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

Compute mode

#nvidia-smi -g0 -c <mode number>

0 Default
1 Exclusive_Thread
2 Prohibited
3 Exclusive_Process
