    Service-oriented architectures are increasingly being used as the architectural style for creating large distributed computer applications. This paper examines the provision of visualization as a service that can be made available to application designers in order to combine with other services. We develop a three-layer architecture: a client layer which provides the user interface; a stateful Web... View full abstract»

    In order to be profitable, service providers must be able to undertake complex management tasks such as provisioning, deployment, execution and adaptation in an autonomic way. This paper introduces a framework, the semantically-enhanced resource allocator (SERA), aimed to facilitate service provider management, reducing costs and at the same time fulfilling the QoS agreed with the customers. The S... View full abstract»

    The integration of instruments with the grid promotes scientific and business collaboration by allowing shared access to rare and expensive instrumentation, regardless of its physical location. Instruments on the grid are virtualized resources similar to storage and computing devices, and can be part of composite services or workflows concurrently invoked by multiple users in such service-oriented...

    Cited by:  Papers (5)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (467 KB) | HTML iconHTML

    In scientific workflow systems, time related functionalities such as workflow scheduling and temporal verification normally require effective forecasting of activity durations due to the dynamic nature of underlying resources such as Web or grid services. However, most existing strategies cannot handle well the problems of limited sample size and frequent turning points which are typical for the d... View full abstract»

    Workflow technologies have become a major vehicle for the easy and efficient development of science applications. At the same time new computing environments such as the Cloud are now available. A challenge is to determine the right amount of resources to provision for an application. This paper introduces an algorithm named balanced time scheduling (BTS), which estimates the minimum number of vir... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1391 KB) | HTML iconHTML

    In this paper we describe the provenance system built into the distributed Martlet middleware. Due to both the need for scientific reproducibility, and to determine exactly what has happened with any given piece of analysis, it is necessary for this middleware to record detailed and structured provenance data in an easily query-able form. This is achieved through the use of integer clocks and dire... View full abstract»

    3-dimensional visualization is an integral part of satellite data processing and adds great value in terms of interpretation and effective presentation. 3D visualization requires large amount of data and compute power to map the data into underlying terrain model. Grid Technologies enable us to effectively harness the vast computational resources available at geographically separated data receptio... View full abstract»

    Soundness property has been defined as the minimal correctness requirement that every business workflow must meet. The property guarantees the absence of livelocks, deadlocks, and other anomalies that can be detected without exact domain knowledge. In this paper we extend the notion of soundness to grid workflows. In addition to discovering flaws in the control flow, our notion also captures incor... View full abstract»

    There are various issues that limit the development and deployment of new software solutions in cancer image analysis research. In this paper we discuss some of these and propose a framework design based on cloud computing concepts, Microsoft technologies, existing middleware and imaging toolkits. Furthermore, we address some of these issues by introducing collaborative visual tools for visual inp... View full abstract»

  • WOOL: A Workflow Programming Language

    Cited by:  Papers (1)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (180 KB) | HTML iconHTML

    Workflows offer scientists a simple but flexible programming model at a level of abstraction closer to the domain-specific activities that they seek to perform. However, languages for describing workflows tend to be highly complex, or specialized towards a particular domain, or both. WOOL is an abstract workflow language with human-readable syntax, intuitive semantics, and a powerful abstract type... View full abstract»

    Cited by:  Papers (6)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (259 KB) | HTML iconHTML

    The security models used in Grid systems today strongly bear the marks of their diverse origin. Historically retrofitted to the distributed systems they are designed to protect and control, the security model is usually limited in scope and applicability, and its implementation tailored towards a few specific deployment scenarios. A common approach towards even the "basic" elements such as authent... View full abstract»

    Many scientists maintain blogs and participate in online communities through their blogs and other scientists' blogs. This study used social network analysis methods to locate and describe online communities in science blogs. The structure of the science blogosphere was examined using links between blogs in blogrolls and in comments. By blogroll, the blogs are densely connected and cohesive subgro... View full abstract»

    Grid workflows can produce thousands of results that should be properly organised to enable further analysis. Typically results are stored on locations hard-coded in the workflow or in the components, limiting reusability. In this paper we present an approach to (re)organise the output files generated by a grid workflow in a distributed storage environment. We propose to perform a post-mortem mapp...

    Semantic inferencing and querying across large-scale RDF triple stores is notoriously slow. Our objective is to expedite this process by employing Google's MapReduce framework to implement scale-out distributed querying and reasoning. This approach requires RDF graphs to be decomposed into smaller units that are distributed across computational nodes. RDF Molecules appear to offer an ideal approac... View full abstract»
