Before reading Simon Green’s post above, I placed an order for a Zepto Znote 6224W laptop, thinking that an 8600M GT card with 512MB should work without problems.
It arrived yesterday, and my CUDA experience in XP is a mixed bag. I have tried running the executables in the SDK, and the good news is that it seems like regular CUDA is working fine. The bad news is that I have had no luck with the executables that use OpenGL interoperability to draw stuff.
DeviceQuery reports my 8600M GT just fine, and the bandwidthtest gives impressive figures. Executables such as MatrixMul, scanLargeArray and simpleTexture work too. But SimpleGL just gives the error message “GPU interoperability on multi GPU systems currently not supported”, and so does fluidsGL. Interestingly enough, simpleD3D seems to work fine while fluidsD3D just prints the error message “failed to find a G80”.
As Simon Green hinted, the Nvidia drivers refuse to install, telling me that no supported hardware could be found. So I am stuck with the drivers provided by the seller.
I noticed the comment about OpenGL interoperability not working when using multiple displays and was hoping I had found the issue. But setting this option to “single display performance mode” did not change the behavior in any noticable way.
Is there any issue that I have overlooked that could be the cause of OpenGL interoperability not working? Or is there a way to make the 8600M GT pose as a regular 8600 GT card and install the regular drivers?
I invested a fair amount of money in this laptop expecting to use it for CUDA development, so the thought of not being able to use the hardware due to driver issues is quite depressing to me. I would really appreciate any sort of guidance that could help me get CUDA working fully on this laptop.
