NVIDIA System Management Interface -- v530.30.02

NVSMI provides monitoring information for Tesla and select Quadro devices.
The data is presented in either a plain text or an XML format, via stdout or a file.
NVSMI also provides several management operations for changing the device state.

Note that the functionality of NVSMI is exposed through the NVML C-based
library. See the NVIDIA developer website for more information about NVML.
Python wrappers to NVML are also available.  The output of NVSMI is
not guaranteed to be backwards compatible; NVML and the bindings are backwards
compatible.

                                Typically useful if a double bit ECC error has
                                occurred.
                                Reset operations are not guarenteed to work in

                                    of desired locked GPU clock speed in MHz.
                                    Setting this will supercede application clocks
                                    and take effect regardless if an app is running.

                                    of desired locked Memory clock speed in MHz.
                                    Input can also be a singular desired clock value

                                    applied after GPU reset. Note that, this limit is
                                    persistence across system reboots.    -rmcd --reset-memory-clocks-deferred
                                Resets the deferred Memory clocks applied.
    -ac   --applications-clocks= Specifies <memory,graphics> clocks as a
                                    pair (e.g. 2000,800) that defines GPU's
                                    speed in MHz while running applications on a GPU.
    -rac  --reset-applications-clocks
                                Resets the applications clocks to the default values.
    -pl   --power-limit=        Specifies maximum power management limit in watts.
    -cc   --cuda-clocks=        Overrides or restores default CUDA clocks.
