ρ Graph: Rendezvous ordering graph for Ada concurrent programs

  • 21 Accesses


In disciplined Ada software development and maintenance, an adequate and suitable graphical representation for concurrency is important. To describe rendezvous ordering, tasking and executing flow of tasks, ρ graph—Rendezvous Ordering Graph is presented in this paper. ρ graph is a kind of hierarchical oriented graph with nodes representing rendezvouses and edges showing ordering relations between rendezvouses as well as flow of tasks. It can be used in software understanding, design description and documentation.
