:
commit: 829c1651e9c4a6f78398d3e67651cef9bb6b42cc ("sched/fair: sanitize vruntime of entity being placed")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: hackbench
on test machine: 104 threads 2 sockets (Skylake) with 192G memory
with following parameters:
nr_threads: 100%
iterations: 4
mode: process
ipc: socket
cpufreq_governor: performance
In addition to that, the commit also has significant impact on the following tests:
+------------------+------------------------------------------------------------------------------------------------+
| testcase: change | stress-ng: stress-ng.rawudp.ops_per_sec 74.0% improvement |
| test machine | 88 threads 2 sockets Intel(R) Xeon(R) Gold 6238M CPU @ 2.10GHz (Cascade Lake) with 128G memory |
| test parameters | class=network |
| | cpufreq_governor=performance |
| | nr_threads=100% |
| | test=rawudp |
| | testtime=60s |
+------------------+------------------------------------------------------------------------------------------------+
| testcase: change | hackbench: hackbench.throughput 125.5% improvement |
| test machine | 88 threads 2 sockets Intel(R) Xeon(R) Gold 6238M CPU @ 2.10GHz (Cascade Lake) with 128G memory |

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.
