What you get

  • A cockpit gauge for one NVIDIA card: live utilisation, video memory, temperature, clock, power draw and performance state, with rolling history charts and a warning when the card is being throttled. Name your TOPG server on the device or over USB and the HUD subscribes to its live feed over Wi-Fi, a second at a time. Save several machines and switch which one the gauge is watching.
  • TOPG is the free agent that feeds it. It is a small open source program you run on the machine the graphics card is in - download a build for Windows, Linux or macOS, compile it yourself, or run it in Docker. It reads the card the same way nvidia-smi does and streams the numbers to your device over your own network, once a second. Nothing leaves your network and there is no account to make. Download it from https://github.com/sukesh-ak/TOPG.

Features

  • A cockpit ring for GPU load, with the reading big enough to catch from across the room.
  • Video memory as a percentage, a used-of-total figure and a filling cell grid.
  • Temperature, core clock, power draw, memory-controller load, free VRAM and performance state.
  • A throttle warning that turns the temperature red when the card is being held back.
  • Rolling history charts for load and memory, and a bar history for video memory.
  • Live over a WebSocket to the free TOPG agent on the machine being watched - one second per update.
  • Save several machines and switch which one the gauge is watching, on the device or over USB.
  • Fills the glass on every supported panel, portrait or landscape, from 2.4 to 10.1 inches.

Set up on the device

Point the app at the machine you want to watch without typing on the screen: install it on your device, plug the device into this computer, enter the address below and press Send. That is the machine running the free TOPG agent - its address on your network, and the port the agent listens on (8080 unless you changed it). The device saves it and connects straight away; you can add more machines on the device itself and switch between them.
