Grid Interface Evolution
Enabling Grids for E-sciencE
• The way users access Grid resources has
continuously evolved towards simplicity and
transparency:
• Command Line
– Globus and gLite CLI
– Used by the enthusiastic and early adopter scientists
• GUI applications
– gEclipse, Grid2Win
– Good to expand the communities but difficult to maintain
• Web Interface
– GENIUS, P-GRADE
– Easier for new users but monolithic
• Science Gateways

Science Gateway
Enabling Grids for E-sciencE
A framework of tools that allows scientists to run
applications with little concern for where the
computation actually takes place. This is similar to
cloud computing in which applications run as Web
services on remote resources in a manner that is not
visible to the end user. However, a science gateway
is usually more than a collection of applications.
Gateways often let users store, manage, catalogue,
and share large data collections or rapidly evolving
novel applications they cannot find anywhere else.
Training and education are also a significant part of
some Science Gateways

Liferay
(www.liferay.com)
• Highly-configurable, scalable, open source
portal framework;
• Compatible with JSR 168/286 standards
and based on modern web 2.0
technologies;
• Liferay services planned to be used:
– Portal;
– CMS & WCM;
– Collaboration and “social” software

Grid Access – Portlets as bricks
Enabling Grids for E-sciencE
• Portlets can interact with the Grid
e-Infrastructure
• Different approaches are available:
– Execute the Command Line behind the portal;
– Using API where available:
 Must be in Java or other languages supported by Liferay;
– Call REST services from Javascript code in the browser;
• Additional layers between Liferay and the Grid
can be necessary for some services;
• Each portlet can follow its own communication

The DECIDE Project Objectives
Enabling Grids for E-sciencE
(www.eu-decide.eu)
• Provide the Neuroscientific and Medical
community with a dedicated production
quality e-Infrastructure;
• Deploy a secure and user-friendly service
for the early diagnosis and research on
Alzheimer Disease and forms of
dementia.

The INDICATE Project
Enabling Grids for E-sciencE
(www.indicate-project.eu)
• Enable the Digital Cultural Heritage
Community to access to two different
e-Infrastructure repositories:
– the archive of Architectural and Archaeological Heritage
present in Mediterranean Area;
– the Federico De Roberto literary works.

Conclusions and outlook
Enabling Grids for E-sciencE
• Conclusions
– Using different frameworks it is possible to build a Science Gateway
able to interact with Grid Services;
– Liferay is the most used framework and offers an easy,
customizable and user friendly interface;
– Thanks to robot certificates and X.509 standard the level of security
is kept high and the resources safe;
– The new “bricks” developed are being used in two projects
belonging from two distinct scientific domains.
• Future Work:
– While the role of Liferay as “front-end” is clear, the interactions of
the tools behind are still under development;
– Test the new Science Gateway in a production environment:
 The goal of DECIDE is to provide a production service.
