I recommend 6.5.0...

I update to 6.6.23 ans I have always the same failure :/

I've had no issues w/ 6.6.20 on Linux 64-bit. Then again, I only have a measley 9600 GSO....:-( Not even SLI, just the one card.

I had some hanging tasks. Upgrading Nvidia drivers from 182.06 to 185.85 seems to have cured the problem (and the WUs run a bit faster also).

I had a never ending wu on a boinc 6.4.7

it's a IBUCH_KID

this wu

it took me 5 days to realise, as the computing card is far from where I live and work.

@Paul: the cygwin appears relatively often in error messages, so I think it's related to the compiling machine.

@Michael: the bug solved with 6.6.23 was first described as WUs taking about 4 times longer, not really hanging. So one would have to watch the machine or the RAC closely to spot the problems. And I don't know how different the win and linux builds are, the problem may very well not exist under linux.

Cuda error: Kernel [fft_data_swizzle_out] failed in file

Cuda error: Kernel [copy_mul] failed in file 'com.cu' in line 46 : the launch timed out and was terminated.

If you want 6.6.20 to work good, you must do clean install.

Uninstal your previous version of BOINC

Delete all files and folders of BOINC

Instal 6.6.20

Have fun.

I do this and no problem so far.

Well yes i reset the debts a few times a month not sure what it does screw up though but works fine for me.

Hello. Sorry i bad speak english. I used boinc 6.6.20 and my work never end. Why? My system: XP x64, GPU: gf 9600GT
last version nvidea driver

Well yes i reset the debts a few times a month not sure what it does screw up though but works fine for me.

somebody will prompt that to me to do? upgrade to the version 6.6.23 ?
How many on time occupy calculations on 9600 GT ?

Greetings! I upgrade BOINC to version 6.6.23, GPUGRID do not work! Writes "Waits for the turn" and calculations do not go! ((
Please write what version of the client the working and what version of the driver approaches is better?
P.S. XP x64, GeForce 9600GT, driver: 182.50
Please help

I also don't understand what you mean, but I guess this is the answer.

MrS

I thought I'd prepared to use more than one CUDA - BOINC 6.2.28, and created cc_config.xml. However, only one CUDA is recognized. I tried upgrading the driver for my Nvidia 9800 GT using the Microsoft option to do this; however this actually downgraded the driver from 7.15.11.8250 to 7.15.11.7578 instead and stopped any BOINC use of the CUDA at all until I reversed this downgrade.

Where can I find the proper site to look for new drivers and is there any other one recommended for this card?

Where can I find some Nvidia software for counting the number of CUDAs present to see if the expected second one was actually installed?

Does an Nvidia card CUDA need a monitor attached before GPUGRID can use it? I don't have space to add a second monitor.

In case it makes any difference, I also installed the 64-bit Vista SP2 update on my machine about this time.

What did you put in your cc_config file. Was it like this?

<cc_config>
<options>
<use_all_gpus>1</use_all_gpus>
</options>
</cc_config>

You can download nvidia drivers directly from the nvidia web site here. It would seem the 182.50 drivers are more reliable with GPUgrid work, even though they aren't the latest any more.

I understand that you may need to extend your desktop onto the other card to get it to see it under Vista. I use XP which behaves differently.

I have to use remote desktop into my computer with the CUDA card for business purposes and it keeps crashing the runs. Strangely I've been doing this since I started with the project months ago and it only started causing problems recently. Since I can't get around it (if I log in and try to pause the job it will crash the unit before I can even get to it). Thus, I'm detaching from the project since it's taking too much time to try and figure out the issues and if remote desktop is going to act like that I have no way forward. It's been a pleasure and best of luck to the project.

I'm running Vista 64bit with SP2 and things are running fine. I didn't extend the desktop or any other changes, other than to disable SLI. You have to do that to let BOINC see each card as a seperate device since CUDA doesn't support SLI yet. Also, check after updating drivers since I've seen that installing a new driver turns SLI back on sometimes. The SLI limitation is an issue with nVidia since they develop the CUDA language. You'll see that after you turn it off, in the messages you see when you start BOINC back up each card now shows as a different CUDA device (exit out of BOINC completely before making SLI changes so it can redect). The other thing to watch is heat on the video cards. I have to set my machine to crank up the fans on the video cards to about 95% speed to keep them cool while doing CUDA processing. If your cards overheat, you'll get errors and crashes. Otherwise, latest drivers and turn off SLI and mine is humming along on every project I run.

Where do you find the software to disable SLI under 64-bit Vista SP2?

By the latest drivers, do you mean 182 series or 185 series? For what Nvidia card?

How do you exit BOINC completely? I've found that since the Vista SP2 update, at least for the 32-bit version, you need to exit BOINC completely to allow full backups to complete without fatal errors, and I'm looking for a way to do this that doesn't have errors in all workunits already in progress as a side effect.

The latest driver available from Nvidia is 185.85. To disable SLI right click anywhere on your screen & open NVIDIA control panel. From here left click on "set multi-GPU and PhysX configuration". Then sellect "Do not use multi-GPU mode" then click on the "Apply" button at bottom of window, this will turn off SLI. To switch on SLI just reverse process (more or less). All that is required to see both GPU's on this card is to disable SLI. No need to extend desktop. Try with SLI disabled first, should be OK.
I am running 64 bit Vista SP2 with 185.85 driver and BOINC 6.6.31 on an Nvidia 9800 GX2 (dual GPU) with no problems. I normally exit BOINC by right clicking on the BOINC icon in the task bar & firstly set "snooze" and then sellect "exit". I found that if I just exited BOINC then the tasks would remain running. The 9800GX2 is a hot card, which seems to like running at 80-85 degrees C. I have left the fans on automatic and have noticed no issues to date.

This will tell you the info about your cards and if SLI is enabled, I think!

My nVidia control panel appears a little different from what others above described, but it may be hardware related since I'm running multiple GTX260's. In my control panel, go to the section for 3D Settings, then under that Set PhysX and SLI Configuration. On that page, section 1 is for PhysX, choose enable. In section 2 for SLI, click Disable. Then click the apply button. It will take a few seconds and you may see your screen blink off for a second.

To exit BOINC, simply rick click the icon in the system tray and choose exit. If you have the manager window open, go to the file menu and choose exit. If the project software is written well, it should save the work and pick up where it left off next time BOINC runs.

Oh, and I am running nVidia driver version 185.85 and BOINC version 6.6.28.

I opened the NVIDIA control panel and found a section labelled Set PhysX configuration, but nothing referring to multi-GPU mode.

What type of graphics card are you using ? If it is a single card with a single GPU then SLI will noy apply, and can be ignored. SLI is only used to link the 3D rendering functions of multiple display cards or cards with more than one GPU.

I have a Geforce 9800GT. The specs that came with my computer weren't very clear on whether there's more than one. I'm no longer able to lift the computer and check inside. The specs did suggest that it should be able to control two monitors, though.

I just had a long running task running 6.6.23
It took 17hours elapsed

Task: 452-GIANNI_BIND

Ok so 2D clocks would indeed cause the slowdown...
I've also had an issue with S@H tasks taking longer than they should (~20 min each versus about 7.5min) and eventually one errors out and locks up the computer.
I dunno whether its cuda or the apps but this is indeed a problem.

I don't know, I'm using 6.6.20 with no problems, But then like another poster I run XP x64, I tried 6.6.28 and the WU's that I have were put into permanent waiting mode and My video driver is 185.85(NV and WHQL approved) and so I went back to 6.6.20, 6.6.31 to 6.6.36 seem to be having problems, Some of It gpu related.
