Disable or enable GPU
##Disable GPU, where xx is PCIe bus number from lspci
$sudo nvidia-smi -i 0000:xx:00.0 -pm 0
$sudo nvidia-smi drain -p 0000:xx:00.0 -m 1
## The device will still be visible with lspci after running the commands above.
#Enable GPU
$sudo nvidia-smi drain -p 0000:xx:00.0 -m 0
--gpus options
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[1]
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[2]
# nvidia-smi -g 0 --reset-ecc-errors=TYPE (0|VOLATILE or 1|AGGREGATE)
Reset GPU
# nvidia-smi -g 0 --gpu-reset
GPU mode
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.
Graphic mode
Compute mode
#nvidia-smi -g0 -c <mode number>
| number | Mode | Meaning |
|---|---|---|
0
|
Default
|
Default mode GPU can be shared with several jobs, |
1
|
Exclusive_Thread
|
Exclusive thread mode only is allowed to run one job, but in the same time, only one thread runs on exclusive thread mode GPU. |
2
|
Prohibited
|
prohibited mode GPU is not allowed to run job, |
3
|
Exclusive_Process
|
Exclusive process mode is allowed to run one job, but in the same time, only one process runs on exclusive process mode GPU. |
GPU parameter change
Enable or disable GPU's auto boost mode
$ sudo nvidia-smi --auto-boost-default=DISABLED
Set GPU clock speed
$ sudo nvidia-smi --applications-clocks=2505,875
