    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»

    Publication Year: 2009, Page(s): 2
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (146 KB)

    Summary form only given. This talk (modestly) attend to address challenges and opportunities ahead of us for making parallel programming as efficient, as productive, as effective as possible, on both Multi-cores and large-scale infrastructures such as Grids and Clouds. We draw on our experience at simplifying the programming of applications that are distributed on local area network (LAN), on clus... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (163 KB)

    Summary form only given. Online storage and content distribution systems within the "cloud" of the Internet have provided a wide variety of services ranging from file sharing, software downloads, to stored or live video streaming, to a large community. With the increasing popularity of such systems, however, server and bandwidth costs have become prohibitively expensive, as files are hosted in eit... View full abstract»

    Cited by:  Papers (4)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (626 KB) | HTML iconHTML

    To address coordination and complexity issues, we formulate a grid task allocation problem as a bargaining based self-adaptive auction and propose the BarSAA grid task-bundle allocation algorithm. During the auction, prices are iteratively negotiated and dynamically adjusted until market equilibrium is reached. The BarSAA algorithm features decentralized bidding decision making in a heterogeneous ... View full abstract»

  • Scheduling Strategies for Cycle Scavenging in Multicluster Grid Systems

    The use of today's multicluster grids exhibits periods of submission bursts with periods of normal use and even of idleness. To avoid resource contention, many users employ observational scheduling, that is, they postpone the submission of relatively low-priority jobs until a cluster becomes (largely) idle. However, observational scheduling leads to resource contention when several such users crow... View full abstract»

    We describe our experiences from implementing and integrating a new job scheduling algorithm in the gLite Grid middleware and present experimental results that compare it to the existing gLite scheduling algorithms. It is the first time that gLite scheduling algorithms are put under test and compared with a new algorithm under the same conditions. We describe the problems that were encountered and...

    In the last few years, highly distributed, heterogeneous and dynamic environments have become usual contexts for scientific and business domains. In this work, we consider query scheduling over a grid-enabled distributed database, where the data may be partially or totally replicated into the component sites. Although there have been some previous proposals for query scheduling in distributed data... View full abstract»

    Many load balancing strategies have been proposed for distributed hash tables, like Pastry. These strategies assume that hash functions spread even skewed key distributions almost evenly over the ID space. They neglect the problem that many applications produce data with common keys (multi-sets) that entail hash collisions and therewith load imbalance concerning query and storage load. A second dr...

    This paper presents ldquoSelf-Chordrdquo, a bio-inspired P2P algorithm that can be profitably adopted to build the information service of distributed systems, in particular Computational Grids and Clouds. Self-Chord inherits the ability of Chord-like structured systems for the construction and maintenance of an overlay of peers, but features enhanced functionalities deriving from the activity of a...

    Efficient and effective full-text retrieval in unstructured peer-to-peer networks remains a challenge in the research community. First, it is difficult, if not impossible, for unstructured P2P search protocols to effectively locate items with guaranteed recall rate. Second, existing schemes to improve search successful rate often rely on replicating a large number of item replicas across the wide ... View full abstract»

    Current implementations of real-time collaborative applications rely on a dedicated infrastructure to carry out all synchronizing and communication functions, and require all end nodes to communicate directly with and through the central server. In this paper, we investigate an architecture, in which the most resource intensive functionality of continuous communication among collaborators to disse... View full abstract»

    In order to meet the increasing demands of present and upcoming data-intensive computer applications, there has been a major shift in the disk subsystem, which now consists of more disks with higher storage capacities and higher rotational speeds. These have made the disk subsystem a major consumer of power, making disk power management an important issue. People have considered the option of spin... View full abstract»

    Green computing is a new paradigm of designing the computer system which considers not only the processing performance but also the energy efficiency. Power management is one of the approaches in green computing to reduce the power consumption in distributed computing system. In this paper, we first propose an optimal power management (OPM) used by a batch scheduler in a server farm. This OPM obse... View full abstract»
