1. Training and the NGS Mike Mineter mjm@nesc.ac.uk mjm@nesc.ac.uk

2. Overview What is the motivation for new users?? What are trainers for? What is induction for?

3. E-Infrastructure vision Network infrastructure linking resource centres Operations, Support and training Collaboration Grid infrastructure

4. What are trainers for? NGS Goal: many effective and active users in many locations Technology is supported by a small number of people Training helps to make this feasible and scalable (EDG proved that!) Operations Early trainers users “Routine” training Web Helpdesk User doc. Consultancy VO

5. Without training…. Users uninformed, Support staff overloaded Operations users Helpdesk User doc. Consultancy VO

6. Without training…. Users uninformed, Support staff overloaded Downward slope Operations users Helpdesk User doc. Consultancy VO

7. What is induction for?? ALL Training courses need specific goals Leave participants on a clear path Induction is to orient potential new.. Users so they can understand the NGS, and make preliminary plans for  Grid-enabling their VO (data, code,…)  Further training needs (APIs, job/data services, portal development) Site managers/ sysadmin who might run resource centres  installation, admin courses also needed

8. What is in an induction course? Presentations Demo’s, case studies, walk-thru examples Do current users give GOSC demo’s and case studies? Why do they use NGS?! Practical Major topic for later! Built on EGEE course BUT EGEE convergence is some months hence

9. Proposed NGS Induction (plan A - October) What is grid computing Concepts, world-wide, EU and UK EGEE induction Security, AAA LCG-2 /EGEE-0 middleware Practical with GENIUS / GILDA Operations, (human) networking, middleware activities (WS and gLite) Overview of: NGS OGSA-DAI Oracle service SRB NGS Portal BUT convergence of NGS with EGEE is delayed pending gLite release & testing

12. Observations Event goals must match reality so an event is a point of departure for participants Useability, reliability, sustainability… are key goals of NGS and EGEE – but trainers need to set expectations accurately whilst the infrastructure is established.

13. Need for a training Grid For EGEE, GILDA testbed is hosted by Univ. of Catania (led by Roberto Barbera) Runs current production middleware Testbed for new applications (with support) Is a best-efforts service Lot of effort to ensure courses have response, pre- certified accounts Installation course needs are different Massive requirements for hardware 20 people, LCG installation course = ideally 100 PCs !

14. T-Infrastructure Training may require special e- Infrastructure T-Infrastructure emulates e-Infrastructure technical, operational and management aspects covered by courses T-Infrastructure may anticipate a future platform Authentication at (or just before) a course Authorisation may restrict imposed loads T ‑ Infrastructure may be operated in isolation Guarantees of availability and response
