Parallel distributed objects' structure and their synchronization in an APPC environment

Abstract

Over a period of a few hours, every computer participating in a distributed system has many unused resources. If these resources can be combined, a large amount of computational power can be generated. This paper offers an object oriented approach for using this power and organizing an efficient work scheme, compatible with the efficiency of multiprocessor systems. A special structure for an object is described, with the help of which the work of a parallel concurrent object is ensured. Since a major problem in parallel systems is that of synchronization, synchronization methods and algorithms are offered to support the execution of parallel objects. The research and the proposed development are based on a common and popular application programming interface - APPC (Advanced Program to Program Communication). Experimental results show the efficiency of the approach.
