The aim of this work is to examine the suitability of graph algorithms for parallelism and to look for possible problems. For this purpose, a sequential graph algorithm was parallelised and the corrsponding performance change was rated. Further, the course of events of the parallel program were presented by an existing system for visualization. The algorithm to parallelise is implemented in a program of the Institute for Operating Systems and Computer networks of the University of Hildesheim. The program searches the components and periodicity classes of digraphs. The change in Performance obtained by parallelism measured with the help of extensive and adequate systematic test material. As parallel computer, the KSR1 of the Gesellschaft für wissenschaftliche Datenverarbeitung Göttingen was used.
