    Computing is being transformed to a model consisting of services that are commoditised and delivered in a manner similar to utilities such as water, electricity, gas, and telephony. In such a model, users access services based on their requirements without regard to where the services are hosted. Several computing paradigms have promised to deliver this utility computing vision and they include Gr... View full abstract»

    Parallel TCP, which opens multiple TCP connections over a single direct path, and Multi-Pathing, which concurrently uses multiple disjointed paths to transfer data, have both been proved to be effective methods to improve end-to-end throughput. How much throughput can we ultimately achieve between a source and a destination if we use multiple overlay paths and open multiple TCP connections on each... View full abstract»

    The exchanged hypercube is an interconnection network which is obtained by systemically removing some links from a binary hypercube. In parallel systems, load balancing is a very important factor which can affect the performance of the whole system. So distributing tasks evenly on processors is essential for multiprocessor computing systems. Based on the classical DE-based algorithm, in this paper... View full abstract»

    GridDEV is a DEVS-based platform for evaluation of service grid. Through the analysis of SOA, we characterize important features of service grid and select four components as the base of grid modeling. With DSDEVS, this paper models the basic components selected, as well as the relationships between them. As a result, the model fully formalizes the grid system;hence facilitates the design and opti... View full abstract»

    Grid scheduling is one of the most crucial issue in a grid environment because it strongly affects the performance of the whole system. Taking into account that the issue of allocating jobs on resources is a combinatorial optimization problem, a NP-complete problem, several heuristics have been proposed to provide good performance. In this paper, the proposed approach considers a stochastic optimi... View full abstract»

    The problem of scheduling task graph which is represented by DAG (directed acyclic graph) in heterogeneous environment is not a new problem. However, up to now nearly all of the heuristics use forward planning methods. This paper introduces novel backward planning (BWP) procedure in this field. Quite different from forward planning methods, BWP always delays the tasks' starttime as late as possibl... View full abstract»

    In the Database-As-a-Service (DAS) paradigm, data owners outsource their data to the third-party service provider. Since the service provider is untrusted, the data should be encrypted before outsourced. Various approaches have been proposed to query on encrypted data, among which bucket based method is effective. However, previous researches just look at the data distribution with respect to a gi...

    The data-intensive workflow in scientific and enterprise grids has gained popularity in recent times. Data-intensive workflow needs to access, process and transfer large datasets that may each be replicated on different data hosts. Because of the large data sets, the execution time is bounded by the cost of data transfer. Minimizing the time of transferring these datasets to the computational reso... View full abstract»
