106. An efficient method for fine-grained access authorization in distributed (Grid) storage systemsAndreas Peters (CERN)01/03/2006, 18:30Poster sessionPoster contributionThe ARDA group has developed an efficient method for fine-grained access authorization in distributed (Grid) storage systems. Client applications obtain "access tokens" from an organization's file catalogue upon execution of a file name resolution request. Whenever a client application tries to access the requested files, the token is transparently passed to the target storage ...

Dr Antonio Calanducci (INFN Sez. Catania - Italy), Dr Giuseppe La Rocca (INFN Sez. Catania - Italy)01/03/2006, 18:30Demo sessionDemo contributionCreated with the goal of providing an infrastructure for training and dissemination, GILDA revealed itself also as a cute entry point for those communities, often without any experience of distributed computing, desired to test whether or not their applications would receive an added value from the grid. The wide range of applications supported, shows also as a single testbed can serve...

Mr Juha HERRALA (CERN)01/03/2006, 18:30Poster sessionPoster contributionThe CMS Dashboard project aims to provide a single entry point to the monitoring data collected from the CMS distributed computing system. The monitoring information collected in the CMS dashboard allows to follow the processing of the CMS jobs on the LCG, EGEE and OSG grid infrastructures. The Dashboard supports tracing of the job execution failures on the Grid and erros due to problems...

Andrew Maier (CERN)01/03/2006, 18:30Demo sessionDemo contributionThe ARDA-LHCb prototype activity is focusing on the GANGA system (a joint ATLAS-LHCb project). The main idea behind GANGA is that the physicists should have a simple interface to their analysis programs. GANGA allows preparing the application, to organize the submission and gather results via a clean Python API. The details needed to submit a job on the Grid (like special configuration...

Prof. Peter Kacsuk (MTA SZTAKI)01/03/2006, 18:30Demo sessionDemo contributionThe P-GRADE portal plays more and more important role in the EGEE community. After its successful demos in the previous EGEE conferences (Athens and Pisa) the representatives of several EGEE VOs have approached us with the request to support their users by the P-GRADE portal that is already the official portal of two EGEE VOs: VOCE (Virtual Organization Central Europe) and HunGrid...

Mr John Walk (RAL)01/03/2006, 18:30Poster sessionPoster contributionIn order to make use of the resources of a grid, to submit a job or query information for example, a user must contact a service that provides the capability, usually via a URL. Grid services themselves must often contact other services to do their work. In order to locate services, some kind of dynamic service directory is required and there exist several grid information systems, such...

Mr Dashamir Hoxha (Institute of Informatics and Applied Informatics (INIMA), Tirana, Albania)01/03/2006, 18:30Poster sessionPoster contributionThis is a web application that serves as a front-end to the database that keeps information about the grid sites (clusters), their admins, email and phone contacts, other contact people, site nodes and resources, downtimes etc. These sites are organized by country and countries are organized by regions. The admins of each site can also update the information about the site.

Mr Alexey Poyda (Moscow State University), Mr Dmitry Mishin (Institute of Physics of the Earth Russian Acad. Sci.), Dr Mikhail Zhizhin (Geophysical Center Russian Acad. Sci.)01/03/2006, 18:30Demo sessionDemo contributionWe will demonstrate an environmental data mining project Environmental Scenario Search Engine (ESSE) including a secure web application portal for interactive searching for events over a grid of environmental data access and mining web services hosted by OGSA-DAI containers. The web services are grid proxies for the database clusters with terabytes of high-resolution meteorological and...

Mr Gergely Sipos (MTA SZTAKI)01/03/2006, 18:30Poster sessionPoster contribution1. Composing and executing data-intensive workflows on the EGEE infrastructure Grid computing is naturally very well suited for handling data-intensive applications involving the analysis of huge amounts of data. In many scientific areas the need for composing complex applications on grids from basic processing components has emerged. The classical task-based job description approach...

Nuno Filipe De Sousa Santos (Universidade de Coimbra)01/03/2006, 18:30Poster sessionPoster contribution1. Introduction Metadata Services play a vital role on Data Grids, primarily as a means of describing and discovering data stored on files but also as a simplified database service. They must, therefore, be accessible to the entire Grid, comprising several thousands of users spread across hundreds of Grid sites geographically distributed. This means they must scale with the number...

Domenico Vicinanza (Univ. of Salerno + INFN Catania)01/03/2006, 18:30Poster sessionPoster contributionData audification is the representation of data by sound signals; it can be considered as the acoustic counterpart of data graphic visualization, a mathematical mapping of information from data sets to sounds. Data audification is currently used in several fields, for different purposes: science and engineering, education and training, in most of the cases to provide a quick and effective...

Mr Jawher Kerrou (University of Neuchatel)01/03/2006, 18:30Poster sessionPoster contributionWorldwide, seawater intrusion and salinisation of coastal aquifers and soils is a major threat for food production. While the physico-chemical processes triggering the transport and accumulation of salts in these regions are relatively well known and well described by a set of partial differential equations, often it is extremely difficult to model accurately these phenomena because of the...
