AccessingGPGPUresourcesviagrid
• Exec script with docker command to access the GPU:docker run --device=/dev/nvidia0:/dev/nvidia0 \
--device=/dev/nvidia1:/dev/nvidia1 \
--device=/dev/nvidiactl:/dev/nvidiactl \
-v $WDIR:/home opencl_disvis /bin/sh \

disvis /home/O14250.pdb /home/Q9UT97.pdb /home/restrain
• The docker container was built directly on the site with cuda5.5 and is thus site-specific (hardware dependencies)
