A formal model of atomicity in asynchronous systems

  • Eike Best
  • Brian Randell


We propose a generalisation of occurrence graphs as a formal model of computational structure. The model is used to define the “atomic occurrence” of a program, to characterise “interference freeness” between programs, and to model error recovery in a decentralised system.
