The 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 ...

Introduction
The Baltic Grid project, a FP6 program, involving 10 leading institutions in six
countries, started in November 2005. Its aims to i) develop and integrate the
research and education computing and communication infrastructure in the Baltic
States into the emerging European Grid infrastructure, ii) bring the knowledge in
Grid technologies and use of Grids in the Baltic...

Created 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...

The 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...

The 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...

The 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...

In 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...

This 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.

organizations were established in the Russian Data Intensive Grid (RDIG)
consortium.

We present an IST project of the 6th Framework Programme, aimed to create a
distributed framework for multi-risk assessment of natural disasters that will
integrate various models for simulation of forest fire behavior and effects, flood
modeling and forecasting, landslides and soil erosion simulations. Also, a
distributed repository with earth observation data, combined with field...

1. 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...

1. 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...

Data 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...

Worldwide, 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...

In the Grid dissemination activity, teaching of Grid elements installation covers a
very important role. While in tutorials for users availability of accounts and
certificates is enough, in those ones for administrators a certain number of free
machines is needed, and the requirements for a Grid-middleware compliant operating
system also occurs.
