The actor computation model is another important topic: it is a powerful, expressive model of concurrent computation. This thesis is motivated by the need for an actor garbage collector for a distributed real-time system under development by the Real-Time Systems Group at Virginia Tech. It is shown that traditional garbage collectors—even those that operate on computational objects—are not sufficient for actors. Three algorithms, with varying degrees of efficiency, are presented as solutions to the actor garbage collection problem. The correctness and execution complexity of the algorithms is derived. Implementation methods are explored, and directions for future research are proposed.ix, 77 leavesBTDapplication/pdfenIn CopyrightLD5655.V855 1989.N447Electronic data processing -- Distributed processingParallel processing (Electronic computers)Thesishttp://scholar.lib.vt.edu/theses/available/etd-06102012-040603/
