Repository content

• sched contains schedulers compatible with Batsim 5 called External Decision Components (EDCs)
• input contains Batsim inputs: a SimGrid platform and a Batsim workload
• flake.nix contains reproducible debuggable Nix environments into which the simulations and the analysis can be run
• run-simus.sh is a simple script to run several Batsim instances in sequence
• run-rmarkdown-notebook.R is a simple script to render a Rmarkdown notebook

Prerequisites

• Nix installed: https://nixos.org/download/
• Flakes enabled in your Nix setup: https://nixos.wiki/wiki/Flakes#Other_Distros.2C_without_Home-Manager
• Enable the batuto binary cache if you do not want to recompile heavy deps: https://app.cachix.org/cache/battuto#pull

Run simulations and visualize results

nix develop .#simulation --command ./run-simus.sh

This should populate a simu-out directory, where each directory is a simulation output.

Analyze and visualize results

nix develop .#r-notebook --command Rscript run-rmarkdown-notebook.R ./simulation-output-analysis.Rmd

This should create/update a simulation-output-analysis.html file, that you can open with a web browser.
