21) Questions and Answers : GPU applications : Where to download standard cuda application and modify app_info (Message 969421)
Posted 9 Feb 2010 by Harri Liljeroos
Thank you for your reply Sutaru,
I solved the issue by downloading the Lunatics Unified Installer 0.2 and took the Cuda 2.3 dll's from Einstein. The temperature is now controlled by the TThrottle and I set the max GPU temp to 81°C. For Einstein the throttling is activating only sometimes but for Seti it is almost constantly active and the application is throttled to 25...35 % to keep the temperature at 81. This of course slows down the calculation. I am wondering if it would make any difference if I'd use the 2.2 dll's. Probably there would be less throttling but calculation would take the same amount of time.

It is difficult to compare how the computer is now doing as there aren't many this kind of GPU's around (CPU T9500, GPU Quadro FX 3600M: peak GFLOPS 160)

I don't have a cooler for the laptop, but it is raised about 1 cm above the desk to let the air flow freely.

That's what I'll do, but first I will drain the cache (1+1 days) by setting NNT and let it finish all WU's. Maybe the temps would stay down if I could somehow get hold on the older cuda 2.2 version of the science application (6.08?).

Hi,
I am trying to set up my laptop to use optimized CPU applications and use at the same time standard cuda application. The reason for this is that the laptop's gpu does not have a fan of it's own and is running too hot with optimized cupa application.

When using only Lunatics optimized CPU applications the GPU temps get around 75 degrees celsius. With optimized GPU application the temps get around 87 degrees. I am now using the GPU application for Einstein which does not use much of the GPU and the GPU temp is then about 81 degrees.

So I was wondering if using only the standard SETI cuda application I could keep the temp down and still use the GPU. So I'd like to know where to find the standard gpu applications and if someone had a ready formulated section for the app_info.xml using that application. I deleted from my current app_info the section for gpu to not use the optimized application.

Dang it...

I just got asked the question, and I can't remember the answer, or if there is one...

Is it possible to verify the Cuda dll version that you are currently running?


Using Process Explorer from www.sysinternals.com you can see what dll's are being used by different programs. You need to set the GPU processing always active so that you can select the running exe without the program exiting. Or at least you have to very quick. Maybe you can make the Process Explorer to write things to a log file, I haven't studied it so thorouhly.

Does the backoff work only halfway if it was only affecting the CPU requests and not the GPU requests? If a request to server is made anyway shouldn't it then ask work for both GPU and CPU at the same time if host is lacking work for CPU and GPU?

Thank you for your answers. Things have moved along and CPU work has now been downloaded and the host is cruching now.

Hi,
I just run into a situation where boinc does not request any work for my CPU, only for GPU. CPU has nothing to crunch at the moment.

I'm attached to 4 projects with following shares: CPDN 30, Einstein 25, LHC 150 and SETI 100. CPDN and Einstein are NNT (Einstein is down anyway), LHC doesn't have anything to crunch so that leaves only SETI. But CPU is just idling. This system has previously been doing both GPU and CPU WUs (last 6.03 CPU WU finished yesterday). Since then CPU was doing Einstein and now those are finished too (5 ready to report and 5 uploading).

Boinc is 6.6.36 (WinVista 32), opti apps SSSE3 (Lunatics 0.2 Unified Installer w. VLARnokill), CPU=Q9400, GPU=9800GT (driver 190.38, CUDA 2.3). Preferences are set to accept all kinds of work and all types are in my app_info.xml

I switched on the log_flag for work_fetch_debug and here is output for that:

Can somebody interpret why Boinc is not requesting any work for the CPU?
29) Message boards : Number crunching : Anyone else have issues with the new Nvidia driver? (Message 924032)
Posted 6 Aug 2009 by Harri Liljeroos
I have noticed that with the 190.38 driver version (Vista 32) my 9800 GT does not use DVI-D anymore when showing the desktop (1600x1200), it uses DVI-A. Previous driver I used was 182.50 and it did use DVI-D which gives a slightly better picture. I remember having similar issue with some earlier update as well. When I restart the computer monitor states that during post it is actually using DVI-D 1600x1200 but when the graphics kick in the signal changes to DVI-A 1600x1200.

The card is from MSI and so was the driver 182.50 now the driver is directly from Nvidia. Could this be the reason?

Posted 6 Aug 2009 by Harri Liljeroos
I've done a little more testing. The Firefox yesterday updated itself to 3.0.13 but that didn't change the behaviour. I have the front page of message boards bookmarked (managed with the Xmarks addon) and if I use this bookmark to go to the message boards front page and click from there one of the boards (like Number Crunching) the log in is somehow lost. If I navigate from Seti's homepage -> community -> message boards -> number crunching log in is not lost.

On one computer the message board front page even looks a little different (font size) depending on the way I go to that page, using bookmark or navigating from the homepage.

NEWS FLASH: While writing this I was doing some tests and noticed that my bookmark points to a different http-address than what I get when navigating. Bookmark: setiweb.ssl.berkeley.edu vs. navigating: setiathome.berkeley.edu

Both seem to have all the latest messages visible but the setiwaeb.ssl.berkeley.edu won't keep my log in alive. It seems I have to modify my bookmark.

The problem is back. I have now these message boards open in two tabs in Firefox. In this tab where I am writing this message I can see the yellow marks for unread messages. On the other tab clicking "Account" on top of page always gives me the log in screen (I have stay logged checked on that page) and after logging in I can see my hosts with other data (so the log in was OK) but the message boards won't show the yellow "unread messages" marker and clicking the "Account" gives me the log in screen again.

If I view a thread and click "post to thread" I get the log in screen again and after logging if I return directly to the message thread the yellow markers are there.

So does anybody have a glue what is going on? Does anybody have same problem? Firefox was yesterday updated to 3.0.12.

Today I am no longer able to stay logged in here. This happens on all computers I've tried so far. Using Win XP and Win XP64 with Firefox and IE7.

Has something changed here on the web pages?

34) Questions and Answers : GPU applications : New version 6.6.31 not exiting? (Message 908327)
Posted 17 Jun 2009 by Harri Liljeroos
This works at least on 6.6.36:
- open a command prompt window and go to "\Program Files\BOINC\" directory
- there is an executable program boincmd.exe, run it with parameter --quit
- this should shutdown boinc and the science apps

Posted 3 Aug 2008 by Harri Liljeroos
If you are using anonymous platform, how does the server know if you have all applications installed on you computer? Does it have any other way but to send AstroPulse WU's? Then BOINC could report back to server that applications were not found and mark the WU's in question rejected or something.

Thank you for the link. I removed Boinc using installer without deleting manually any files from Boinc folder. Then copied all executables and now everything seems to run OK and I didn't loose any WU's.

Thanks again!
37) Message boards : Number crunching : Unable to install Boinc 5.8.15 (Message 524044)
Posted 27 Feb 2007 by Harri Liljeroos
Hi,
I've been updating Boinc to my computers but on some of them without success. Out of six computers so far three has failed. OS (win2000, win xp) and previous versions of Boinc (5.4.11 and 5.3.12) vary on these hosts.

After I stopped boincmgr and boinc daemon I run the installation package (single user install) and everything seems to progress as planned but when installation routine tries to launch Boinc it gives error: Internal error 2753. boincmgr.exe

Manually starting Boinc starts the previous version like nothing new was ever installed. On two computers none of the executable files in Boinc folder has been changed, on one computer only boinc.exe was changed from 5.4.11 -> 5.8.15 but boincmgr.exe is still 5.4.11.

Rebooting and reinstalling (repair) does not make any difference. Removing Boinc completely may be next step but I am unwilling to do it just now as two of these host have about 2000 hours worth of unfinished workunits for CPDN.

On three computers updating went just fine (win2000,winXP, winXP x64 and Boinc 5.3.12).

Anybody have similar experinces or pointers how to solve this without removing Boinc first completely?
