In this talk, I present a new programming language designed for structured concurrency. The language is based on components which are organized in hierarchical and “pointer-free” structures. The components run concurrently and only interact via communication. With this model, hierarchical encapsulation, statefull interactions, race-free concurrency, flexible polymorphism and a simple memory management is enabled. The language is implemented by a native runtime system which allows the efficient execution of a huge number of light-weight processes. In a case study of traffic simulation, it has been demonstrated that the new language enables a more natural mapping to the program and also offers a higher performance compared to other sequential or con¬current simulations.
