Cuda error 'cudaGetDeviceProperties( &cDevProp, i )' in file 'd:/BTR/SETI6/SETI_MB_CUDA/client/cuda/cudaAcceleration.cu' in line 135 : initialization error.


I'm running MB_6.08_mod_CUDA_V10.exe with BOINC 6.6.20 on Windows XP equiped with a GeForce 8400GS. The driver is 6.14.11.8208 (Feb 2009).

Reboot OS. CUDA app can't be run with other graphic intensive apps like games.
This error appears when no CUDA-capable card available at all. I recived such errors when replaced CUDA-capable 9600GSO with Radeon HD 4870.

I have rebooted several times. The CUDA device is there and seen when BOINC starts, but later I get the error again and I end up with more trashed WUs.

I have just updated the driver from 182.08 to 182.50 and changed BOINC from Daemon mode. Maybe these two changes will help.

arkayn:
CUDA does not work properly or at all when BOINC runs in Daemon mode, so the install into normal mode should fix the problem.

It's a WinXP system, so daemon mode is possible according to what I've read. Definitely a problem on Vista, though.
