Requirements

AthenaK is designed to use as few external libraries as possible, enabling so-called "hermetic builds". The minimum set of requirements to build AthenaK on an x86 processor are:

• Kokkos Core library (can be cloned automatically with the source code)
• cmake (version 3.0 or later)
• C++17 (or later) compliant compiler

Additional, optional requirements include:

• MPI (for distributed memory parallelism on CPUs or GPUs)
• CUDA toolkit (for NVIDIA GPUs) and CUDA-aware MPI (if running on multiple GPUs)
