Declining performance - any advice?

It seems that a lot of GPU problems revolve around specific versions of drivers. Though NVidia has their own support structure, you can often learn from information reported by others who fold.

Declining performance - any advice?

Postby Nick200 » Sat Feb 28, 2015 4:29 am


Grateful for any advice people have to offer. The issue is that the overall FAH output of my PCs seems to have fallen considerably despite having upgraded some of the hardware - and followed collective advice as to the best hardware mix and software configurations (thanks to Napoleon].

My systems used to bring in around 600K PPD but now generate only around 350 - 400K PPD total (if I am lucky). The number of WUs completed seems comparable with previous performance. My FAH ID is montague-cripps.

So, my info is as follows:

All my rigs operate under windows 8.1 Pro with media centre, fully patched, running FAH 7.4.4.

I have configured the BIOS where possible to use the iGPU so that the graphics cards are wholly dedicated to folding.

The individual details including FAH logs are as follows:

Rig 1
Intel driver 327.23
Intel Core i7 4790K @ 4.00GHz
3072MB NVIDIA GeForce GTX 780 (ASUStek Computer Inc)
3072MB NVIDIA GeForce GTX 780
FAH PPD estimate 115751

So is there anything I can do to get back to the levels I used to be able to generate? Is waiting for a "fixed" Nvidia driver the only hope, however much that seems to be pie in the sky? Is it down to the mix of cores, WUs and points schemes at the moment - will that change or is it just the new normal?

I am not keen to invest any more in hardware if all that results in is declining performance and less valued science...

There's hope. A potentially "fixed" version of the nVidia driver. It may be a bit before it's rolled out, but progress has been made.

You didn't mention the power saving features in Windows. Please confirm that all your CPUs are configured to avoid sleeping (unless you have a reason to choose otherwise).

From the configurations that you've shown, I see a total of 9 slots. WUs have been returned from more slots than that, but my data counts some older configurations that may have completed WUs and then gone off-line within the last 90 days due to the reinstall of one or more clients.

Please identify a recent WU completed by each slot. Everything seems to be getting QRB except I'm seeing some strange errors from one or more of your GPUs. Please identify a recent WU that was completed successively by each GPU.

What types of changes have you made to your settings within that time period?

Re: Declining performance - any advice?

Thanks for getting back to me.

Other than swapping some hardware around and consequential driver changes, which was completed in early Feb, I have not made any changes. The only other recent change and outage was due to blowing a GTX 780 which was RTMed and replaced. Unfortunately that took out the SLI rig (rig 1) as I had to install some new fans in to stop it overheating as it's summer down here. I am now up and folding with rig 1 - and with much better temperatures now.

I do not enable any power-saving features in Windows. I have switched off any sleep functions as I want the machines to run FAH unattended 24/7.

Yes, 9 slots at present.

    Rig 1: 3 slots: 2 x GPU and 1 CPU: recent WUs: WU03:FS00:0xa4:Project: 9007 (Run 1233, Clone 2, Gen 127); WU00:FS00:0xa4: Project: 9009 (Run 308, Clone 2, Gen 314), WU01:FS01: 0x17:Project: 13000 (Run 1906, Clone 0, Gen 41) and WU03:FS02:0x18:Project: 10488 (Run 3, Clone 4, Gen 15)

    Rig 2: 2 slots (1 x GPU, 1 x CPU): recent WUs: WU02:FS00:0xa4:Project: 9014 (Run 206, Clone 8, Gen 51); WU01:FS02:0x17:Project: 9411 (Run 1174, Clone 0, Gen 1)

    Rig 3: 2 slots (1 x GPU, 1 x CPU): recent WUs: WU02:FS00:Sending unit results: id:02 state:SEND error:NO_ERROR project:9114 run:26 clone:1 gen:7 core:0x18; WU00:FS01:Sending unit results: id:00 state:SEND error:NO_ERROR project:9014 run:252 clone:1 gen:136 core:0xa4 unit:0x000000a5664f2de453e558bd61673e61

    Rig 4: 2 slots (1 x GPU, 1 x CPU): recent WUs: WU04:FS00:0xa4:Project: 9016 (Run 285, Clone 7, Gen 87) and the GPU seems to be having trouble with some Bad Units at the moment:

I tried posting the full logs from all 4 rigs but as they have been on constantly for weeks the post exceeded the character limit. So I deleted everything but the headers. Let me know if you want the full log details for any of the rigs.

Other slots may occasionally produce WUs but they are laptop based, and I don't monitor them.

I think you might also have seen some WUs from a failed experiment of mine: I tried installing an old GT9880 and a GT250 in spare PCIe-16 slots on top of what was in the main slots - but I could not get FAH 7.4.4 and the FAH 6.2 GPU2 console to co-exist. There were too many driver clashes, crahses and confusions. So that stopped and with it any extra WUs.

As for the future, I will wait for the promised Nvidia driver that sorts out all these performance issues. I run 347.52 for the GTX 980 and it seems fine. Then again, I cannot tell whether other drivers would have performed better as that's the only driver I have tried for that bit of kit. It is odd that its release went by without any postings on this forum at all.

I will also try the NACL client on other PCs that I access - but only when there is a version that will work over my work network. And I will also try the android version once it is available for more than just Sony handsets.

Re: Declining performance - any advice?

The 750ti will need a driver update to avoid the errors - 347 and up seem to be the requirements.
The lower PPD could just be the mix of WUs being seen - core-18 on Maxwell gets roughly half the ppd at the moment, but the latest drivers and beta core seems to fix that.
Hope that helps

Yep. The mix of work units assigned is always fluctuating as old projects finish and new projects start. Long term PPD will average out but will never be constant.

Full logs can exceed the posting limits but there is often useful information if you just trim it down to something approaching the limit. For example, I could have picked out recent GPU WUs without having to ask you for them. (No big deal, though.)

As far as mVodoa divers are concerned, they have divided their downloads into two choices: Legacy GPUs and up-to-date GPUs. (I'm not sure if the drivers for your GT9880 and GT250 would have coexisted happily with drivers for one of your GTX 7x0 or GTX 980 but so far I have not needed to know that. Even if they do, it would require two downloads.)

In any case, rwh202 is right about a strong recommendation to update the drivers for all GMxxx (Maxwell) hardware (Rig 4 in particular). That may be the sole cause of your reduced throughput since the Force RMSE error / BAD_WORK_UNIT / SEND error:FAULTY errors would have been eliminated. At the present time, updating the drivers for the GKxxx GPUs is optional.

Thanks for all the advice

On long-run performance, I agree that it should level out - but my weekly stats at are all over the place, as can be seen at: Image

As for updating the drivers for rig 4, FAH reports the GTX 750 as a GM107. It's not a Ti card and I thought that, in that case, the Maxwell drivers would halve the card's performance? Happy for that to be wrong ....

I baulk at trying to install two Nvidia drivers on one machine - is that even possible? Certainly the legacy and new graphics hardware did not seem to want to coexist under one driver, regardless of version. Problems were compounded by the need for two versions of FAH as well.

I couldn't find online an earlier version than 327

Again, thanks

The gridpoint on 01.04 and the next grid point are below the green band but the gridpoint on 01.18 is above the green band. That simply indicates that some of the results from the first two weeks were delayed and appeared in the third week. 7im already said that things average out over time. I'd start at 10.12 (probably when your last system came on-line) and draw a horizontal line to the right. If that were the trend line, you'd have trouble arguing that it shows declining performance.

The GM107 is a Maxwell. Drivers for GMxxx require CUDA 7 which comes with the new drivers to avoid aborted WUs. I have not isolated the GMxxx portion of my performance data so I can't comment on a possible loss of Maxwell performance (other than aborted WUs, which are easy to spot). Perhaps you can fold the first half of a WU with one set of drivers, replace them with the other set of drivers, and finish the WU to give us a bit of data.

Hi Bruce

Sure. So, I replaced the 340.52 driver for the GTX 750 with the 347.52 version, 45% through a Core 17 WU for Project 9201.

(I had previously tried to downgrade to the 327 version but that installer decided that there was no compatible hardware and gave up.)

At the start (i.e. at 45.00% complete), FAH showed 6.04 mins per TPF, with 5 hours 33 minutes to complete the WU at an estimated total credit of 19,470 on a base credit of 8000, with estimated PPD of 46,214.

Just a few minutes before completion. FAH showed 6.06 mins per TPF, with 0 hours 2 minutes to complete the WU at an estimated total credit of 19,139 on a base credit of 8000, with estimated PPD of 45,882. On completion FAH reported 19,087 credits.

So it looks as though upgrading the driver had no significant adverse or positive effect, although there's a slight drop.

I will stick with it until the fixed nvidia driver arrives.

In my reading of the general sentiment around the forum, 347.52 IS the fixed driver.
