Open Heterogeneous Computing in Actor Space

A number of e orts in heterogeneous computing involve the development of basic architecture independent communication primitives We present a new programming paradigm called ActorSpace which provides a new communication model based on destination patterns An actorspace is a computationally passive container of actors which acts as a context for matching patterns Patterns are matched against listed at tributes of actors and actorspaces that are visible in the actorspace Both visibility and attributes are dynamic Messages may be sent to one or all members of a group de ned by a pattern The paradigm provides powerful support for component based construc tion of heterogeneous scalable distributed applications In particular it supports open interfaces to servers and pattern directed access to software repositories
