Re: 2.5.65-mm2

I'm getting quite a lot of audio skips with this one. 2.5.64-mm8 was the 
last one I tested and it was very good.

2.5.64-mm8 works fine with pretty much any thud load I throw at it, but thud 
3 is enough to cause some skips with 2.5.65-mm2. Thud 5 causes serious 
starvation problems to the whole desktop.

Please test 2.5.65 base.

doing normal desktop things (gnome, jboss, mozilla, apt-get updates,
etc) i've noticed audio skips on occassion that i had not seen in
kernels previous to 2.5.65.

i'm not going to complain though, because mozilla seems to start
quicker, and my jboss start time has dropped from 1m:10s average to
40s.  very cool!

I've also been seeing this with 2.5.65. 2.5.64 was OK. madplay on .65
skips whilst running wine, mozilla, kde and a couple of gcc's. No
massive drop outs though.

My crude hack helped with thud and some others, but is b0rken for others.

Yay! Still working Radeon :)

And 4x AGP:

Come to think of it, I'll give it a spin, this might be due to a
working DSDT table that was compiled in with ACPI, whereas I had the

I am seeing a significant degradation of interactivity under load with
recent -mm kernels.  The load is dbench on a reiserfs file system with
increasing numbers of clients.  The test machine is single PIII, IDE,
256MB memory, all kernels PREEMPT.

Specifying elevator=deadline improved the response of 2.5.65-mm2
somewhat, but it still eventually became intolerably slow with
sufficient load.

Interactivity tests consisted of switching between desktops with two
instances of Mozilla 1.3 on separate desktops, and Evolution 1.2.2 on
another desktop.  Additional tests included shaking the window and
wiggling the scrollbar.

The third and fourth columns list the number of dbench clients at which
interactivity becomes poor, or intolerable, defined here as getting a
response after:

good		less than 1 second
poor		seconds
intolerable	tens of seconds

kernel			interactivity under load (dbench clients)
			good	poor 	intolerable

2.5.65-bk		 56*
2.5.65-mm1		 <8	16	24
2.5.65-mm2		 <8	16	24
2.5.65-mm2 deadline	 <8	20	28

*2.5.65-bk was still performing very well at dbench 56.  I'll continue
to test up to 128 clients.

2.5.65-bk was updated with a bk pull this morning.

(This email brought to you while running dbench 128 on ext3)

There's a pretty big reiserfs patch in -mm.  Are you able to whip up
an ext2 partition and see if that displays the same problem?

I repeated the test on an ext3 partition, and the response with 28
dbench clients running is definitely better, although I'm starting to
get some stalls of a couple seconds while typing this in Evolution on
the machine under test.  Now it's becoming intolerable, so I aborted the
dbench run so I could finish this email.

This was with 2.5.65-mm2 and elevator=as.  I'll repeat soon with
elevator=deadline.  I didn't try typing in Evolution with 2.5.65-bk
under high loads, so I'll also give that a try.

Summary: using ext3, the simple window shake and scrollbar wiggle tests
were much improved, but really using Evolution left much to be desired.

Replying to myself for a followup,

I repeated the tests with 2.5.65-mm2 elevator=deadline and the situation
was similar to elevator=as.  Running dbench on ext3, the response to
desktop switches and window wiggles was improved over running dbench on
reiserfs, but typing in Evolution was subject to long delays with dbench
clients greater than 16.

I rebooted with 2.5.65-bk and ran dbench on ext3 again.  Everything was
going smoothly, excellent interactivity, and then with dbench 28, the
system froze.  No response to pings, no response to alt-sysrq-b (after
alt-sysrq-s).  A hard reset was required.  Nothing interesting logged.
Too bad.  Before it crashed, 2.5.65-bk was responding to typing in an
Evolution new message window better than -mm2.

I'll see if this is repeatable.

Just out of curiosity, what is the result of:

cat /proc/sys/sched/max_timeslice?

Does setting that to e.g. 50 make -mm2 smooth?

[root@spc1 steven]# cat /proc/sys/sched/max_timeslice
200
[root@spc1 steven]# echo 50 >/proc/sys/sched/max_timeslice
[root@spc1 steven]# cat /proc/sys/sched/max_timeslice
50

Ouch. I inserted the above text saved as a file, and had to wait
over a minute after hitting the OK button.  I aborted dbench which was
running 24 clients on ext3 just to finish this.

The change in max_timeslice didn't seem to improve things.

Apart from the little matter of crashing, 2.5-bk was more usable at that
and higher loads.

I'll try the different value of max_timeslice with dbench on reiserfs
next.  That's where the lack of response was most evident.

I am curious as to whether reverting sched-D4 fixes this.

If not, the first step is seeing whether this is a bad decision made by
the interactivity estimator.  Something like:

	ps -eo pid,nice,priority,command

for dbench, evolution, and X might be useful.

Thanks,

In the meantime, Andrew has asked me to revert the sched-D3 patch.  I'm
recompiling now, and will only have time for that test before I have to
go do other things.

I think I know what he'll see... elevated priority tasks doing round 
robin.  Watch with top d1 showing only runnable tasks and you can see the 
starvation.

The problem as I see it is that when you have a number of tasks which 
become elevated to interactive status, they'll round robin and starve 
non-interactive tasks basically forever.  This is also why my make -j30 
bzImage introduces concurrency problems.  Despite gcc being a cpu hog, when 
enough of them are running, those which have to wait for more time than 
they consume via cpu usage eventually achieve elevated status and round 
robin until they exit... throttling concurrency.  Limiting the amount of 
boost that a task can gain via one activation helps this problem 
considerably, but does not eliminate it.

(think what happens to EXPIRED_STARVING when you have 30 hogs running, a 
few of them doing round robin, and the rest of them just _waiting_ for that 
queue switch to happen.  :-/  ATM, I'm also gathering sleep time at 
schedule time [friendly tasks gain], so sleep_avg will never be consumed if 
you have more than one hog running.  I made the starvation problem better 
for some loads, but utterly deadly for others.)

Something I'm going to try today (yesterday was educational if not 
wonderfully fruitful) is to limit the amount of time a piggy task can 
remain active in the hope of reducing the time interactive hogs can starve 
their expired brethren.  I'm currently thinking forced expire after some 
number of switches * cpu_usage is reached might cure the starvation without 
destroying sleep_avg.

Suggestions very welcome.  (fun problem:)

hmm, I'd always made this sort of change
under somewhat quiescent conditions  -

Interesting results though - it helped on my
system in terms of desktop smoothness, i.e.
visible stuttering of xterm motion when being
dragged around the desktop during dbench -

OK, final question before I get off my butt and find a way to reproduce this:

Does reverting

Sorry, didn't have much time for a lot of testing, but no miracles
occurred.  With 5 minutes of testing 2.5.65-mm2 and dbench 24 on ext3
and that patch reverted (first hunk had to be manually fixed), I don't
see any improvement.  Still the same long long delays in trying to use
Evolution.

Steven,

Do things improve with the patch below applied?  You have to backout the 
schedule-tuneables patch before appling it.

I take it this is the one to back out?

I'll give it a shot when I get the chance.  Unfortunately, I'm bogged
down with meetings tomorrow morning, so it will be at least 14-15 hours
from now.  Perhaps some other adventurous person can pick up the ball in
the meantime.

My test system is 933Mhz PIII, IDE, 256MB. The apps are Mozilla 1.3 and
Evolution 1.2.2 running under KDE 3.1.

[patch snipped]

I tried that patch, and the bad behavior with the Evolution "Compose a
Message" window remains.  With a load of dbench 12, I had stalls of many
seconds before I could type something.  Also, here is an additional
symptom.  If I move the Evolution "Compose" window around rapidly, it
leaves a smear of itself on the screen under itself.  With all -mm2
variants, this smear stays for an intolerably long time (tens of
seconds) while that window does not record keyboard strokes.  2.5.65-bk
on the other hand exhibits much more benign behavior.  Under similar
load, the smear disappears in a few seconds and the window starts
responding to keyboard events.  I just now rebooted 2.5-bk to verify,
and it is still responsive at dbench client loads which would make
Evolution unusable with 2.5.65-mm2.  Mozilla, on the other hand, still
works OK under load with -mm2.  This was all with dbench running on
ext3.

I won't be able to do any more testing for several hours, so have fun!

This is a side effect of Ingo's (nice!) latency change methinks.  When you 
have several cpu hogs running (dbench), and they are cleaning your cpu's 
clock by using their full bandwidth to attain maximum throughput, and they 
then break up their timeslice in order to provide you with more 
responsiveness, and then their _cumulative_  sleep time between (round 
robin!) cpu hard burns is added to their sleep_avg, (boy is this a long 
sentence) you will (likely) find that they run at a highly elevated 
priority and starve the devil out of everything else because they can not 
possibly get enough cpu to eat the sleep_avg they have been given (only way 
to reduce their priority without forking).  Virgin .65 is also subject to 
the positive feedback loop (irman's process load is worst case methinks, 
and rounding down only ~hides it).

I have a really horrid looking sched.c right now that works around some of 
this problem in disgusting ways.  If you want to try it, give me a holler 
before tomorrow morning (slice 'n dice resumes) and I'll rip it out and 
send it to you.  Fair warning though, if you have good taste, don't look at 
it at all before applying.  There are a few of spots I wouldn't even want 
to _try_ to justify.  I don't think dbench will be able to dork it up, but 
irman's process load (horrible thing) now can again.  (it's pure 
research... that says a lot;)

Bottom line is that once cpu hogs are falsely determined to be sleepers, 
positive feedback kills you.

Sure, either post a patch against a known sync point, .65, .65-bk, or
65-mm2, or send me the sched.c file itself (2600 lines might be a little
too much for the entire list).

If you send it in the next 2 hours, I can test today, otherwise I'll do
it mañana.

actually, the round-robining for finer-grained timeslices should not
impact the sleep average at all, because the roundrobin is done while the
task is still _running_, ie. the sleep average does not get impacted.
Otherwise we'd have elevated priority of simple CPU-intensive
applications, which would be Bad.

The way the sleep-average is maintained is balanced very carefully in the
O(1) scheduler. There are three states a task can be in:

 - sleeping: the sleep average increases
 - running but not executing: the sleep average stagnates
 - executing on a CPU: the sleep average decreases

ie. in the roundrobin case the tasks will neither increase, nor decrease
their sleep average - they are in essence 'frozen'. The moment they get
scheduled on a CPU for execution, their sleep average starts to decrease
again. (and once they go to sleep, their sleep average increases.)

so whatever effect you are seeing, it must be something else.

there's no positive feedback loop. What might happen is that in 2.5.65 we
now distribute the bonus timeslices more widely (the backboost thing), so
certain workloads might be rated more interactive. But we never give away
timeslices that were not earned the hard way (ie. via actual sleeping).

i've attached a patch that temporarily turns off the back-boost - does
that have any measurable impact? [please apply this to -mm1, i do think
the timeslice-granularity change in -mm1 (-D3) is something we really
want.]

(backboost alone is not it, nor is it timeslice granularity alone... bleh)

I still don't have anything worth discussing.

(however, I have been fiddling with the dang thing rather frenetically;)

Yes, this makes a difference.  (everything in sched makes a 
difference)  The basic problem I'm seeing is load detection, and recovery 
from erroneous detection.  When it goes wrong, recovery isn't happening 
here.  cc1 should not ever be called anything but a cpu hog, but I've see 
it and others running at prio 16 (deadly).  This is nice if you're doing 
deadline scheduling, and boost cc1 because it's late, ie intentionally, to 
boost it's throughput.  What I believe happens is that various cpu hogs get 
miss-identified, and get boost with no way other than to fork 
(parent_penalty [100%atm]) or use more cpu than exists. (I think)  This I 
call positive feedback.  The irman process loop is really ugly, and the 
scheduler totally fails to deal with it.  Disabling forward boost actually 
does serious harm to this load.  The best thing you can do for this load 
with the scheduler is to run it at nice 19.  You can get a worst case 
latency of 50ms without much if any tinkering.  (no stockish kernel does 
better than 600ms _ever_ on an otherwise totally idle 500Mhz box 
here.  ~200ms worst case is the _best_ I've gotten by playing with this and 
that priority wise)

There may be something really simple behind the concurrency problems I see 
here.  (bottom line for me is the concurrency problem... I want to 
understand it.  The rest is less than the crux of the biscuit.

(generally, concurrency is much improved, and believe it or not, that's 
exactly what is bugging me so.  Too much is too little is too much.  I'm 
not ready to give up yet.
