Distributed program execution control based on application global states monitoring in PEGASUS DA framework

Abstract

This paper presents control implementation methods for an original distributed program design framework PEGASUS DA (Program Execution Governed by Asynchronous SUpervision of States in Distributed Applications) which provides automated design of distributed program execution control based on program global states monitoring. The framework includes a built in support for handling local and global application states as well as automatic construction and use of strongly consistent application global states for program execution control. In particular, the paper presents methods used to implement distributed program control inside the PEGASUS DA framework run on clusters of contemporary multicore processors based on multithreading. The program design method is illustrated on a distributed multithreaded application executed with load balancing in a multicore system. © 2014 Springer-Verlag.
