The interface layout selection has been updated to support the interface option. The interface option stores which data that needs to be plotted for each devices. The plot drawing code now supports the reverse plotting option. The interface uses the ring buffer, the updated version of the layout computation and plots the data specified by the interface options.
NVTOP
What is NVTOP?
Nvtop stands for NVidia TOP, a (h)top like task monitor for NVIDIA GPUs. It can handle multiple GPUs and print information about them in a htop familiar way.
Because a picture is worth a thousand words:

NVTOP Options and Interactive Commands
NVTOP comes with a manpage!
man nvtop
For quick command line arguments help
nvtop -h
nvtop --help
GPU Support
The NVML library does not support some of the queries for GPUs coming before the Kepler microarchitecture. Anything starting at GeForce 600, GeForce 800M and successor should work fine. For more information about supported GPUs please take a look at the NVML documentation.
Build
Two libraries are required:
- The NVIDIA Management Library (NVML) which comes with the GPU driver.
- This queries the GPU for information.
- The ncurses library driving the user interface.
- This makes the screen look beautiful.
Distribution Specific Installation Process
Ubuntu / Debian
Ubuntu disco (19.04) / Debian buster (stable)
-
sudo apt install nvtop
Older
- NVIDIA drivers (see Ubuntu Wiki or Ubuntu PPA or Debian Wiki)
- CMake, ncurses and git
sudo apt install cmake libncurses5-dev libncursesw5-dev git - NVTOP
- Follow the NVTOP Build
Fedora / RedHat / CentOS
- NVIDIA drivers, CUDA required for nvml libraries (see RPM Fusion)
- CMake, ncurses and git
sudo dnf install cmake ncurses-devel git - NVTOP
- Follow the NVTOP Build
OpenSUSE
- NVIDIA drivers (see SUSE Support Database)
- CMake, ncurses and git
sudo zypper install cmake ncurses-devel git - NVTOP
- Follow the NVTOP Build
Arch Linux
-
sudo pacman -S nvtop
Gentoo
-
sudo layman -a guru && sudo emerge -av nvtop
NVTOP Build
git clone https://github.com/Syllo/nvtop.git
mkdir -p nvtop/build && cd nvtop/build
cmake ..
make
make install # You may need sufficient permission for that (root)
If you use conda as environment manager and encounter an error while building nvtop, try conda deactivate before invoking cmake.
The build system supports multiple build type (e.g. -DCMAKE_BUILD_TYPE=RelWithDebInfo):
- Release: Binary without debug information
- RelWithDebInfo: Binary with debug information
- Debug: Compile with warning flags and address/undefined sanitizers enabled (for development purposes)
Troubleshoot
- The plot looks bad:
- Verify that you installed the wide character version of the NCurses library (libncursesw5-dev for Debian / Ubuntu), clean the build directory and restart the build process.
- Putty: Tell putty not to lie about its capabilities (
