    The computer science discipline, especially in large scale distributed systems like grids and P2P systems and in high performance computing areas, tends to address issues related to increasingly complex systems, gathering thousands to millions of non trivial components. Theoretical analysis, simulation and even emulation are reaching their limits. Like in other scientific disciplines such as physi... View full abstract»

    P2P storage systems must protect data against temporary unavailability and the effects of churn in order to become platforms for safe storage. This paper evaluates and compares redundancy techniques for P2P storage according to availability, accessibility, and maintainability using traces and theoretical results. View full abstract»

    Shared machines in opportunistic grids typically have large quantities of unused disk space. These resources could be used to store application and checkpointing data when the machines are idle, allowing those machines to share not only computational cycles, but also disk space. In this paper, we present the design and implementation of OppStore, a middleware that provides reliable distributed dat... View full abstract»

  • Cooperative Caching for Grid Based DataWarehouses

    Publication Year: 2007, Page(s):31 - 38
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (250 KB) | HTML iconHTML

    In this paper we propose a grid-based OLAP application which distributes query computation across an enterprise grid. Our application follows a two-tiered process for answering queries based on sharing cached OLAP data between the users at the local grid site, and using grid scheduling approaches to execute the remaining parts of a query amongst a distributed set of OLAP servers. A new technique f... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (237 KB) | HTML iconHTML

    Scientific applications often involve computation intensive workflows and may generate large amount of derived data. In this paper we consider a life cycle, which starts when the data is first generated, and tracks its progress through replication, distribution, deletion and possible re-computation. We describe the design and implementation of an infrastructure, called active data, which combines ... View full abstract»

    Interactive image processing is an important requirement in many industrial applications, such as the inspection of industrial parts within a manufacturing environment, or the processing of images from surveillance cameras. Being able to achieve this quickly and accurately is often essential for the success of such industrial applications. A service-based approach that autonomously launches Image ...

  • BBCLB: A Bulletin-Board based Cooperative Load Balance Strategy for Service Grid

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1163 KB) | HTML iconHTML

    Although many efforts have been put on the load balance in network and job scheduling systems, most of them, however, can not be applied in the service grid environment directly since they are often designed for a homogeneous system with limited scalability. It is still a challenge problem to balance the load among service grid nodes which are often highly dynamic, heterogeneous and linked by wide... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (453 KB) | HTML iconHTML

    Applications that span multiple virtual organizations (VOs) are of great interest to the eScience community. However, recent attempts to execute large-scale parameter sweep applications (PSAs) with the Nimrod/G tool have exposed problems in the areas of fault tolerance, data storage and trust management. In response, we have implemented a task-splitting approach, which breaks up large PSAs into a ... View full abstract»

  • An On-line Algorithm for Fair-Share Node Allocations in a Cluster

    Proportional (fair) share schedulers are designed to provide applications with predefined portions of system resources. Single node operating systems use context-switch (preemption) to dynamically allocate the CPU(s) to running processes. This paper presents an online algorithm for proportional share allocations of nodes in a cluster, in a fashion that resembles a single-node system. The algorithm... View full abstract»

    Process migration is essential for runtime load balancing. In Grid and shared networked environments, load imbalance is not only caused by the dynamic nature of underlying applications, but also by the fluctuation of resource availability. In a shared environment, tasks need to be rescheduled frequently to adapt the variation of resources availability. Unlike conventional task scheduling, dynamic ... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (293 KB) | HTML iconHTML

    This paper presents a method to optimize the timeout value of computing jobs. It relies on a model of the job execution time that considers the job management system latency through a random variable. It also takes into account a proportion of outliers to model either reliable clusters or production grids characterized by faults causing jobs loss. Job management systems are first studied consideri... View full abstract»

  • A Hybrid Linear Programming and Evolutionary Algorithm based Approach for On-line Resource Matching in Grid Environments

    Publication Year: 2007, Page(s):108 - 118
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (166 KB) | HTML iconHTML

    We describe a hybrid linear programming (LP) and evolutionary algorithm (EA) based resource matcher suitable for heterogeneous grid environments. The hybrid matcher adopts the iterative approach of the EA methods to perform a goal oriented search over the solution space and, within each iteration, uses the LP method to solve a partial resource matching problem. By judiciously controlling the parti... View full abstract»
