I have an LVS/DR cluster of 10 machines that receive similar traffic
via a round-robin strategy. These machines run Debian Lenny with
2.6.26, and consistently have a 15-minute load average between 4-12
depending on the time of day.
Upgrading any one of these machines to a newer kernel compiled with
NO_HZ=y causes the reported load average to drop significantly. Here,
fe3 and fe12 are running 3.2.4:
fe3: 0.48 0.53 0.55
fe4: 6.73 5.59 5.11
fe5: 5.93 5.29 5.60
fe6: 6.20 5.79 6.08
fe7: 8.32 5.65 5.05
fe8: 6.34 5.85 5.93
fe9: 5.80 5.46 5.53
fe10: 5.49 4.91 5.03
fe11: 6.60 6.11 6.10
fe12: 0.39 0.54 0.46
The newly reported load average is much lower than the other machines
performing equivalent work, and does not match cpu usage numbers
reported by vmstat.
Originally, I attempted to upgrade to 2.6.32 (used by lenny-backports
and squeeze). In 2.6.32, load averages are misreported even when using
NO_HZ=n. This bug was fixed in 2.6.34-rc4 (74f5187ac8: sched: Cure
load average vs NO_HZ woes).
The NO_HZ=y case was supposed to be fixed in 2.6.37-rc5 (0f004f5a69:
sched: Cure more NO_HZ load average woes), with the commit stating
"behaviour between CONFIG_NO_HZ=[yn] should be equivalent". In my
environment, however, kernels after this patch was introduced still
misreport load averages when compiled with NO_HZ=y.
Here's a list of the kernel versions I've tried (more details in
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=620297):
Correct Load Average
2.6.26.25
2.6.32.55-620297patch (CONFIG_NO_HZ=n)
Incorrect Load Average
2.6.32-bpo.5-amd64
2.6.32.55
2.6.32.55-620297patch
2.6.32.55-620297patch (nohz=off)
2.6.37-rc5-cure-more
2.6.39.4
3.2.2
3.2.4
Also worth nothing is that fe12 is much newer than fe3, which should
help rule out hardware as a cause of this bug.
fe3: Dell PowerEdge 2950 w/ Xeon(R) CPU L5420 @ 2.50GHz
fe12: Dell PowerEdge R710 w/ Xeon(R) CPU E5645 @ 2.40GHz
I've attached dmesg output from fe12 booting up on 3.2.4. I am happy
to provide any other information that would be useful, and would
appreciate any advice on patches to try or ways to narrow the bug down
further.

[...] I can confirm Aman's results on kernels 2.6.32 and higher on a similar setup. I did a test on a cluster of diskless PHP workers. Servers were running on identical hardware and software platform. The workload should have been the same. However load average was reporting different values depending on which kernel the host was running. I have tested the following vanilla kernels: * 2.6.32.55-* * 2.6.32.55-*-74f5187ac8 (2.6.32.55 with patch 74f5187ac8) * 2.6.32.55-*-0f004f5a69 (2.6.32.55 with patch 74f5187ac8 and 0f004f5a69) * 2.6.37-rc5-*-0f004f5a69 (2.6.37 at commit 0f004f5a69) * 2.6.37-rc5-*-pre-0f004f5a69 (2.6.37 at commit 6313e3c217) Each kernel was compiled with CONFIG_NO_HZ enabled (no-hz variant) and disabled (hz variant). Here's a snapshot of load 15 on each kernel: no-hz hz 2.6.32.55-* 0.59 0.57 2.6.32.55-*-74f5187ac8 3.56 11.79 2.6.32.55-*-0f004f5a69 0.61 11.76 2.6.37-rc5-*-0f004f5a69 0.67 11.65 2.6.37-rc5-*-pre-0f004f5a69 3.97 12.05 I've also uploaded load average [1] and CPU utilization [2] charts for a visual comparison. My observations are: 1. On tickless kernels load is very low where no or both patches (74f5187ac8 and 0f004f5a69) are applied. 2. Kernels that have only patch 74f5187ac8 applied have the smallest difference between hz and no-hz variants. Still no-hz kernels are returning values lower than their hz siblings. 3. Non-tickless kernels seem to be reporting correct load values. Overall trend and values are matching CPU utilization. Only exception is 2.6.32.55-hz which reports the same values as 2.6.32.55-no-hz. 4. If x processes are using all available cycles load is correctly incremented by x. This behavior is consistent on all kernels. Steps to reproduce: run a bunch of CPU bound processes that will not use all available cycles. The biggest difference between expected and measured load is around 30% CPU utilization in my case. Has there been any other patches that correct load calculation? Maybe I'm testing it in a wrong way? I'd appreciate any suggestions. I'd be happy to test new patches. Sadly, I cannot propose any fixes as kernel sources are still a mystery to me.

This behavior is consistent on all kernels. Yay! at least we get something right..

Hrmm, this suggests we age too hard with nohz code.. in your test case is there significant idle time? That is, suppose you run each cpu at 30% what is the period of you load?

I can indeed see some weirdness, but not only downwards, I can manage to get a load of 1 with two 20% burners (0.1 ms period).

You've asked for it and you got it. I have rebooted some servers with nohz=off parameter set on kernels complied with CONFIG_NO_HZ=y. They're the ones listed below with 'off' suffix.

It's definitely more similar to the second case - very frequent, but short bursts of activity. A single process does a tiny bit of computation mixed with a fair amount of network activity on each request. There are 80 such processes which are responsible for majority of system load.

The only difference was the patch had to go to kernel/sched.c, but that's what you get when not using the latest sources. Anyway, here are the results accompanied by a pretty picture [1]: std off patch0 2.6.32.55-no-hz 0.76 0.91 - 2.6.32.55-no-hz-74f5187ac8 6.41 9.40 4.93 2.6.32.55-no-hz-0f004f5a69 0.78 0.92 0.90 2.6.37-rc5-no-hz-0f004f5a69 0.95 0.92 0.86 2.6.37-rc5-no-hz-pre-0f004f5a69 9.16 10.47 8.02 It seems that the patch didn't help much on kernels with 0f004f5a69 applied. The ones with just 74f5187ac8 are reporting a more plausible values, but slightly lower than the ones without patch0. Am I right to assume that the correct load values are the ones produced by kernels complied with CONFIG_NO_HZ=n? Should they be the baseline? I can run additional tests if you have other leads to follow. Is there a particular kernel version I should focus on? If not I will continue to use the current bundle. I'm also planning to give the latest stable release a spin.

The below patch appears to sort the issue, but I haven't been able to test the very long idle path simply because x86 doesn't go idle that long. I tried writing hpet64 support so we could idle that long, killed all kinds of stupid kernel threads (watchdogs mostly) that keep waking up and got a brick.. Clearly I need to try again... but I thought I'd at least share this stuff. --- Subject: sched: Fix nohz load accounting -- again! From: Peter Zijlstra <peterz@infradead.org> Date: Thu, 01 Mar 2012 15:04:46 +0100 Various people reported nohz load tracking still being wrecked, but Doug spotted the actual problem. We fold the nohz remainder in too soon, causing us to loose samples and under-account. So instead of playing catch-up up-front, always do a single load-fold with whatever state we encounter and only then fold the nohz remainder and play catch-up.

I've finally finished testing patch c308b56b53. Apologies for the delay in reporting back. This time I've compared kernels from 3.2 and 2.6.32 branches. Here's a snapshot of load 15 on different versions: 2.6.32.55-hz-0f004f5a69 12.78 2.6.32.55-no-hz-74f5187ac8 4.42 2.6.32.55-no-hz-0f004f5a69 0.49 2.6.32.55-no-hz-c308b56b53 4.37 3.2.12-hz 12.85 3.2.12-no-hz 0.65 3.2.12-no-hz-c308b56b53 7.25 3.2.12-no-hz-c308b56b53 nohz=off 10.59 A whole day trend is available on a comparison chart [1]. Just to make things clear 2.6.32 kernels were patched as follows: * 74f5187ac8 - just 74f5187ac8 * 0f004f5a69 - 74f5187ac8 + 0f004f5a69 * c308b56b53 - 74f5187ac8 + 0f004f5a69 + c308b56b53 For kernel 3.2.12 patch c308b56b53 seems almost perfect. For low CPU utilization the load value is slightly lower for NO_HZ version than it is for HZ one. However the difference is small and the overall trend relates to CPU usage quite closely. This is definitely the best match so far. Thanks! Looking at results for 2.6.32.55 branch it seems that we're back at 74f5187ac8 patch - the values are almost the same. The difference between NO_HZ and HZ versions is noticeable. At the risk of sounding like an ungrateful bastard - will there be further attempts at fixing this bug for 2.6.32 kernels?

It seems that load reported by 3.0.28 with and without c308b56b53 patch is almost identical to 3.2.12. This might be more clearly visible on a comparison chart.
