The GPU Folding Thread... X1900 owners in here.

Right, ive got it working 100% but it gets an eue after 4-5 points, im quitting the gpu part and back onto dual core until the service bit is fixed and the gpu client is more stable.

Still, thats a damm good start and it seems to work well.

I hope to see more cards supported (perhaps the whole x1k range?)
 
Just hit Step 7 and all is well so far. 50% of my CPU is still going to the GPU client. However, I have just read on stanford that although it may show a high CPU usage in actual fact it isn't using that much. So if that's true it looks like maybe there is a quirk in how Windows measures CPU activity.

Tries it and sacked it as I do not want to use those crappy 6.1 drivers. Worked straight away as a service didn't have to do anything but follow the instructions, however, game play with those drivers is rubbish, so bye bye until they get a better driver sorted.

Been on Far Cry once or twice with the 6.10s and no problems. The 6.5 drivers also work with the GPU client according to Stanford, not worth trying those? The 6.5s were very good I believe. At least in my experience.

Apparantly the project my X1900 is crunching [2711] is worth 220 points! Judging from the last 10 steps [and assuming its 10 of 100 steps] then this WU is gonna take another 12 hours or so. That's a PPD of 440!

Not bad :D

Yes, noticed that earlier so went back to the 6.5s which are much better. I have dld the GUI version (sans fancy graphics) set cpu to 95% and its happily crunching away. I prefer this client for the mo because its so easy to switch on and off. Will leave it on tonight and see how this has affected my dual cores and post a log tomorrow.
 
Anyone had any luck getting it to work on vista. A heads up would be useful before I start messing around.

My guess is that the DX 9.0c is going to be the problem.

Shame to let this X1950XTX sit idle. :(

Officially it only works with XP and I suspect that Vista's new driver model will be the problem beore DX9.0c has a chance to muck it up. However, I'd love to be proven wrong. :D
 
Oh darn. I've had 3 EUEs overnight :(

According to your link rich there is an issue with the 6.10 drivers - might explain why ATiTool wouldn't work properly for me yesterday.

Will turn off client for now and roll back to 6.5s later on today and try again.

EDIT: I have also noticed quite a large impact on my CPU output. A 600 pointer took nearly 2 hours to complete a frame. As such the ETA is 3 days rather than the usual 1.5-2 days it normally takes.

Be great if someone can crank back their CPU utilisation and see if there are any improvements - rich's link says about 95%.

Assuming the PPD of the GPU is as high as I worked out it is only just worth running. But having said that is using my GPU 24/7 increasing temps and sucking more juice worth losing effectively 50% of my CPU. With the current run of WUs I get 600PPD, with the GPU client I am looking at about 700PPD. Not really a massive boost given the amount of effort lol.

Just a quick question.
You guys have mentioned the CPU usage being at 50-100% which it probably isnt according to Stanford.
I was wondering if the GPU client is using system ram or is it just using the graphics memory?

PPD seems not as high as I was expecting when you consider QMD units would complete in 20 hrs or less on a fast P4.

Its great to see it does work and its great to see you guys trying it and logging your results and "do,s and dont,s". Nice work guys. :)
 
I'd say this isn't stable enough for mass adoption and a pimping thread, so that'll have to go on hold i think.

Seems like they are making good progress on the bug fixing over at stanford thanks to concorde and others, so thats good.

My only issue is the poor ppd, in most cases it seems its better to leave the gpu client off and fold on the cpu core that it would otherwise rob, which is a shame considering the amount of effort required to get the thing working in the first place. Hopefully they will increase the points and make it more worthwhile.
 
I have had the client running all night, a couple of switch offs this morning by me, the GPU client has had no probs whatsoever. Have now completed 65 units. What I have noticed is that the client is using around 150 MB of ram, CPU utilization is at 50%, with the other 50% being split by the cpu's.

According to the cpu logs, production times have doubled, which matches data from task manager. In other words, task manager is right, the gpu client is robbing 50% of cpu output, thus doubling cpu client completion times.

For the loss of ppd it is not worth running the gpu client. I will stop using it when it has finished its current WU.
 
So is there a proven formula to get it working it does it require individual tweaking in every case?

So if they raise the points and fix a few of these issues its all good. The points is the really annoying thing, we were promised big points.
 
There needs to be some incentive to use the GPU client (apart from the benefits to the science). If people are going to lose points, they will be less likely to use their GPUs for Folding which would be a terrible waste of resources.

it's a bit of a tricky one. On the one hand, if you don't offer enough points to make it worthwhile running the client, people won't run it. On the other hand, if you offer too many points, you will alienate those who cannot participate and some may discontinue folding on their CPUs as they cannot compete with the GPUs.

A fine balance needs to be found.
