DESCRIPTION
       The  NVIDIA  System  Management Interface (nvidia-smi) program provides
       system state and diagnostic information for  the	 NVIDIA	 Tesla	Visual
       Computing  Systems.  It provides these data in either plain text or XML
       format, printed to stdout or optionally written	to  a  user  specified
       file.

OPTIONS
       -h, --help
	      Print usage information and exit.

       -x, --xml-format
	      Produce XML output. Unless an output file is specified using the
	      -f option, all data are output to stdout.

       -f filename
       --filename=filename
	      Log to the named file filename, rather than to stdout.

       -l, --loop-continuously
	      Probe continuously, outputting to stdout unless an  output  file
	      is  specified  using  the -f option. If an output file is speci‐
	      fied, it is updated on each loop iteration.

       -i sec
       --interval=sec
	      Probe once every sec  seconds  when  probing  continuously.  The
	      default and minimum interval is 1 second.

       -t unit-number
       --toggle-led=unit-number
	      Toggle the LED state (ON -> OFF or OFF -> ON) for unit unit-num‐
	      ber. The unit number of an NVIDIA Tesla Visual Computing	System
	      can be found in the log file. Each NVIDIA Tesla Visual Computing
	      System unit attached to a given system has a unique unit	number
	      within that system.

       -a, --all-gpus
	      Include  discrete	 GPUs  when listings and consider them for GPU
	      specific options if no GPU is specified  using  the  -g  option.
	      Discrete	GPUs are GPUs not installed in QuadroPlex and/or Tesla
	      computing systems.

       -d, --discrete-gpus
	      Include only discrete GPUs in listings and consider them	exclu‐
	      sively for GPU specific options if no GPU is specified using the
	      -g option.

       -L, --list-gpus
	      Print a list of installed GPUs and exit.	By  default,  discrete
	      GPUs  are	 not  listed. This behavior can be changed with the -a
	      and -d options.

       -g gpu-id
       --gpu=gpu-id
	      Specify the GPU to be  targeted  when  specifying	 GPU  specific
	      options,	such  as  --show-compute-mode-rules.   The appropriate
	      gpu-id identifier can be obtained using the -L option.

       -q, --query-gpu-info
	      Print information about a given GPU or set  of  GPUs,  including
	      the  product name, PCI ID, temperature, and ECC error counts. No
	      information about any Visial Computing Systems attached  to  the
	      host  is	listed.	 Unless the -g option is used to select a spe‐
	      cific GPU, information  for  a  set  of  GPUs  is	 reported.  By
	      default,	this  set  only	 includes GPUs installed in QuadroPlex
	      and/or Tesla Visual Computing Systems. The -a and -d options can
	      be used to change the set.

       -c ruleset
       --compute-mode-rules=ruleset
	      Set  the	compute	 mode  rules  to ruleset for the GPU specified
	      using the -g option.

	      ruleset may be one of the following:
		   0 - Normal mode
		   1 - COMPUTE exclusive mode (only  one  COMPUTE  context  is
	      allowed to run on the GPU)
		   2  -	 COMPUTE  prohibited  mode  (no	 COMPUTE  contexts are
	      allowed to run on the GPU)

       -s, --show-compute-mode-rules
	      Display the current compute mode ruleset for the	GPU  specified
	      using the -g option. If no GPU is chosen with the -g option, the
	      rules for all GPUs are shown.

       -e config
       --ecc-config=config
	      Set the ECC configuration to config for the GPU specified	 using
	      the  -g  option.	Changes take effect with the next system boot.
	      The -q option reports ECC error statistics if ECC	 is  supported
	      and enabled.

	      config may be one of the following:
		   0 - Disabled
		   1  -	 Enabled  (ECC	will be used for video memory and some
	      engines)

       -r, --report-ecc-config
	      Report both the current and future (after reboot) ECC configura‐
	      tions  for  the  GPU specified using the -g option. If no GPU is
	      chosen with the -g option, the configuration  for	 all  GPUs  is
	      reported.

       -p, --reset-persistent-ecc-error-counts
	      Reset  persistent	 ECC error count. If no GPU is chosen with the
	      -g option, the counts for all GPUs are reset.

       -v, --reset-volatile-ecc-error-counts
	      Reset volatile ECC error count. If no GPU is chosen with the  -g
	      option, the counts for all GPUs are reset.

       -P level
       --set-power-limit=level
	      Set  the	input  power consumption limit, that the system is not
	      allowed to exceed, to equal level in Watts.

       -F filename
       --fault-log=filename
	      Read fault records, log them to  the  file  named	 filename  and
	      clear the fault records.

EXAMPLES
       nvidia-smi
	      Probe once and log all relevant data to stdout.

       nvidia-smi -l
	      Probe continuously and log to stdout.

       nvidia-smi -x -f newfile
	      Probe once and log to the file newfile in XML format.

       nvidia-smi -g 0 -s
	      Report the current COMPUTE ruleset for GPU 0.
