GUIDE TO CONFIGURE THE MONOALG_3D ON A FEDORA 33 MACHINE

This guide provides instructions to configure the MonoAlg3D solver in a fresh instalation of Fedora 33 with all its features working.

1) Download and build a USB boot drive

Download the Fedora 33 ISO image:

Burn the ISO image in a USB device using the Rufus program (Windows) or any other program.

Install Fedora 33 in the target machine

Perform a system update:

$ sudo dnf update

Change the graphic mode to "GNOME over Xorg"

  • Close your current session
  • Click on your user
  • Click on the gear symbol and select the "GNOME over Xorg"
  • Begin your session again

Reboot your system

$ reboot

Install the GNOME-Tweak-Tools

$ sudo dnf install gnome-tweak-tool

Open the Gnome-Tweak-Tool

  • Disable animations to save memory
  • Disable the suspend screen when notebook is closed

2) Install RPMFusion

Add the packages to your system:

$ sudo dnf install https://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm https://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-$(rpm -E %fedora).noarch.rpm
$ sudo dnf update

Open the Gnome-Programs

  • Go to Program Repositories
  • Enable the RPMFusion repositories for NVIDIA
  • Update the repositories again
$ sudo dnf update
  • Reboot your system
$ reboot

3) Install the NVIDIA driver

Reboot your system

  • Enter your BIOS by pressing F12 (check your computer key)
  • Disable the Secure Boot
  • Save your changes and exit

Run the following commands

$ sudo dnf update
$ sudo dnf install akmod-nvidia
$ sudo dnf install xorg-x11-drv-nvidia-cuda

Wait around 5 to 8 minutes in order to the NVIDIA kernels get built

  • Check if the kernels are ready
$ modinfo -F version nvidia
  • This should return the version of the driver such as 465.27

Reboot your system

$ reboot

Check if the NVIDIA driver is correctly installed

  • Go to Settings > About
  • Your NVIDIA Graphics Card should appear below the Processor field.

4) Install CUDA libraries

Download the CUDA runfile for your operating system

$ cd ~; mkdir CUDA-Install; cd CUDA-Install
$ wget -nc https://developer.download.nvidia.com/compute/cuda/11.3.0/local_installers/cuda_11.3.0_465.19.01_linux.run

Install dependencies

$ sudo dnf install gcc-c++ mesa-libGLU-devel libX11-devel libXi-devel libXmu-devel libXcursor-devel libXrandr-devel
$ sudo dnf install freeglut freeglut-devel

Run the CUDA runfile

$ chmod +x cuda_11.3.0_465.19.01_linux.run
$ sudo ./cuda_11.3.0_465.19.01_linux.run

Configure the installation

  • Accept the terms
  • Disable the NVIDIA Driver installation
  • Enable the installation: CUDA Toolkit, CUDA Samples, CUDA Demo, CUDA Documentation
  • Install the package

Post installation steps

Log as root user

$ su -
  • If is the first time logging as root, you can set a password to the "root" user with:
$ sudo passwd root

Set the PATH and LD_LIBRARY_PATH by creating a shell configuration file for CUDA

cat << EOF > /etc/profile.d/cuda.sh
pathmunge /usr/local/cuda/bin before

if [ -z "${LD_LIBRARY_PATH}" ]; then
    LD_LIBRARY_PATH=/usr/local/cuda/lib64
else
    LD_LIBRARY_PATH=/usr/local/cuda/lib64:$LD_LIBRARY_PATH
fi

export PATH LD_LIBRARY_PATH
EOF

Logout and login again and check the variables

$ echo $PATH
$ echo $LD_LIBRARY_PATH

Test the CUDA library

$ cd /home/<username>/NVIDIA_CUDA-11.1_Samples/1_Utilities/deviceQuery
$ make
$ ./deviceQuery

5) Configure MonoAlg3D_C

Download remaining dependencies

$ sudo dnf install libXcursor-devel libXrandr-devel libXinerama-devel

If you stop here you already have a working MonoAlg3D binary executable in the /bin folder

[OPTIONAL] Install and configure MPI for batch simulations

Download OpenMPI

$ cd ~; make OpenMPI-Install; cd OpenMPI-Install
$ wget -nc https://download.open-mpi.org/release/open-mpi/v4.1/openmpi-4.1.1.tar.gz

Build OpenMPI

$ gunzip -c openmpi-4.1.1.tar.gz | tar xf -
$ cd openmpi-4.1.1
$ ./configure --prefix=/usr/local
$ sudo make all install
