Hi,
I’m trying to run a code similar to the nbody NVidia’s example. I’m getting the error “Error: only 0 Devices available, 1 requested. Exiting.”, which causes a seg fault.
The output of the execution:
./nbody Clouda_config.conf
is

I’ve already posted on [SOLVED] NVidia/CUDA error : "0 Devices available" / Kernel & Hardware / Arch Linux Forums
What I don’t get is that the deviceID is set to 0 explicitly in the code. Maybe I got a file or link missing ?
Any help would be appreciated !
Thanks
