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.
