This makes the learning curve very steep and keeps non IT-experts away. 4

5. 5 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 Beijing, Asia 4, 11.04.2012 Riccardo Rotondo “robot” certificate s on “e-tokens” 5

6. 6 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 Beijing, Asia 4, 11.04.2012 Riccardo Rotondo 6
