Grid Query Optimisation in the Data Grid Query Optimisation Task - WP2, European DataGRID Project
Our aim is to realise an agent-based Grid simulator for studying "Grid Query Optimisation Strategies", as partially described in [SSS+01]. The purposes of this document are the following: • To identify some HEP use cases and, based on these use cases and requirements, to identify some user-level and Grid-level query optimisation opportunities. • To define an architecture for the simulator, in w...
متن کاملA Grid-Enabled Problem Solving Environment (PSE) for Design Optimisation within Matlab
The process of design search and optimisation using Computational Fluid Dynamics (CFD) is computationally and data intensive, a problem well-suited to Grid computing. The Geodise toolkit is a suite of Grid-enabled design optimisation and search tools within the Matlab environment. The use of these tools by the engineer is facilitated by intelligent design advisers targeted initially at CFD. The...
متن کاملSimulation of Dynamic Grid Replication Strategies in OptorSim
Computational Grids normally deal with large computationally intensive problems on small data sets. In contrast, Data Grids mostly deal with large computational problems that in turn require evaluating and mining large amounts of data. Replication is regarded as one of the major optimisation techniques for providing fast data access. Within this paper, several replication algorithms are studied...
متن کاملGrid Services in Action: Grid Enabled Optimisation and Design Search
We are developing a Grid Enabled Optimisation and Design Search system (GEODISE). It offers grid-based access to a state-of-the-art collection of optimisation and design search tools, industrial strength analysis codes, and distributed computing and data resources.
متن کاملUK Grid Simulation with OptorSim
As the computational and data handling requirements of large scientific collaborations grow, Grid computing is rapidly emerging as a feasible solution to these requirements. Optimising the use of Grid resources is crucial, and to evaluate potential optimisation strategies it is important to simulate them as realistically as possible before they are used on real Grids. We have developed the Grid...
