We present a contribution on dynamic load balancing for distributed and parallel object-oriented applications. We specially target peer-to-peer systems and their capability to distribute parallel computation. Using an algorithm for active-object load balancing, we simulate the balance of a parallel application over a peer-to-peer infrastructure. We tune the algorithm parameters in order to obta...

Cloud computing provides a robust infrastructure that can facilitate computing power as a utility service. All the virtualized services are made available to end users in a pay-as-you-go basis. Serving user requests using distributed network of Virtualized Data Centers is a challenging task as response time increases significantly without a proper load balancing strategy. As the parameters invo...

Numerous works has been done for load balancing of web servers in grid environment. Reason behinds popularity of grid environment is to allow accessing distributed resources which are located at remote locations. For effective utilization, load must be balanced among all resources. Importance of load balancing is discussed by distinguishing the system between without load balancing and with loa...

We give a distributed one pass streaming algorithm for graph sparsification. Besides producing a sparsifier, our algorithm maintains a hierarchy of UNION-FIND data structures in a distributed manner that efficiently support queries of strong connectivities between pairs of vertices. An important component of the algorithm is an implementation of UNION-FIND queries over an Active Distributed Has...

This paper describes a model for developing applications of active object-oriented databases based on three orthogonal concepts; methods, guards and actions and a tool which implements these ideas called MGA. MGA objects are active; they have guards which constrain the object's state, actions which maintain database integrity when the object's state changes and methods through which the object ...

Abstract Sub-seafloor hydrothermal processes along volcanically active plate boundaries are integral to the formation of seafloor massive sulfide deposits and oceanic iron cycling, yet nature their relationship is poorly understood. Here we apply isotope analysis minerals from Trans-Atlantic Geotraverse (TAG) mound underlying stockwork, 26°N Mid-Atlantic Ridge, trace inside an actively-forming ...

The problem of nding a suitable formal approach to describe on-going reasoning process has been open since the very beginning of AI. In this paper we argue that active logic might be a formalism useful in this context. Active logic is rst introduced, then we analyse resource limitations that constrain the space of possible practical realisations of such reasoners. Finally some steps towards cre...
