Grid Interface Evolution
• 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
“robot”
certificate
– Good to expand the communities but difficultsto maintain
on “e-tokens”
• Web Interface
– GENIUS, P-GRADE
– Easier for new users but monolithic
• Science Gateways

Science Gateways
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

The GrIDP Identity Provider (1/2)
• 4 Identity Providers are available in GrIDP:
•
•
•
•
A “catch-all” IdP created at Catania;
The maat-G (enterprise) IdP;
INFN-AAI IdP (all INFN researchers and associates);
An idp that enables Social Networks credentials.

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 enable: Portlets as bricks
• Portlets can interact with the Grid
Infrastructure
e-
• 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
method.
