SSMI - Simplified NVIDIA System Management Interface Tool

ssmi is a lightweight command-line tool designed to provide a simplified version of the output from the NVIDIA System Management Interface (nvidia-smi). It focuses on displaying GPU and process details more concisely, offering a streamlined overview for quick assessments.

Features

• Display GPU details, including performance, temperature, power usage, memory usage, and utilization metrics.
• Display process details, listing each process utilizing the GPU, including process ID, type, name, and memory usage.
• Filter output to show only GPU details, only process details, or both.

Installation

There are two options for installation

Pip

pip install ssmi-py

Source

git clone https://github.com/simplified-nvidia-smi/ssmi-py
cd ssmi-py
sudo make install

This will install ssmi to /usr/bin and its man page to the appropriate system directories.

Usage

Run ssmi without any arguments to display both GPU details and process information.

ssmi

To display only GPU details:

ssmi -g

To display only process details:

ssmi -p

For more information and options, use the help flag:

ssmi -h
