Interested in the real-time scheduling mechanisms available in CPAL and their analysis? — download technical report here. The code of the experiments and the schedulability analysis for the FIFO scheduling policy is available on GitHub.

A fully compliant CPAL parser, along with a model-transformation (MT) framework has been released in open-source under AGPLv3.0 license by RealTime-at-Work, CNR (Italy) and University of Luxembourg. The source code is available on github.

The source code for the schedulability analysis of FIFO tasks with offsets, one of the scheduling model supported by CPAL, is available on github. The schedulability analysis itself has been published in this technical report.
