GSI

Users have to cope with complex security procedures,

execution scripts, job description languages, command

line based interfaces and lack of standards.

This makes the learning curve very steep and keeps

non IT-experts away.

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– Good to expand the communities but difficult to maintain

• 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

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 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 method.
