    In object-oriented development of distributed computing system software, one of the important tasks is to cluster objects into modules for achieving high performance, which is heavily affected by intermodule communication and the degree of parallel execution of modules. In this paper, a clustering algorithm is presented based on reducing intermodule communication and increasing concurrency for mod... View full abstract»

    In the abstract modelling of distributed systems we may need methods to replace abstract behaviours by more concrete behaviours which are closer to implementation mechanisms. Furthermore, we may want these methods to preserve the correctness of such a replacement. This paper introduces an approach towards action refinement in which an abstract action is replaced by a concrete activity. This approa... View full abstract»

    A leader election algorithm based on the performance and the operation rate of nodes and links as proposed. The performance of the existing leader election algorithms should be improved because a distributed system pauses until a node becomes a unique leader among all nodes in the system. The pre-election algorithm that elects a provisional leader while the leader is executing is also introduced View full abstract»

    This paper discusses how object orientation in application design enables confidentiality aspects to be handled more easily than in conventional approaches. The idea, based on object fragmentation at design time, is to reduce processing in confidential objects; the more non confidential objects can be produced at design-time, the more application objects can be processed on untrusted shared comput...

    We propose two multicast routing algorithms. One is a delay-constrained multicast algorithm that finds a multicast tree between one source node and multiple destination nodes. The other is a dynamic multicast algorithm that allows multiple nodes to dynamically join or leave a multicast group during a session. The first algorithm, which provides multicasting and guaranteed QoS (Quality-of-Service) ... View full abstract»

    We study tracing garbage collection (GC) for a distributed shared memory (DSM) in order to provide persistence by reachability (PBR), in a large-scale distributed system. Within a general model of DSM, we specify a distributed tracing GC algorithm that scales, collects cycles, and is orthogonal to coherence. Its main features are: (i) piecewise collection of opportunistically-chosen subsets of the... View full abstract»
