I recently bought a Card with a gt210 GPU, but CUDA does not detect the card. Graphics work fine, including OpenGL, but when I run deviceQuery, all I get is:
CUDA Device Query (Runtime API) version (CUDART static linking) There is 1 device supporting CUDA Device 0: "Device Emulation (CPU)" CUDA Driver Version: 2.30 CUDA Runtime Version: 2.30 CUDA Capability Major revision number: 1 CUDA Capability Minor revision number: 2 Total amount of global memory: 536150016 bytes Number of multiprocessors: 2 Number of cores: 16 Total amount of constant memory: 65536 bytes Total amount of shared memory per block: 16384 bytes Total number of registers available per block: 16384 Warp size: 32 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: 1.40 GHz Concurrent copy and execution: Yes Run time limit on kernels: Yes Integrated: No Support host page-locked memory mapping: Yes Compute mode: Default (multiple host threads can use this device simultaneously) Test PASSED Press ENTER to exit...
I am running Ubuntu 9.04.
The card is listed in “lspci” as
20:00.0 VGA compatible controller: nVidia Corporation Device 0a65 (rev a2)
I checked the permissions of /dev/nv* and they are both 666. I even tried changing the owner to my user, but that did not help either.
Any ideas on what the problem is or how to debug it?
