I have a Dell D830 laptop with a Quadro NVS 140M. I am unable to get the CUDA 2.0 beta working on this computer.
I have installed the 174.55 driver, the toolkit and SDK. When running the deviceQuery sample, no CUDA hardware device is found, and the emulation device is used instead:
There is no device supporting CUDA. Device 0: "Device Emulation (CPU)" Major revision number: 9999 Minor revision number: 9999 Total amount of global memory: 4294967295 bytes Number of multiprocessors: 16 Number of cores: 128 Total amount of constant memory: 65536 bytes Total amount of shared memory per block: 16384 bytes Total number of registers available per block: 8192 Warp size: 1 Maximum number of threads per block: 512 Maximum sizes of each dimension of a block: 512 x 512 x 64 Maximum sizes of each dimension of a grid: 65535 x 65535 x 1 Maximum memory pitch: 262144 bytes Texture alignment: 256 bytes Clock rate: 1.35 GHz Concurrent copy and execution: No
I have verified that the 174.55 driver is installed: the correct driver version is reported by Device Manager and dxdiag.
DirectX hardware accelerated rendering is working correctly, but the in addition to CUDA not working, hardware accelerated OpenGL rendering is not working either. OpenGL applications fallback to the GDI Generic device.
