Installation

This guide walks you through building the project from source, including required dependencies and build steps.

Prerequisites

Before building, make sure the following dependencies are installed on your system:

  • CMake
  • LAPACK
  • MPI (tested with version 3.1)
  • FFTW with MPI support (tested with version 3.3.10)
  • Fortran compiler
  • Currently, only Intel Fortran compilers are supported

Environment Setup (Example)

On systems like Caltech HPC, you can load the required modules with:

module load fftw
module load intel-oneapi-compilers
module load openmpi

Alternatively, if you prefer Intel MPI:

module load fftw/3.3.10-oneapi-2023.2.1-7czoymn
module load intel-oneapi-compilers
module load intel-oneapi-mpi

Building the Project

cmake -B build
cmake --build build

Alternatively, you can use 

mkdir build
cd build
cmake ..
make

Build Configuration

  • Default build type: Release

  • Applies optimization flags: -ipo -O3

  • Debug build:
    To enable debugging symbols and backtraces:

cmake -B build -DCMAKE_BUILD_TYPE=Debug
