roctop

roctop is a small AMD ROCm GPU monitor. It shows GPU VRAM usage, utilization, type, temperature, fan, power, clocks, live system/GPU graphs, and GPU processes in a refreshing terminal UI.

Demo

The demo is rendered from synthetic data; process names, PIDs, users, and metrics are placeholders.

Features

• GPU overview: compact table for every ROCm GPU with GUID, standardized model, architecture, temperature, fan status, power draw, SCLK/MCLK clocks, VRAM usage, and utilization.
• Readable utilization bars: memory and GPU utilization are shown as inline bars with percentage labels and threshold colors, making idle, busy, and saturated devices easy to scan.
• Live history graphs: split graph panel tracks average host CPU, host memory, GPU utilization, and GPU memory usage over the recent refresh window.
• Process visibility: process table shows GPU index, PID, user, GPU memory, GPU memory percent, host CPU/memory percent, elapsed runtime, and full wrapped command lines.
• Interactive process navigation: move through processes with j/k or arrow keys, page through long lists, toggle process tree view, keep the selected process visible across refreshes, and sort by GPU, memory, CPU, PID, user, time, or command.
• Inspect and help popups: i inspects the selected process using the current snapshot and /proc, while ? opens an in-app keybinding reference. Both popups support arrow keys and h/j/k/l navigation.
• Safe process actions: x opens a high-contrast confirmation menu with Cancel, SIGTERM, and SIGKILL choices, plus status messages for missing processes, permission errors, and other failures.
• Robust data collection: combines rocm-smi GPU snapshots, amd-smi process process memory data, and ps process metadata, with fallbacks when process-specific data is missing or malformed.
• Script-friendly modes: --once renders a single terminal snapshot, --json prints normalized snapshot data, and --interval controls live refresh cadence.

Install

roctop expects ROCm command-line tools on PATH: rocm-smi is required, and amd-smi is used when available for richer per-process memory data.

From PyPI:

pip install roctop

Build from source:

git clone https://github.com/nrhevu/roctop.git
cd roctop
