without nvidia-container-toolkit, [[docker]] with --gpus options makes following error
docker: Error response from daemon: could not select device driver "" with capabilities: --gpus options
nvidia-container-toolkit package will solve the issue
sudo apt-get update && sudo apt-get install -y nvidia-container-toolkit
 
== Turn on / off ECC<ref>https://thelinuxcluster.com/2013/07/24/turning-off-and-on-ecc-ram-for-nvidia-gp-gpu-cards/</ref> ==
To Turn off the ECC RAM
# nvidia-smi -g 0 --ecc-config=0
(repeat with -g x for each GPU ID)
To Turn back on ECC RAM
# nvidia-smi -g 0 --ecc-config=1
(repeat with -g x for each GPU ID)
To Reset ECC error<ref>https://developer.download.nvidia.com/compute/DCGM/docs/nvidia-smi-367.38.pdf</ref>
# nvidia-smi -g 0 --reset-ecc-errors=TYPE (0|VOLATILE or 1|AGGREGATE)
 
== Reset GPU ==
# nvidia-smi -g 0 --gpu-reset


== GPU mode ==
* [https://wiki.hpcmate.com Nvdia-smi tips and tricks]
The mode of the GPU is established directly at power-on, from settings stored in the GPU’s non-volatile memory.


gpumodeswitch changes the mode of the GPU by updating the GPU’s non-volatile memory settings.

Compute mode is a configuration that is optimized for high-performance computing (HPC) applications, Compute mode can cause compatibility problems with OS and hypervisors when the GPU is used primarily as a graphics device.
