Treffer: A Component Language for Structured Parallel Programming.

Current programming languages are still underdeveloped for the con struction of well-structured concurrent software systems. They typically impose many unnecessary and unacceptable compromises and/or workarounds due to a multiplicity of different suboptimal concepts. With regard to object-orientation, one can identify references, methods and inheritance as such inappropriate constructs. To overcome this unfavourable situation, we have designed and implemented a substantially new programming language which integrates a general component notion. Three fundamental relations govern components in this language: (1) hierarchical composition, (2) symmetric connections with a dual concept of offered and required interfaces and, (3) communication-based inter actions. With the use of various examples, the advantage of the new component language is demonstrated in this paper. [ABSTRACT FROM AUTHOR]
