This repository documents the software stack and the experimental setup of the manuscript: Automatic Code Generation for High-Performance Discontinuous Galerkin Methods on Modern Architectures.

It provides the technical details of how the results of the manuscript were achieved, but reproduction might require adapting its scripts and configuration files to your computing environment.

In general the procedure is:

• Clone this repository recursively
• Run ./patch.sh
• Run ./build_{haswell,skylake}.sh
• Go into the individual subfolders of build/dune-codegen-paper and apply this procedure to produce a plot:
  • Run the execution script (like donkey.sbatch or skylake.sh) (watch out for requirements on the working directory...)
  • If there, run process.sh to distill the data
  • Copy the resulting csv files into the source and commit them through git-lfs
  • Run plot.py in a suitable env (say through run-in-dune-env) to generate pdfs.
