We present the first end-to-end modeling and compilation flow to parallelize hard real-time control applications while fully guaranteeing the respect of real-time requirements on off-the-shelf hardware. It scales to thousands of dataflow nodes and has been validated on two production avionics applications. Unlike classical optimizing compilation, it takes as input non-functional requirements (real time, resource limits). To enforce these requirements, the compiler follows a static resource allocation strategy, from coarse-grain tasks communicating over an interconnection network all the way to individual variables and memory accesses. It controls timing interferences resulting from mapping decisions in a precise, safe, and scalable way.
