This version contains minor bug fixes and improvements to the zaphod
scheduler including changes to the default configuration parameters that
take into account the results of tests using Con Kolivas's new (and very
useful) interbench benchmark tool.
A patch from Plugsched-5.2.3 to PlugSched-5.2.4 for 2.6.12 is available at:
<http://prdownloads.sourceforge.net/cpuse/plugsched-5.2.3-to-5.2.4-for-2.6.12.patch?download>
and a full patch for 2.6.13-rc6 is available at:
<http://prdownloads.sourceforge.net/cpuse/plugsched-5.2.4-for-2.6.13-rc6.patch?download>
Very Brief Documentation:
You can select a default scheduler at kernel build time. If you wish to
boot with a scheduler other than the default it can be selected at boot
time by adding:
cpusched=<scheduler>
to the boot command line where <scheduler> is one of: ingosched,
nicksched, staircase, spa_no_frills or zaphod. If you don't change the
default when you build the kernel the default scheduler will be
ingosched (which is the normal scheduler).
The scheduler in force on a running system can be determined by the
contents of:
/proc/scheduler
Control parameters for the scheduler can be read/set via files in:
/sys/cpusched/<scheduler>/

In next parts:
- time make all -j64
- time make all -j512 (it maybe very high load ;))
- interbench-0.29 tests
Suggestions, criticism are welcome.

where the (x,y) after zaphod means (max_ia_bonus, max_tpt_bonus) and "d"
means default. I had to kill a few significant digits to squeeze it
into 71 columns. Overall statistics are extracted from the schedstats
data. In the "Build Statistics" "CPU" is the sum of the user and sys
times and "SYS" is the percentage of that which was sys time (as I feel
that is a better thing to compare than raw sys times).
I was intrigued by the fact that zaphod(d,d) and zaphod(d,0) take longer
in real time but use less cpu. I was assuming that this meant that some
other job was getting some cpu but the schedstats data doesn't support
that. Also it wouldn't make sense anyway as you'd expect jobs doing the
same amount of work to use roughly the same amount of cpu. My latest
theory is that your machine has hyper threads and this artifact is
caused by the mechanism in the scheduler for handling tasks with
differing priority in sibling hyper thread channels. Does your system
have hyper threads?

That would only do something if there was a difference in 'nice' levels. What
you're seeing is the fact that balancing is intimately tied in with timeslice
size and you have increased idle time.

No that's not what I was saying at all. I know you're planning on trying
interbench. What I meant was you should enable "compute" mode for these
kernel compile based benchmarks.
In a plugsched based kernel look in:
/sys/cpusched/staircase/
and set compute to 1

Very nice thank you.
Since you are benchmarking, here is an unofficial update to the staircase
patch to the current non-plugsched version which will affect the results of
interbench (it won't change the benchmark results of compute mode).
Cheers,
Con

Not in zaphod and spa_no_frills. They user dynamic priority. I may
rethink this as the argument for using dynamic priority mainly applies
to the entitlement based mode of zaphod.

I partially agree in that reducing the time slice size would reduce the
size of the effect but it's not the cause of the effect. The hyper
threading code is the cause.
BTW I'm wondering why the TPT column (i.e. cpu time / real elapsed
time) is so low for all schedulers. It's been a long time since I ran
your "contest" benchmarks for any of these schedulers but I seem to
recall that they all did a lot better than this when I extracted the
equivalent data from the output. Generally, I think that they all used
greater than 95% of the available cpu time which would be the equivalent
of TPT values of 190% or more in this case.
Another interesting thing to be noted in these numbers is that the cost
of the extra context switches caused by the "improved interactive
performance" measures doesn't seem to be very significant.
It also looks as if the overhead for zaphod's IA bonus mechanism needs
to be reduced.

Static - like mainline and staircase - would be a good idea as the whole point
of hyperthread-aware 'nice' levels is they obey 'nice', not dynamic priority.

He did a make allyesconfig which is a bit different and probably far too i/o
bound. By the way a single kernel compile is hardly a reproducible benchmark.
Ideally he should be using my 'kernbench' benchmark (hint hint).

I doubt this workload is running into that, the i/o bound nature of a kernel
compile means it is not really a pure cpu usage scalability measure, it's
just easy to do. Check the lkml archives for some comments by WLIrwin on the
limitations of using kernbench as a scalability measure.

No, they're different things. Kernbench is a script to do the kernbench
measurement as used by M. Bligh. It's one of my family of benchmarks ;)

Yes, but when zaphod's in "entitlement based" mode dynamic priority is a
better measure of "nice". But I think I'll modify spa_no_frills and
zaphod in "priority based" mode to use static priority (as you suggest).

I should have calculated the average cpu consumption per context switch.
If that's reasonably large then the number of context switches won't
matter much. It's probably more a interesting number than the count of
context switches so I'll alter the script accordingly.
I would have liked to have done more analysis of the load balancing but
some of the schedstats data was corrupt. It should be roughly the same
for all schedulers if my attempts to make scheduling and load balancing
orthogonal have been successful. I was thinking of doing something
equivalent to a Chi-squared test to get a single number that describes
how good load balancing has been.

The X test under simulated "Compile" load looks most interesting.
Most of the schedulers do quite poorly on this test - only Zaphod with
default max_ia_bonus and max_tpt_bonus manages to deliver under 100ms
max latency. As expected with interactivity bonus disabled it performs
horribly.
I'd like to see some results with X reniced to -10. Despite what the
2.6 release notes say, this still seems to make a difference.

The compile load is not a real compile load; it is an extreme exaggeration of
what happens during a compile and this is done to increase the sensitivity of
this test. It is _not_ worth trying to get a perfect score in this.

Well of course it helps X - but then any X load totally fscks up audio on
mainline and staircase which is why it's recommended not to renice it.

Even spa_no_frills, which does absolutely nothing to help interactive
(or other special interest) tasks, can cope in these circumstances as
illustrated by these results from my (relatively old) SMP machine show:
--- Benchmarking simulated cpu of X nice -10 in the presence of
simulated ---
Load Latency +/- SD (ms) Max Latency % Desired CPU % Deadlines Met
None 0.01 +/- 0.129 2 100 99.3
Video 0.007 +/- 0.0818 1 100 99.3
Burn 0.006 +/- 0.0817 1 100 99.3
Write 0.033 +/- 0.271 3 99.3 98
Read 0.046 +/- 0.337 3 98.4 97
Compile 0.023 +/- 0.208 2 99.3 98.3
Memload 0.043 +/- 0.31 3 98.1 97
This machine isn't directly comparable with Michal's so for comparison
here are the results from "out of the box" Zaphod on the same machine:
--- Benchmarking simulated cpu of X in the presence of simulated ---
Load Latency +/- SD (ms) Max Latency % Desired CPU % Deadlines Met
None 0.02 +/- 0.2 2 99.3 98.7
Video 0.007 +/- 0.0818 1 100 99.3
Burn 0.023 +/- 0.208 2 99.3 98.3
Write 0.147 +/- 0.949 12 94.7 93.2
Read 0.033 +/- 0.258 2 98.7 97.7
Compile 2.94 +/- 10.7 105 76.8 71.6
Memload 0.017 +/- 0.153 2 100 98.7
As you can see there's evidence in these numbers the file writes are
implicated in the bad numbers for the Compile load (which is a mixture
of Burn, Read, Write and (I think) Memload). So testing with different
I/O schedulers might be interesting.

I don't see the point. X works fine as is without renicing not withstanding
these extreme loads in interbench. Furthermore, reworking of xorg code to not
spin the cpu unnecessarily when the gpu is busy is underway and tuning the
cpu scheduler unfairly for an X server that will no longer behave so badly is
inappropriate.

Maybe we could use interbench to find a nice value for X that doesn't
destroy Audio and Video? The results that I just posted for
spa_no_frills with X reniced to -10 suggest that the other schedulers
could cope with something closer to zero.

See, that's where we disagree, I certainly don't believe X "works fine".
Compared to MacOS and (especially) Windows the Linux desktop is WAY
sluggish.
For example when I cycle through windows with alt-tab in X, it can take
5-10 seconds for each to render. I can see the application's widgets
being drawn one at a time, then finally the border. Repeated
alt-tabbing between the same two windows seems to cause a CPU intensive
redraw of the entire window. It's as if X just discards the rendered
contents of a window as soon as it's obscured.
On Windows this works as expected - cycling through windows whose
contents have already been rendered is *instantaneous*.
I agree that tweaking the scheduler is probably pointless, as long as X
is burning gazillions of CPU cycles redrawing things that don't need to
be redrawn.
Then again even the OSX scheduler has hooks for the GUI. Presumably
they concluded that the desktop responsiveness problem could not be
adequately solved within the framework of a general purpose UNIX
scheduler.

It's an X problem and it's being fixed. Get over it, we're not tuning the
scheduler for a broken app.

I wasn't saying it would be a smart thing to do, the OSX thing is
interesting that's all. I think we're in violent agreement about the X
problem, do you have a link to any specific work on this (off list)?

You're right, this problem seems much, much better in Xorg 6.8.2. I
think the Damage extension might be responsible. There's definitely
something different happening because when I switch windows quickly,
instead of a grey box that gets slowly re-packed with widgets, I see a
black box that packs very fast, and seems to be filled in large
rectangular chunks rather than one widget at a time. X is also using a
lot less CPU. Very nice work...

Was there any reason you chose 128? Optimal usually works out automatically
from kernbench to 4x number_cpus. If I recall correctly you have 4 cpus? Not
sure what 128 represents.

No, I just have 1 pentium 4 with ht ;).
Why I chose 128? I just want very high loads. Now I'll try -j192 and
-j256, but I don't know how does my system survive it.

Well it will survive all right, but eventually get into swap thrash territory
and that's not a meaningful cpu scheduler benchmark.

Ok. How about make -j? It's one of kernbench test runs, on my box load
average > 1500 ;).
BTW I have only 1 gb ram, so high values of -j are road to hell for my system...
I'm still learning, but it's fun ;). Now I'll try your latest -ck.
Thanks for "1Gb Low Memory Support".
