Zhuoan Jiao, Jasmin Wason, Wenbin Song, Fenglian Xu, Hakki Eres, Andy J Keane, Simon J Cox
2004 Lecture Notes in Computer Science  
As the Grid moves towards adopting a service-oriented architecture built on Web services, coupling between processes will rely on secure, reliable, and transacted messages and be supported by databases  ...  We have built a generic toolkit targeted at design engineers, which provides convenient methods to access a grid-enabled repository.  ...  The toolkit enables engineers to write scripts in a familiar language and archive them along with data produced at various stages of the design optimisation process to a grid-enabled database.  ...

Spelunking: Experiences using the DIVE System on CAVE-like Platforms [article]

Anthony Steed, Jesper Mortensen, Emmanuel Frécon
2001 ICAT-EGVE 2014 - International Conference on Artificial Reality and Telexistence and Eurographics Symposium on Virtual Environments  
Until recently, support for immersive systems has been limited to custom support for specific installations and the emphasis has been on broad support for desktop interfaces.  ...  Recently we have ported DIVE to the CAVElib™ environment† and this paper describes application programming support for immersive users and our experience in using wide-area distributed applications involving  ...  Furthermore through DIVE/TCL programmers can remotely access interface and plugin functionality on other clients and can use this to reconfigure clients as necessary.  ...

Modular Workflow Engine for Distributed Services using Lightweight Java Clients [article]

R.-M. Vetter, W. Lennartz, J.-V. Peetz
2009 arXiv   pre-print
The engine submits data to the clients and orchestrates their work by workflow descriptions from a central database.  ...  Only a Java runtime environment and the JAR files comprising the workflow client are needed. To connect all clients to the engine one open server port is sufficient.  ...  ACKNOWLEDGMENTS The authors would like to thank Yvonne Havertz from University of Cologne, Dr. Annette Kuhlmann from Shell Germany, and Dr. Detlef Billep from Fraunhofer Institute ENAS.  ...

ZENTURIO: A Grid Service-Based Tool for Optimising Parallel and Grid Applications

Radu Prodan, Thomas Fahringer
2004 Journal of Grid Computing  
Then we introduce a generic framework for solving NP-complete optimisation problems for parallel and Grid applications.  ...  In this paper we first comparatively present various issues from our transition to an Open Grid Services Infrastructure (OGSI)-compliant prototype.  ...  The objective function is the only problem dependent component of the framework that has to be separately supplied for each particular optimisation task.  ...

An Information Retrieval Prototype for Research and Teaching

Christa Womser-Hacker
2020 Zenodo  
The main issue of MIMOR is the exploitation of users' relevance feed-back in order to optimise the fusion of several retrieval engines or resources.  ...  It is used to gain further insights concerning the behaviour of informa-tion retrieval systems as well as for teaching in the field of Information Sci-ence.  ...  Since the Java™ class through which the components' functions are accessed has to be tailored to the individual component, the module object in RECOIN serves merely as a wrapper for the plug-in functions  ...

Optimising Java RMI Programs by Communication Restructuring [chapter]

Kwok Cheung Yeung, Paul H. J. Kelly
2003 Lecture Notes in Computer Science  
A remote server may also make RMI calls to another remote server on behalf of the client if necessary.  ...  We also discuss some of the challenges involved in maintaining program semantics, and show how the approach can be used for more ambitious optimisations in the future.  ...  Also, it cannot detect indirect data dependencies -for example, if the RMI call modifies a remote database which the client proceeds to access using another API, then that access will go unnoticed.  ...
