Installing from Source

Prerequisites

Before you can install PRISMS-PF, you will need to have some prerequisites installed on your machine. These include:

• Git (to clone the repository)
• A C++ compiler with C++20 support (we recommend GCC or Clang)
• CMake (version 3.13.4 or higher)
• LAPACK (for linear algebra operations)
• MPI (we recommend OpenMPI or MPICH)
• p4est (for adaptive octree meshing)
• VTK (for file I/O) [optional]
• Caliper (for profiling) [optional]
• deal.II (version 9.6 or higher)

• Linux You can install these prerequisites however you like. The first five are typically available on most OSes through your package manager. For example, on Ubuntu, you can install them with:

  sudo apt-get install git lsb-release git subversion wget bc libgmp-dev build-essential
  autoconf automake cmake libtool gfortran python3 libboost-all-dev zlib1g-dev openmpi-bin
  openmpi-common libopenmpi-dev libblas3 libblas-dev liblapack3 liblapack-dev
  libsuitesparse-dev

  To install p4est, you can follow these instructions:
• MacOS This is the content of tab 2
• Windows PRISMS-PF has no plans to support Windows. If you are on Windows, we recommend using a virtual machine or Windows Subsystem for Linux (WSL) to run a Linux environment. Please follow the Linux instructions if you use either of those options.
