nvidia-pstate

A library and CLI utilities for managing performance states of NVIDIA GPUs.

Installation

Prerequirements

Linux

Make sure you have the proprietary NVIDIA driver and the package providing libnvidia-api.so installed.

• ArchLinux: nvidia-utils
• Debian: libnvidia-api1
• Ubuntu: libnvidia-gl-535 (?)

Windows

Make sure the NVIDIA driver is installed.

Installation

pip3 install nvidia_pstate

Usage (CLI)

# List available performance states (TODO: does not work right now, use nvidia-smi -q and count memory clocks)
nvidia-pstate -q

# Set performance state for specific GPU
nvidia-pstate -i 0 -ps 0

# Let driver decide which performance state GPU should use
nvidia-pstate -i 0 -ps 16

# Set performance state for specific GPUs
nvidia-pstate -i 0 1 3 4 -ps 0

# Set performance state for all GPUs
nvidia-pstate -ps 0

Usage (API)

from nvidia_pstate import set_pstate_low, set_pstate_high

set_pstate_low() # set pstate to "low" level (8 by default)
set_pstate_high() # set pstate to "high" level (16 by default)

# default values can be overrided using NVIDIA_PSTATE_LOW and NVIDIA_PSTATE_HIGH environment variables.
