  • Beschreibung: CSSA (Computing System for Societies of Agents) is an interactive programming language for asynchronous multiprocessor systems. Computations are done by concurrently working sequential modules, called agents which implement objects of data and control abstractions. Communication is done by passing messages to acquainted agents. The receiving agent creates an instance of an operation capability referred to in the message. Since agents can be created during the computation and acquaintances can be transmitted in messages the heterarchical agent-net may dynamically change. The language described in volume B of the CSSA-documentation has been successfully implemented for a multiprocessor simulation system running on a general purpose computer. This system allows the execution of CSSA-applications on a wide range of simulated multicomputer configurations. The use of the system is described in volume C. This volume contains the documentation of the different system-components including program sceletons and complete source-listings. Portability problems are discussed in the description of the program development system which is realized in the Siemens BS2000 command language. The reader is expected to have a certain knowledge of this language. Compiler and runtime system are written in SIMULA using to a large degree the more sophisticated language concepts of SIMULA, such as CLASS SIMULATION, hierarchical class definitions, virtual attributes of classes and prefix blocks. Therefore extensive knowledge of the SIMULA language is necessary for reading this volume.
