Core appointment lock to 100% CPU

[GerardA]

Hi Peter,

Just found out why my tvviewer doesnot decode the satelitechannels properly on my htpc.
2 cores are at constant 100% CPU. And I did not even use XXHE after I turned on the PC.
So I started XXHE to see what happens.
Core appointmant was 3-5 (?) and when I changed it to 'no appointment' I saw the  CPU on core 0 and 1 go to zero and after the music started to play all 4 cores went up to 100% CPU and stayed there.
Is there a way to get my CPU back to normal?

Hey Gerard,

It seems that you suggest that this 100% (with your TV vieuwer) is caused by XXHighEnd. But are you ?

So just this question first.

Hi Peter,

Yes, that's what I think.
In the resource manager I checked the performance because the tv-program was not behaving like it should and I saw two cores constantly at 100% cpu.
After that I started XXHE (for the first time after starting the PC)
and changed core appointment to 'No appointment' and started the music. Now the two cores first went directly to zero % and quickly after all 4 cores went up to 100%. Music played perfectly...

Maybe the solution is to play some music with Q5 <> 1 before ending XXHE.
BTW, after playing the music CPU went lower on 2 cores, and I stopped XXHE3 with the blue led to the right and this made the cores go up to  100% again.
Maybe for AMD 4-core things go different from  Intel?
Today I will try some more...

[PeterSt]

Gerard, in the situation that you have this 100% (say right after a reboot), what processes are consuming cpu (say for more than a few % only) ? Just look through TaskManager.

Is this in Normal OS Mode ? if so, is this also in Minimized OS Mode ?

Regads,
Peter

[GerardA]

That's the problem, I don't see which processes are using the CPU.
It's unattended.

[PeterSt]

Sorry that this takes a bit long (for Q&A) but do you mean "nothing consumes" or "changes a lot but many processes do" ?

Or do you mean that you don't know how to observe this ?

[GerardA]

Haha, it's difficult to explain.
I see svshost take the most but total maybe around 10 to 30 percent.
When I play XXHE core 2,3 and 4 go to 100% in the graphic, core 1 about 25%. Core 1 and 2 are mirroring like there are some spikes for 1 to go to 100% for some seconds and then core 2 goes to about 25%.
In the list XXHE takes about 55% of the total, the rest is unexplained. After the music stops core 1 and 2 go to less then 10% but 3 and 4 are wildly going up and down from 0 to 100% averaging about 50% and the system total stays around 30%.
All this is now with appointment 1-3.
I see Service Host Local Sytem and Remote Procedure and Local security Authority Proces (and Resource manager) taking most.

Maybe 30% at rest is normal for Win8.1?
But why all on core 3 and 4 and 1 and 2 sleeping?
(Now and then I see 'parked' at some of the cpu's)

Gerard,

Gerard, in the situation that you have this 100% (say right after a reboot), what processes are consuming cpu (say for more than a few % only) ? Just look through TaskManager.

I don't want XXHighEnd to be involved. So, you nicely explained everything, but while at least you used XXHighEnd and as it seems at first, I can't even tell which of text is explicitly without XXHighEnd involved. Reboot ... and then the outlay again please.

Peter

[GerardA]

OOOOh, this is complicated!

I restarted and CPU was at 2%. Very nice.
I started XXHE and played one song.
CPU1 fluctuating between 75 and 100%,
CPU2 fluctuating between 0 and 25%, totaling (1,2,3,4) 25%.
(CPU 3 and 4 at 0%)

But than... about halfway the 4 minute song Core 3 starts to go up.
all the way to 100 %, then a little lower but core 4 takes over the difference.
After the song core 1,2,3 are about 0 % but core 4 stays at 100%.
Mainly service host processes.

I'll try a restart again...
Ok after restart back to 1% total.
I hope you can make sense out of this?
Now after a few minutes rest I look again and total CPU around 30%. Core 1,2 and 3 working constantly, maybe nothing to do with XXHE?

[PeterSt]

Notice that with XXHighEnd playing, any high cpu usage is normal (core at its own 100% which means for one core only a total of 25% when 4 cores are available), BUT for 2 cores only.

So, something seems to go odd once you start playing (or somewhat later). I have seen this in another occasion and this is intel 8 cores (4 Hyperthreaded). But now right after a reboot and in Normal OS only ... Random processes consume high cpu ...
That situation is not worked out yet and so far I can not dedicate it to XXHighEnd causing it. Still it seems 1.186 related because it started happening when that was installed (used). But when you are a second ...

Peter

[GerardA]

Yes, I guess XXHE is doing something in this direction.
Playing a song again gives 100% cpu for 2 and 3 and 1 and 4 are back to zero.
If it's not the cause then at least the solution (partly that is).
Hope you find out more!
(I just see 1 and 2 mirroring and 3 and 4 mirroring,like 1 going up 10% and 2 going down 10% at the same time)

That is purely XXHighEnd. But it ain't right when you chose a Scheme implying the usage of of 2 cores only. And maybe now I am confused which you use when (to solve what etc.).
Can't you just use 1-2 and look at that ? This should never ever engage core 3 and 4.
Notice that NOW we are talking about XXHighEnd usage, which actually is not your problem. But supposed that XXHighEnd still uses 3 and 4, then something is wrong to begin with (and may lead to (the solution of) your actual problem).

Hope you find out more!

That looks like I am working on something ? Nope. I can't, because I don't have the problem. So it's just you observing things and report about it, and maybe I can make something out of that.

Meanwhile and outside of everything, and now about the normal behaviour of the PC ... when you set Q3,4,5 to 0,0,0 - do you ever see the problem again ? Notice the strangeness as it comes across to me, because while you try to get rid of the problem once it has started (which doesn't seem to be after a reboot without playing), I try to avoid it. Looks the same but is different.

Did you already answer my question about MinOS vs NormOS ?

Peter

[GerardA]

For the last description I used core 1-2 and unattended in normal OS.
Maybe I should never have tried 3-5 appointment because there are only 4 cores?

Setting Q3,4,5 to 0 gives 100% for core 4 and 0% for core 1,2 and 3. After the end of the song killing the Engine sets Core 4 back to 0% but 1,2 and 3 go up to about 30%.

And now restarting but still waiting... (15 min.)
Time for some hard action!

[PeterSt]

Maybe I should never have tried 3-5 appointment because there are only 4 cores?

Hmm ... This is checked for when engaging the Scheme, so if you can just select that, something really is wrong to begin with. And I don't mean XXHighEnd ... (just tested it again on a 4 core machine).

Otherwise I really don't see how even such a thing can remain "persistent" or better : sort of destroys what the OS is doing (or wants to do). Also, at 0,0,0 nothing strange should happen in the first place (just close to 0% cpu usage of Engine3.exe and certainly no high cpu usage elsewhere). I just checked that too. So that's a stable 1% usage with SFS=0.4.

Maybe W8.1 plays a role here, but I never saw anything strange like this; and when I tried it (for a week or so before I gave up on it (SQ)) I'm pretty sure I didn't have any Q5 at 1 (Q3 and Q4 where not operative for their new functins and I had those at 0). So my Q5 will have been at 3 or 5 and that doesn't imply high cpu usage which I also didn't see for W8.1 (and I watch cpu graphs all the time).


And now I still don't know whether the behaviour is different in MinOS. Is this question so difficult ?

Peter

[PeterSt]

Just thinking ... I would set the SFS to 12 or so for minimum, or otherwise *that* is a reason for high cpu usage. I'm referring to normal XXHighEnd observement now (so, for when you are doing that).
