PARCS (Parallel Asynchronous Recursive Control System) programming tools that allow unified add-on parallel extensions over traditional programming languages are described. The PARCS model is based on the conception of a control space, which is used to describe parallel interacting processes. Structurally, the control space consists of addressable “points” and “channels”. Executing modules are assigned to points and communicate through channels connecting points. Recursive embeddings of processes are allowed. The effective implementation of PARCS on cloud platforms Microsoft AZURE and Amazon EC2 is also presented.
