No suitable GPU ?

(moderation:
When I launch BOINC it says there is no suitable GPU. I have a GTX 260 MaxCore graphics card that is CUDA, OpenCL and everything else.
No matter to me if BOINC does not like it.

Do you have installed BOINC as a service (Protected Application Execution mode)? In that case, BOINC wouldn't be able to find/use the graphics drivers.

Also, if you haven't got BOINC installed as a service, did you install the Windows supplied drivers for this videocard, or the drivers from Nvidia? You will need the latter drivers, if you want BOINC to see the GPU. The Windows supplied drivers have the CUDA part disabled.

Then you installed it as a service. You will need to uninstall BOINC through Start->Control Panel->Uninstall a program. Then reinstall it and in the 3rd screen in the installer (see here for an example), click the Advanced button. Then uncheck the "Protected application execution" option, before continuing to install BOINC.

Hi,
I use a GTX260 as well, it works.
Last week I tried the driver update. All tasks failed, not only E@H, also Seti and Milkyway.
I downgraded to an older version, its working again.

Sorry Ian, they don't like that.

I'm not sure this is what Ian had in mind. Once you get GPU tasks working for BOINC, boinc will run at most as many ABP2 CUDA tasks as you have GPUs in parallel. You will still get CPU tasks in addition, because otherwise your CPU will be partly idle (and we don't want idle, do we :-) ).
The discussion Alex quoted was about forcing one or the other type of CPU tasks, it is not really related to GPU tasks.
Happy crunching

RE: My GPU is vastly

Both CUDA and OpenCL will still use the CPU. CUDA will still use it for translation of the tasks to something the GPU can understand, for transfer of the data to the GPU's memory and back to disk. You cannot run any GPGPU applications on a GPU only as there is no OS that understands that.
OpenCL will use all computing hardware in a computer, be it CPU, GPU or other (the Network Processing Unit comes to mind). While the first demos of OpenCL may only use a CPU or a GPU, you'll find that they only use one of these per demo. So if you have 4 cores and 5 GTX 295s in your system, any OpenCL demo at this time will only use either 1 of the cores, or 1 of your 10 GPUs.
Only somewhere in a near future will they want whatever work is done to be done in parallel by all your computing hardware.
Since you feel that the Einstein admins are vastly inferior to your programming awe, why not tell them you're here to help? Take their source code and engineer your superior own version, show them what can be done with it?
Go on then, given your superior knowledge of how to do these things, it should be easy. You'll whip up a working application in 24 hours and offer that for testing for the crew. You'll make it all 64bit as well. On top of it all, you'll do this all for free as you're in a helping spirit! :)

Ian, your signature contains a link to a commercial site seeking moneys - hence is deemed by forum policy to be a commercial advertisement. In addition your post content also contains indirect commercial inducement.
Normally such posts would be deleted without prior warning. As you are a new member, thus possibly not fully aware of forum policy, I simply direct that you promptly alter your signature and refrain from commercial inducement in the future, lest you be subject to moderation without further discussion in the usual way.
Cheers, Mike.
