Yes, now, after a second uninstall/reinstall, everything seems to work fine again. Thank you.

Here's my app_info.xml file, generated by the Lunatics installer. I only changed the <count> values.

I don't really understand what's going on, I got this error once, but the subsequent requests succeeded. I didn't do a thing between these requests.

So for now it's working fine again, but I'm interested what could cause that behaviour? Shouldn't this error be persistent?

4) Message boards : Number crunching : "Your app_info.xml doesn't have a usable version...." and "Can't link app version file" errors (Message 1387325)
Posted 3 Jul 2013 by Profile Helsionium
Hello,

a short time ago (few hours maybe) I started to experience errors I din't have before.
All of a sudden, I get "Your app_info.xml doesn't have a usable version of Seti@home v7" - I have installed the latest Lunatics optimized apps, already tried uninstall/reinstall and detach/reattach. The app_info.xml looks normal, it's the same as it was before (working fine ever since v7 was released).
At the same time I noticed all GPU WUs had errored out, with the error message "Can't link app version file".

Today, I installed a new GPU (GTX 660 in addition to the 680 I already had) and updated to the latest stable drivers, but I doubt it's related, as it worked fine for a few hours after that.

If you need more info, just state what you need.

Your help is very much appreciated.

Posted 16 Mar 2013 by Profile Helsionium
I'm using x41zc_cuda50 and the AP nVidia OpenCL application on my only machine (GTX 560 Ti + GTX 660) so my results aren't entirely comparable with your situation, but here's what I found out:

- Running 3 WUs is possible, but it's not worth it. The GPUs are maxed out with just 2 WUs anyway. With 3 WUs, there was somewhat higher power usage and temperature and occasional slowdowns. There was no noticeable positive effect on processsing throughput.

- With 2 WUs some moderately GPU-intensive programs still work without major problems (e.g. Google Earth, HD video), but with 3 WUs they wouldn't, even if there was still enough VRAM free.

- If any CPU-intensive task runs at the same or higher priority than the GPU tasks, this can cause massive slowdown. So I run the GPU tasks in high priority AND make sure no other CPU-intesive tasks run in high priority.

But keep in mind that this (except that last point) might be different when using x41g.

Posted 5 Mar 2013 by Profile Helsionium
Sorry for resurrecting this old thread, but I want to note that the problem has finally been solved.

My card, the "Zotac Geforce GTX 660 Ti AMP! Edition" is factory-OC'ed to 1150 MHz core and 1650 MHz memory clock - voltage already maxed.
The solution was to reduce the memory clock to 1500 MHz. It's running fine for days now (at core frequency 1200 MHz). Any higher value, particularly 1530 MHz and up, caused the driver to occasionally crash (with x41zc_cuda50; the previous x41g only caused the "zero status..." problem but no driver crashes) and whenever the driver crashed, the clock frequencies would be reset to factory and constant crashes (every 20 seconds or so) would happen from that point on.

I didn't notice this solution earlier because I never thought I had to decrease memory speed by that much. Anyway, it's fine now.
Thank you, jason_gee, for all your help.

Kind regards,
Helsionium

Unfortunately I corrupted my BIOS due tue a very badly designed BIOS update procedure. Since I probably will not find a way to recover, I must wait a few days for a replacement motherboard. I'm thankful for all your ideas and will continue with your suggestions as soon as possible.

Posted 10 Dec 2012 by Profile Helsionium
OK, just to be sure, since I don't have any experience with the GTX 660 - the current core voltage is 1.175 V, core clock 1163 MHz, memory clock 1652 MHz, temperature 58-60°C. Is it safe to increase the voltage and what amount would you suggest?

Posted 10 Dec 2012 by Profile Helsionium
So, some new observations:

- Enabling hyperthreading didn't fix or reduce the errors, I still left it on anyways.
- The error rate seems to be lower with x41g so I reverted back. Might be a coincidence, but at the very least, x41zb is certainly not better in that regard.
- Number of tasks per card doesn't matter. I ran only one task per card over the whole night as opposed to my standard two, but the error rate was not reduced.
- I swapped the cards, the error still only affects the 660.
- A temperature issue can now definitely be ruled out, after swapping the cards, the 660 runs at a temperature of 58-61°C.

Also, I didn't find the SLI option to disable it. I didn't connect the cards with an SLI bridge, so it shouldn't be available, right?

Posted 9 Dec 2012 by Profile Helsionium
Thank you all for your opinions.

I used an old version of MSI Afterburner that couldn't make use of all the functions. With the new one I can indeed adjust the voltage (but can still not turn the fan speed of my 660 above 74% which is strange). But if, as you say, this is already a rather high temperature I'd rather not fiddle with the voltage control unless necessary. However, according to several internet sources, the temperature is pretty much the expected temperature of my card - the Zotac GTX 660 Amp! Edition - under maximum load, maybe a few degrees higher, but that's expected too (multi-GPU system, very demanding CUDA load instead of the game-based benchmarks)

I never enabled SLI to begin with, and also switched to "single display performance mode", but that too didn't help. I've set the process priority to high via the mbcuda.cfg file.

I'm out of time now, but tomorrow I will try switching the cards around and find out if hyperthreading affects the problem or not. The good thing is that the error is relatively benign and that all of the affected tasks I followed eventually successfully validated.

Posted 9 Dec 2012 by Profile Helsionium
The problem persists even after I did this:

- reduce CPU speed from 4.3 GHz to 4.0 GHz
- reduce RAM frequency from 1600 to 1333
- disabled XMP
- installed x41zb
- tested GPU with OCCT, no errors, no artifacts

I can't change the GPU core voltage on the 660, the software doesn't allow that. I didn't find any options to adjust Vdd in the BIOS. The 660 isn't overclocked (past its factory-overclocking) and the software doesn't allow me to go lower than the default clock rates, so I can't do this. The error is probably not related to temperature, though. There was one instance of the error shortly after reboot, when temperatures were still much lower.

Just shortly before the installation of the new 660, I disabled hyperthreading because it was recommended by some in this forum. Could that be related?
12) Message boards : Number crunching : CUDA problems (Lunatics) / zero status but no finished file (Message 1313022)
Posted 9 Dec 2012 by Profile Helsionium
Alright, I checked:

- Hard drive integrity: OK (and no processes interfering with BOINC or SAH)
- DPC latency: OK, consistently below 500 microseconds, sometimes slightly above 500 if BOINC is active.
- Command rate: OK, set to T2.

About the temperature: is 70°C already too hot? Both GPUs and the CPU typically run at 68-74 degrees under full load. According to the information I had, this is well within their specifications.

About RAM Vdd: I can't really check this now, as I want to avoid restarting the machine unless absolutely necessary. Can this be a problem with RAM? Why would that affect only the tasks running on the 660 GPU and not the older, but almost equally fast 560 Ti?

The power supply should be OK as well. The system ran just fine with two overclocked 560 Tis which used more power.

Posted 8 Dec 2012 by Profile Helsionium
Hello there,

ever since I replaced one of my two 560Ti GPUs with a GTX 660, a relatively large amount of tasks (I guess 20-30%) restart at least once (exited with zero status but no 'finished' file) after encountering this error:

Error on call (cudaMemcpy(PowerSpectrumSumMax, dev_PowerSpectrumSumMax, (cudaAcc_NumDataPoints / fftlen) * sizeof(*dev_PowerSpectrumSumMax), cudaMemcpyDeviceToHost)), file c:/[Projects]/X_CudaMB/client/cuda/cudaAcc_summax.cu, line 239: unknown error

Here is a stderr output from one task that restarted five times:
http://files.helsionium.eu/stderr-2739587852.txt

It seems this problem only affects tasks that run on the new 660. What could be causing it? The same system ran fine with the two 560 Tis before. This problem isn't particularly grave - all of the affected workunits eventually complete and validate but I guess it's still having an impact on overall crunching performance, aside from being a major nuisance.

I'm using BOINC 7.0.28 on Windows 7 64-bit, the Lunatics x41g optimized app and the beta driver 310.70 (same problem with the latest WHQL driver, though).

Thank you in advance,
Helsionium

Posted 22 Nov 2012 by Profile Helsionium
I had 5000+ ghost units as well. Since I decided that I'd rather crunch for other projects until the current issues are resolved, I purposely abandoned them rather then have them timeout over the next few weeks. This was at a time when I couldn't reach the scheduler or download server for days. Now that these issues are (partially?) resolved you might just as well sit back and relax, the ghosts will be resent eventually.

Posted 18 Nov 2012 by Profile Helsionium
I've asked the same question some time ago and I believe the consensus was:
The 500 series are currently the best for SETI@home and they are cheaper than the 600 series. However, they use significantly more power, something to keep in mind.

However, I'm waiting for the next iteration of the optimized applications, because they might render the 600 series more useful.

Hello,
I just noticed something strange - nothing grave, but possibly a bug:

On the application details page for my main host
http://setiathome.berkeley.edu/host_app_versions.php?hostid=6141926
in the section Astropulse v505 (anonymous platform, CPU):

Number of tasks completed: 231
Consecutive valid tasks: 233

How can there be more valid tasks than completed tasks?

Kind regards,

The important line is:

Installers have been temporarily removed pending resolution of some concerns related to licensing (20 Sept. 2012).


If I remember correctly, there were some licensing issues with Intel and Lunatics is working on resolving these issues. There's nothing that can be done about that, please just wait it out.

Posted 4 Oct 2012 by Profile Helsionium
I had a MSI P67A-GD65 mainboard, which does not carry this warning, which failed after about half a year of heavy usage (SETI@home optimized with 8 CPU threads and 2 GPUs). It may be a one-time thing, though. I never had any stability issues with this board befor or after the replacement.

While I was still running a dual-GPU setup, I had three (!) MSI N560GTX-Ti Twin Frozr II/OC that failed (the fans broke all three times) in nine months.
So far, it has only been an annoyance because all defects were covered by warranty, but I don't think I'll ever again buy MSI products. I had very good experiences with their products before, don't know why quality seems to have gone down so much.
