Subject: [bigeasy-staging:futex_local_v4.5] [futex] 51319c5cb6: stress-ng.pthread.ops_per_sec 68.4% regression
Date: Fri, 20 Dec 2024 11:32:06 +0800 [thread overview]
Message-ID: <202412201111.1290bdf8-lkp@intel.com> (raw)
Hello,
kernel test robot noticed a 68.4% regression of stress-ng.pthread.ops_per_sec on:
commit: 51319c5cb6c2f84994a14d11de0fc26321bed99d ("futex: Resize futex hash table based on number of threads.")
https://git.kernel.org/cgit/linux/kernel/git/bigeasy/staging.git futex_local_v4.5
testcase: stress-ng
config: x86_64-rhel-9.4
compiler: gcc-12
test machine: 224 threads 2 sockets Intel(R) Xeon(R) Platinum 8480CTDX (Sapphire Rapids) with 256G memory
parameters:
nr_threads: 100%
testtime: 60s
test: pthread
cpufreq_governor: performance
In addition to that, the commit also has significant impact on the following tests:
+------------------+-----------------------------------------------------------------------------------------------+
| testcase: change | phoronix-test-suite: phoronix-test-suite.hmmer.0.seconds 1.1% improvement |
| test machine | 96 threads 2 sockets Intel(R) Xeon(R) Gold 6252 CPU @ 2.10GHz (Cascade Lake) with 512G memory |
| test parameters | cpufreq_governor=performance |
| | test=hmmer-1.3.0 |
+------------------+-----------------------------------------------------------------------------------------------+
If you fix the issue in a separate patch/commit (i.e. not just a new version of
the same patch/commit), kindly add following tags
| Reported-by: kernel test robot <oliver.sang@intel.com>
| Closes: https://lore.kernel.org/oe-lkp/202412201111.1290bdf8-lkp@intel.com
