| The map above shows current traffic flows and traffic patterns across GLORIAD - as measured in Chicago. In the map, triangles show source of traffic; inverted trianges, destination. Sites connected by arcs are the heavist current consumers. Colors indicate network protocols and can be discovered by the listing of top users at the right. The small charts show traffic volume by application during the last two hours. Clicking on any of them takes you to a larger display. | ||
Project: Gridlab
Description: The GridLab project is a Grid application toolkit and testbed funded by the European Commission under the Fifth Framework Programme of the Information Society Technology, contract number IST-2001-32133. The GridLab project is grounded by two principles, (i) the co-development of infrastructure with real applications and user communities, leading to working scenarios, and (ii) dynamic use of grids, with self-aware simulations adapting to their changing environment. Key objectives include: Design and develop a Grid Application Toolkit (GAT), to provide core, easy to use functionality through a carefully constructed set of generic APIs for both simulation codes and Grid software. The GAT will contain independent modules for handling many different aspects of Grid programming, including simulation, performance and grid monitoring, resource brokering and selecting, performance prediction, interaction with information servers, security, notification, collaboration, data handling, remote visualization, and remote application steering. Simultaneously enhance real applications for the Grid, implementing new dynamic simulation scenarios using the GAT. Both Cactus and Triana will be extended to integrate and exploit GAT elements, making Grid Computing easily exploitable by a wide range of applications. Our simulation driven, compute intensive applications are fundamentally different from the highly data driven applications in many other Grid projects (e.g., DataGrid, GriPhyN, EuroGrid). Develop and test Grid infrastructure/applications on real testbeds, constructed by linking heterogeneous collections of supercomputers and other resources spanning Europe and the USA, using and extending existing testbeds. Interoperability with different testbeds will be ensured by also using production testbeds in the USA, driving international high speed network connectivity. Testing will be carried out by the project and by several large, closely related user communities, including an EU Astrophysics Network, and various multidisciplinary US funded collaborations.
