 concept to use dynamic process creation and inter-process communication.

The system is based on earlier work by Will R. Stoye. The system allow dynamic creation of functional processes. Processes are stream processors, functions that transform an ingoing to an outgoing stream. Process scheduling is based on evaluation on demand. Inter-process communication

Inter-process communication

In computing, Inter-process communication is a set of methods for the exchange of data among multiple threads in one or more processes. Processes may be running on one or more computers connected by a network. IPC methods are divided into methods for message passing, synchronization, shared...

Message passing

Message passing in computer science is a form of communication used in parallel computing, object-oriented programming, and interprocess communication. In this model, processes or objects can send and receive messages to other processes...
