Abstract: We consider the System V operation over a set of Dijkstra semaphores as a formal system and prove its Turing completeness. In this way, we define place-transition nets with a novel, stepless semantics, which implement transition firing rules similar to those of Petri and Salwicki. Each transition represents a thread, repeating an operation over a set of semaphores, which specify transition's incident arcs. To represent an efficient Sleptsov-Salwicki firing rule, a generalized operation over a set of semaphores is introduced. This opens prospects for fast asynchronous hardware and software implementations for the corresponding graphical language of concurrent programming. [ABSTRACT FROM AUTHOR]
