One long WU is probably not enough to know it's running without problems, but you never can tell.

I just got one of the famous xMG WUs on my EVGA GTX 650 Ti with 2GB:
25x2-NOELIA_1MG_RUN-0-2-RND7421
OC Scanner says: GPU load 93%, MemLoad: 1537 MB, MCU Load 45% after 2.5% advanced.
It's the first of those on this card, I will keep you informed.

I do not understand is that with short tasks work perfectly my GTX770 (Ubuntu 13.04) and the long NOELIA failure, so far I have not tried with a different long task.

I think the problem is in Noelia tasks.

The NOELIA tasks make the error in the driver appear, but they are not causing it. Noelia is testing new functionality, that's why the error doesn't appear with short queue tasks or other long-runs.

Again, the exact problem you're describing has been seen by at least 2 others and has been solved by downgrading the driver. That's the best we can offer, including the .inf mod propsed by Zoltan. Or keep it running under Win, of course.

Such a pity about the NOELIA tasks: wasting energy and computer resources.....

Noelia is trying to make new functionality work, and GDF said they definitely need them. So while the execution of these tests may be lacking, the results are not worthless. I wonder if they'd be better off in the beta queue, though.

Hello: Thanks for the comment.

I'll wait for the final output of Nvidia 325.08 driver for Linux (currently in Beta, I do not think that take) and see if it solves, if anything I can always move to Windows without problem.

Many thanks:

Yes, I think these would be better in the Beta queue so we would be able to decide whether we want to take the risk of their failing. Good suggestion!

I just got one of the famous xMG WUs on my EVGA GTX 650 Ti with 2GB:
25x2-NOELIA_1MG_RUN-0-2-RND7421...

I, too, just got my first xMG (44x5-NOELIA_7MG_RUN-0-2-RND1940) for my GTX 570. Holding my breath...

I see Nathan WU's back in the Long queue.

My last NOELIA worked fine on Linux 304.88:

FAQ's

HOW TO:
- Opt out of Beta Tests
- Ask for Help

I've tried the latest (320.49) driver on my least reliable host (it has a WinXPx64), and it became completely unreliable :) Every (Noelia) task is stuck at 0% with 0% GPU usage using the 320.49 driver (btw it's CUDA 5.5).
I'm reverting to the driver downloaded by the Windows Update (307.9)

Hello: In Windows 8-64bits I am using the 320.49 without problems, both short tasks like Noelia.

I have mentioned it before: my quad core with Vista x86 is using driver 320,49 with a GTX550Ti and has relative the least errors from my rigs. It does the Noelia´s but very slow, but that´s the card. It seems a bit "bad luck". I have checked a lot of my WU´s and the wingman (in case of error) and I saw a lot "error while downloading", thus even before the Noelia´s WU.

I, too, just got my first xMG (44x5-NOELIA_7MG_RUN-0-2-RND1940) for my GTX 570. Holding my breath...

Okay, so that wasn't so bad:

Run time 65,793.69
CPU time 3,755.88
Validate state Valid
Credit 150,000.00

Per GPU-Z, Avg GPU Load = 85%, Max GPU Memory = 1050MB

---

No the Noelia´s warn´t to bad. I have Nathan´s again and I see a GPU load between 82-88% and a MCU load of 28-30%, GPU time and CPU time almost the same.
Noelia´s had 93% GPU load and 37-45% MCU load and used little CPU.

The Noelia _MG7_ on the GTX660 with 1% MCU load finished without error!
7043246 4587792 154818 12 Jul 2013 | 15:39:52 UTC 16 Jul 2013 | 21:56:27 UTC Completed and validated 192,242.79 83,933.54 100,000.00 Long runs (8-12 hours on fastest card) v6.18 (cuda42)

The time from more than 2 days of course is no joy. I will try a short run. If the card does not crunch properly then I remove it from the quad core with x86 Vista.

Sadly I wish I could agree - the NOELIA_klebes have been running ok (just about) however the *MGs have been a nightmare. I noticed GpuGrid's total performance has dropped by some 15% in the last 3 months - so I guess the jury is out on that.
Unfortunately communication has been 'limited at best' on the new WU's, no hardware requirements, no details on the level of testing they have gone through, what they are for - nothing.
I just hope the quality of the science is up to a higher standard than the management of GpuGrid at the moment otherwise I suspect we are all wasting our time and money.

And another one bites the dust... 4x2-NOELIA_1MG_RUN1-0-2-RND8035_3. I guess I shouldn't pile on.

I just got one of the famous xMG WUs on my EVGA GTX 650 Ti with 2GB:

The above WU finished successfully! I checked memory load several times and it was always about the same: 1500 MB.

GPU time: 73,064.51 s, CPU time: 33,299.85 s, the low credit is due to my low up-load speed - missed 24 deadline again…

So I am pretty satisfied with my GTX 650 Ti with 2 GB memory. The only sad thing, I just purchased one of the two cards on Amazon “used – like new” for the same price well below the 1 GB versions (new and used). Missed an opportunity…

I'm currently crunching one of these dreaded NOELIAs on my 1GB 650Ti:

Slot: 0
Task: 35x11-NOELIA_7MG_RUN3-0-2-RND0597_0
Elapsed: 10:30
CPU time: 04:43
Percent done: 24.66
Estimated: 42:35
Remaining: 32:04

It's consuming 622MB on the card, CPU usage is ~45%, so it appears to be progressing normally - sorry, no GPU load info, I'm on Linux.

Let's see how it goes!

Another 'wonderful' unannounced WU: NOELIA_2HRUN - 25% in 7.5hrs (30hrs estimated) on a 1gb 650ti.
Terrific..

re: NOELIA_2HRUN - at least it appears to only be using 714MB GPU mem(of 1024MB); mem controller usage is low at 21% (normally 41% for non NOELIA); GPU usage 99%, CPU 30%.

It is a good thing that I retired my 1GB GTX 650 Ti, since my 2GB GTX 660s are now getting only the larger work units.

I am presently running 2-NOELIA_2HRUN at 1406 MB, and a 44x1-NOELIA_1MG at 1135 MB. The former is running at only a 5% memory load, but I will just let it run and see if it completes. Maybe that is the way it is supposed to work? Since nobody tells us, we are left to figure this out for ourselves.

Maybe a memory allocation issue has been fixed. Noticed against the task properties the NOELIA estimated app speed is 96.06 GLFOPs/sec (650ti) whereas a SANTI_bax is 516 GLFOPs/sec (670ti @ 72% power). Normally my 650s are about 70% the performance of my 670 - wondering if double precision is being more heavily used? There again its is probably more related to cache size (256k v 512k).

MW ist the only Project that needs DP.
