Abstract
A group communication system (GCS), for use within a group of clustered computing nodes, provides a flexible group membership model. Flexible group members are defined generally as physical computing entities (such as computing nodes or other devices) or logical computing entities that take part in a distributed application. Such logical entities may include substantially any combination of processes, threads and callback functions. Logical entities that are members in the group may also be objects, such as files, that at least at some times during their existence have no active processes or threads. A single member may include multiple simultaneous processes.
