Data Management

Description

Data Management is the most significant challenge to many user communities within EGEE. It also represents one of the main uses of e-infrastructure - the large scale computational analysis of large volumes of data. Many communities are having to develop new techniques and use new services to deal with the 'data deluge' coming from their research activities. Now that the e-infrastructure exists to store and analyse the data, the next challenge for many end-users is how to derive information and gain knowledge from the raw data to meet their research objectives.

The presentations cover two broad areas - the standards being used to provide consistent access to the data management services and the services that form the operational e-infrastructure. These presentations will include:

how standards from the Open Grid Forum (ByteIO, WSDAIR and RNS) are being used to navigate and access information stored in catalogues, such as the LFC or AMGA, so that these can be accessed from either Windows or Linux.

how an application community has been validating the operational effectiveness of the infrastructure (both its services and networking links) as part of their distributed data analysis.

how 3D graphical images of data sets can be analysed using the e-Infrastructure.

how distributed key storage services can be used to encrypt and store data using the existing e-infrastructure.

66. Grid Interoperation: SRM-SRB Development

Mr Wei-Long Ueng (Academia Sinica Grid Computing)

Grid Services exploiting and extending gLite middleware

Oral

Storage Resource Manager (SRM) is based on a common interface specification, which is a widely adopted interface to the storage management system of production grids currently. With the heterogeneity of the Grid, the best way to share data is to integrate data sources through SRM. In this project, the SRM services for SRB is developed, to make the popular SRB data grid system interoperable...

37. New Developments in the AMGA Metadata Catalogue

Dr Birger Koblitz (CERN-IT)

Grid Services exploiting and extending gLite middleware

Oral

We present an overview of the latest developments in the AMGA metadata catalogue that have been made available with the AMGA 1.9 release and take a look at the upcoming AMGA 2.0 production release. The most prominent new features include the more scalable backend, the WS-DAIR support and native SQL queries. To exemplify their value for the EGEE community existing use cases will be shown.

50. Standards-based Access to LFCs

Grid Services exploiting and extending gLite middleware

Oral

We present two web services that provide standards-based access to grid data registered in LCG File Catalogs. These services use gLite APIs to implement Open Grid Forum standards. The SNARL (Standards-based Naming for Accessing Resources in LFCs) service implements the Resource Namespace Service (RNS) specification while the SABLE (Standards-based Access to Bytes of LFC Entries) service...

167. Mounting the Grid into the UNIX and Windows File Systems

Emerging Technologies within the EGEE infrastructure

Oral

In our work, we mount the Grid directly into the UNIX and Windows environments. Specifically, we enable access to files registered in LCG File Catalogs (LFCs), the file catalog technology currently used in the EGEE Grid. We accomplish this by utilizing existing Open Grid Forum (OGF) standards-based technologies. By grafting the Grid onto a familiar file system infrastructure, we increase...
