Extending PVM with consistent cut capabilities application aspects and implementation strategies

Message passing libraries are now widely used to develop parallel and distributed applications. Despite different services are provided by the available packages, still little support is given for distributed consistent cut, a facility which constitutes the base for higher level services both at system level (e.g. distributed debugging and fault tolerance), and at the application level (e.g. distributed simulation). In this paper we discuss different strategies to integrate a consistent cut protocol in PVM system
