ARES is the main component of the Bayesian Large Scale Structure inference pipeline. The present version of the ARES framework is 2.1. Please consult the Release notes for an overview of the different improvements over the different versions.

ARES is written in C++14 and has been parallelized with OpenMP and MPI. It currently compiles with major compilers (gcc, intel, clang).
