Installing nvtop

Issue #68 of nvtop (a htop-like program for NVIDIA GPUs) notes RE: the apt package for Ubuntu 20.04, "Canonical ruined the package totally"

The solution is to install the package manually

• Dependencies are: CMake, ncurses, git

  sudo apt install cmake libncurses5-dev libncursesw5-dev git`

• nvtop build instructions are at the end of the README (I recommend putting it in ~/opt so cd ~/opt first)

  git clone https://github.com/Syllo/nvtop.git
  mkdir -p nvtop/build && cd nvtop/build
  cmake ..

  • I got the message Found NVML: /usr/local/cuda-11.2/include (found version "11") with no errors (on Ubuntu 20.04, CUDA 11.2) but if you get an error run this:

    # If it errors with "Could NOT find NVML (missing: NVML_INCLUDE_DIRS)"
    # try the following command instead, otherwise skip to the build with make.
    cmake .. -DNVML_RETRIEVE_HEADER_ONLINE=True

  then finish the installation with:

  make
  sudo make install

Now nvtop will be available on the command line!

• Note: for integrated Intel GPUs, sudo apt install intel-gpu-tools and then sudo intel_gpu_top will show GPU usage
