GPU2 CPU usage?

oceaness · 22 Jul 2008 at 21:34

The GPU2 client shouldn't need a whole core from my E6600 should it :confused:

Task manager is showing fahcore11.exe using 50% i.e. a whole core.

verbal · 22 Jul 2008 at 21:52

It uses 39% of my Athlon 64 3200 @ 2000mhz in Vista 32bit. Other people say it uses only 5% or so of one core.

Well my 8800 GTS only uses 3% of my Q9450, but the 9800 GTX wants 50% of my E6600.

I know those GPU's are round the wrong way but I only have the 9800 GTX temporarily, and it was the easiest machine to get it crunching in quickly. Also the E6600 rig is 24/7.

It seems to be working ok (fahmon just shows it as *hung* even though it's checkpointing fine) I just can't really run the SMP client as well.

You can tick the box marked "ignore asynchronous clock" in the monitoring section of options in FahMon to get rid of the *hung* message

8800GS uses a whole core of my Q6600.

Cheers for that all my clients keep going red and the PPD dissappearing, been bugging the hell outta me lol.

And wierd how some people have to give a whole core and others only a few %

I mean surely 1 core of the E6600 cant be that much slower than 1 core of the Q9450. I mean we're talking 2.4GHz vs 2.66GHz but an increase of 47%.
Although at 50% it's basically hitting the roof of the processor.

Oddly the CPU temperature does not increase by even 1°C so the CPU isn't actually doing anything :confused:

I will leave it overnight and make sure it's settled then run a little experiment and report back

My 8800GT uses about 5-8% - so about 20-25% of one core. However I do have to use an external program to keep the windows priority of the GPU client above the VMWare priority in order for the usage to be maximised.

Are you on XP?

So far I have noticed:

My 8800GTS is on Vista and is uses 3% of a Q9450
My 9800GTX is on XP and is using 50% of an E6600.

Verbals is on Vista and is using 39% (high because it's an old single core processor)

If you are on XP and your 8800 GS is using a whole core that could be the problem and there could finally be a good reason to switch to Vista

Yeggstry Vista or XP?

theheyes · 22 Jul 2008 at 23:19

I think hes on Vista, could be wrong though.

If you're sure you're getting weird CPU usage probably best report it on the official forum with it being beta et al.

oceaness · 22 Jul 2008 at 23:37

Yes I will report any findings on the official forum, but I want to get a little more info

Yeah the 8800GS is in a x64 XP rig. The card won't work with the motherboard in my Vista Q9450 rig, so I haven't had the chance to see how much CPU it uses in it. I'll maybe have another go at trying to get it running tomorrow.

Mattus · 23 Jul 2008 at 02:11

I'm on Vista x64 - 8800GT uses 3-4% of my Q6600, so 12-16% of one core. It definitely has something to do with the OS, though IIRC Yeggstry is on XP, so his results don't seem to fit the pattern :confused:

Yeggstry · 23 Jul 2008 at 07:15

Yes I am on XP. I'll update my sig

I'm not sure what I'm doing differently, but if I figure it out I'll let you know

Always one isn't there :rolleyes:

We need more GPU folders

From the folding forum:

toTOW said:
We still don't know exactly why XP always shows 100% ... maybe an overload related to the way driver/kernel communication works in XP. Keep in mind that Vista introduced a new driver model.

Seems like they are aware of the problem.

Yeggstry they might be interested in your setup as I think your probably the only person running XP whose not sacrificing a whole core to the GPU client?

Yeggstry · 23 Jul 2008 at 09:40

You can point me to where that is please?

booyaka · 23 Jul 2008 at 09:47

i'm similar - running xp and also a full core is dedecated to the gpu folding as well - it does drop some times to around 8-10% useage but most of the time it's up around the 20-25% cpu useage with my quad on xp

LMAO, sorry, cant believe I forgot to include the link :rolleyes:

The thread where I read the post by toTOW is here
The last post was on the 11th July though.

I wonder how your setup is different to everyone elses :confused:

Perhaps something to do with your priority prgram.

Cob · 23 Jul 2008 at 17:35

Dunno why but my GPU client is using much less CPU time today. It's PPD has fallen by about 150, by the 4 linuxSMP clients have gained about 150ppd each.
