GPU Profiler (wxWidgets + NVML)

A simple desktop application for Linux (XFCE/GNOME) to monitor NVIDIA GPU usage, memory, temperature, power, and running GPU processes in real time.
Built with C++, wxWidgets, CMake, and NVIDIA Management Library (NVML).

Features

• Real-time GPU Monitoring:
  • GPU name, utilization, memory usage, temperature, and power usage.
  • Timeline charts for memory, utilization, and temperature (like Task Manager).
  • Support monitoring multiple NVIDIA GPUs.
• Process List:
  • Shows all processes using the GPU (compute/graphics/both).
  • Efficiently updates with minimal flicker.
• Cross-Desktop:
  • Works on XFCE, GNOME, and other Linux desktops (uses GTK via wxWidgets).

Build & Run

Prerequisites

• Linux with NVIDIA GPU and proprietary driver
• libnvidia-ml-dev (NVML)
• wxWidgets 3.x (GTK)
• GCC (g++), CMake 3.10+
• Git (optional)

Install dependencies (Ubuntu/Debian)

sudo apt update
sudo apt install build-essential cmake libwxgtk3.0-gtk3-dev libnvidia-ml-dev

Build

git clone https://github.com/lehoai/NvidiaGpuProfiler.git
cd Todo
mkdir build && cd build
cmake ..
make

Run

./GPUProfiler

Technical Details

• wxWidgets for cross-platform GUI (uses GTK on Linux).
• NVML (libnvidia-ml-dev) for direct, robust GPU and process info.
• Efficient UI updates:
  • Uses Freeze()/Thaw() and only updates changed rows/cells in the process list to minimize flicker.
• Custom timeline charts for memory, utilization, and temperature, using wxGraphicsContext.

Notes

• Process names/paths are read from /proc/<pid>/cmdline.
• Requires NVIDIA proprietary driver and NVML support.
• SSH remote features are coming soon
