Lets get some gpu folding done

[angra]

I think it'll be awhile before anyone catches up with you angra (if that is even possible!)

I don't mind if people catch up to me . But other teams that are less reliant on a server farm may close the gap and/or outgain us. On the other hand, XS is probably more likely than the average F@H team to have a lot of GPUs, so who knows.

[sc00p]

People! You has to remember this a beta testing phase... there will be adjustments after this. I found that link that Pythagoras gave to official forums is very worthfull But Sparky found himself some of the tweaks they did.

And. If this (gpu folding) means I'm at team stats 100th in future... it's perfectly fine by me if it means our team performance leaps compared to the other teams. Or what do think Angra. Wouldn't that be great :P We will still always remember and cherish your efforts !
EDIT: you answered to this while I was writing. I'm glad you think that way

[angra]

I wanted to mention one thing that I have noticed doing GPGPU research. (of which FAH-GPU is a subset of the field).

I have found that for doing real calculations, the GPU is _way_ more sensitive to overclocking than for playing games. To the point that when I am doing research work, I never ever overclock my GPU, only run it at stock. This may be overkill, but if you guys start having any problems, I would definitely suggest going to stock speeds as an early step, even if you feel like you are 100% stable for games at higher settings.

Glory is nothing! The team is all!

I want XS to excel. The individual points are nice, but if I had a magic wand to make the rest of XS 1000x more productive at a snap and leave me the same I would do it in a heartbeat

[Bloody_Sorcerer]

angra, how does it compare to ATITool's "artifact detection" system? Perhaps that is GPGPU-based for a good load...

well, my x1900GT is on board

QFT You're the man

And our talks don't really have yet anything to base on... as you've got quite a bunch of points LOL
One would need lots of gpus at full efficiency if wishes to overtake you

EDIT: I need to go to sleep... it's 2:30 AM here Carry on.

Well from reading on stanford's F@H forum I need an X2 if I want to run the GPU client and one CPU client at the same time. Sounds like that might change later, but at this point that is what is needed. I have a little over 4 hours left on one WU that my CPU is doing so once that is done I think I'll kill the CPU client and run the GPU client instead for a while and see what happens

Maybe I'll mess around with priorities later on and see if I can get the CPU client and GPU client running at the same time without sacrificing too much of either.

my FAHCore_10.exe doesn't seem to be using very much CPU power... its used 30 CPU-seconds in the past 20ish minutes. but, then again, it hasn't completed one step yet even and GPU temps are low (49C according to ATITool )

i don't know, sorry. my experience and comments are anecdotal at best and not rigorously studied

[Bloody_Sorcerer]

ok
im keeping mine stock regardless... heck, on the stock cooler, i wouldn't even OC it for games.

If you have your CPU busy with other F@H clients it will not. Right now you need a whole core to work in conjuction with the graphics card. If I am understanding it correctly they are hoping to make it not that way later on but at this point that is how it is.

[Bloody_Sorcerer]

I've got priority for FahCore_10.exe and FAH505beta1-console.exe both set to "normal", so it can steal all the CPU cycles it wants. It is doing something though, it just completed its first step

Catalyst driver version 6.5 [download from ATI or from a Stanford mirror ]. Version 6.10currently does NOT work [download from ATI ] and ATI is working to fix this. Versions 6.6 and 6.7 will work, but at a major performance hit; 6.8 and 6.9 will not work at all. Due to all the complexities of support, we will support only versions 6.5 and 6.10.

Just to add some info

[Sparky]

Wait, 6.10 does not work now? Darn I gotta downgrade my drivers then to 6.5 I take it. hmm.....

[cadaveca]

6.10 works here.

[Bloody_Sorcerer]

thankfully ATI driver downgrades are waaay easier than nvidian ones

very true, I just wish I knew about that before I upgraded to 6.10

[Sparky]

Same here. When I upgraded stanford's site still said 6.5 or 6.10. Ahhh figures

[freecableguy]

6.10 drivers, 5.0.5 F@H GPU console client...CPU runs ~55% and the GPU temps on my X1900XTX @ 685/800 tops out at around 87C with silent aircooling....may need to hold off on this until I get these cards back under water...never seen GPU temps that high before! wowzers.

[Sparky]

heh that is normal operating temps

I'm serious, I have the stock cooler on my stock X1900XT at stock settings and see 90*C under load consistently. Nothing abnormal there.
I don't necessarily like it though but not much I can do. I can't afford watercooling and these 3rd-party coolers don't seem that great, although the new thermalright looks promising. I really want the IceQ3 cooler that HIS has but I can't get one separately.

This'll drop alot of people's GPU overclock...

[xlink]

umm... new GPU stability test?

Most likely

[Sparky]

OK I got it running, so far it has done 3 steps (or whatever they are) and the GPU temps are staying around 73*C (stock everything except for some AS5 in place of the original stuff). Taking just over 8 min per step. I have it set to request 100% usage, idle priority. I have had one EUE so far.

Interesting thing is, it is working my CPU harder than the CPU F@H client does My CPU fan is set to ramp up at 47*C and typically the temps while running the CPU client are around 45-ish so I rarely hear the fan kick into high gear. However right now I am hearing the fan speed up/down, up... down, up....down, etc. Interesting. Also the memory usage is very high - currently it is using about 160MB of RAM and 160MB of pagefile.

I'm guessing it'll get better and less of a system hog as they refine it.

[hoax]

is it possible to run 3 instances on a dual core p4 with a x1900xtx? one instance on each core like I have now and an extra one on the gpu?

or do I have to turn off the cpu instances to run the gpu version?

thanks
