I'm going back and looking through some of the instructions now. So I guess when using CUDA, it is required to module load cuda/[version]?

I'm currently trying to run an experiment using GPU nodes in Abel. The Python program that I am using uses Cupy, which I have installed in my venv with pip. On my sbatch script, I set the GPU request as instructed on the Job Scripts page: > > > > #SBATCH --partition=accel --gres=gpu:1 > > > > However, the program that I'm using seems to be having trouble connecting to the CUDA software. I've checked that the versions match (8.0). I'm at a loss for what else to do though, so any help you can provide would be appreciated. > > > > For reference, see attached my script and the error message in the slurm output. > > > > Many thanks, > > > > Andrew </div> </div> </body> </html>
