CCS aims at providing interoperability between autotuning frameworks and applications with auto-tuning needs. It does so by providing a C interface to describe autotuning problems and autotuners.
CCS has been greatly inspired by https://github.com/automl/ConfigSpace, and was first thought as a drop in replacement for the engine of ConfigSpace.
