First, I have built Fedora7 environment on my research desktop that has Geforce8800GT for displayer. Then, I have installed NVIDIA-Linux-x86-171.05 driver after connecting S870 to the desktop using the two special cables. Next, I have followed the release note to set up the CUDA Development Environment. Finally, after succeeding â€˜makeâ€™ process in the projects directory, I could run some example binary files. Then, I could see the following error message when I ran matrixMul file.
[root@CUDA release]# ./matrixMul
NVIDIA: could not open the device file /dev/nvidia2 (Input/output error).
There is no device supporting CUDA.
If someone knows this problem, please let me know the solution.
