EGEE Tutorial

How to get started

Scope

• We are using the GILDA testbed today– The production EGEE grid looks like this!– Current EGEE production middleware

• The practical exercises are to illustrate “how”– Not using typical jobs for running on a grid!!– But to show how grid services are used, jobs are submitted,

output retrieved,…

• We will use the Command-Line Interfaces on a “User Interface” (UI) machine– “UI” is your interface to the GILDA Grid

Where your digital credentials are held Client tools are already installed

GILDA is “t-Infrastructure”

• Why t-infrastructure? – Training is necessary!– e-Infrastructure for production – t-Infrastructure for training

• Need guaranteed response for tutorials; limit the vulnerability of production systems – use training grid – have training CA – able to change middleware to prepare participants for

future releases on production system – need safe resources for installation training – easy entry point for new communities
