cuda.bindings.nvml.device_get_power_usage#

cuda.bindings.nvml.device_get_power_usage(intptr_t device) → unsigned int#

Retrieves power usage for this GPU in milliwatts and its associated circuitry (e.g. memory).

For Fermi ™️ or newer fully supported devices. On Fermi and Kepler GPUs the reading is accurate to within +/- 5% of current power draw. On Ampere (except GA100) or newer GPUs, the API returns power averaged over 1 sec interval. On GA100 and older architectures, instantaneous power is returned. See NVML_FI_DEV_POWER_AVERAGE and NVML_FI_DEV_POWER_INSTANT to query specific power values. It is only available if power management mode is supported. See nvmlDeviceGetPowerManagementMode.

Parameters:

device (intptr_t) – The identifier of the target device.

Returns:

Reference in which to return the power usage: information.

Return type:

unsigned int
