Portable implementation of a computation kernel for the N-body problem with Kokkos

This repository contains the source code from an internship which aimed at exploring Kokkos (more details here).

• ./img: contains images of the plot figures.
• ./results: contains .txt result files from experiments.
• ./src: contains main .cpp source files.
• ./include: contains main header files (including kernel definitions).
• ./guix-tools: contains guix essential setup (channel file + manifests).
• ./scripts: contains experiment batch scripts + python plot script.
• ./org: contains main org source files.
• ./biblio: contains main references.

• List the dependencies:
  • ScalFMM (for cpp_tools) which requires Custom BLAS and FFT implementations.
  • xsimd (part of the xtensor-stack)
  • Kokkos
• We strongly encourage to use Guix. Here are the channels that we use (to update the ~/.config/guix/channels.scm file):
  • guix-hpc
  • guix-hpc-non-free
  • nonguix

• Kokkos programming guide
• API references:
  • API: Core
  • API: SIMD
• Old Kokkos Lectures
