* At a ''[[Fork–join model|fork]]'', the process creates one or more additional processes, indicated by a bar with one incoming path and two or more outgoing paths. 
* At a ''join'', two or more processes continue as a single process, indicated by a bar with several incoming paths and one outgoing path. All processes must complete before the single process continues.<ref name="Nakatsu2009" />
