I've Mathematica 8 installed on my laptop with Ubuntu 11.04 64bit and with nvidia drivers (ver. 270.41.06). The graphic card is a GT 330M. The CUDALink works flawlessly with the paclet version CUDAResources- Lin64-8.0.0.6 but not with the newest version CUDAResources-Lin64-8.0.1.2. The environment variables are correctly setted: export NVIDIA_DRIVER_LIBRARY_PATH=/usr/lib64/nvidia-current/libnvidia-tls.so export CUDA_LIBRARY_PATH=/usr/lib64/nvidia-current/libcuda.so so I'm really puzzled by this behavior. The answer of CUDAQ[] in the case 8.0.1.2 is False while CUDAInformation[] reports it's not able to initialize the cuda driver (which are anyway correctly detected). Does anyone know what it's going on here? Thanks. -- ...and I will make them pay for what they've done! (J.L. Picard)
