What are trainers for?
NGS Goal: many effective and active users in many locationsTechnology is supported by a small number of peopleTraining helps to make this feasible and scalable (EDG proved that!)

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
What is in an induction course?
PresentationsDemo’s, case studies, walk-thru examples
Do current users give GOSC demo’s and case studies? Why do they use NGS?!
PracticalMajor topic for later!
Built on EGEE courseBUT EGEE convergence is some months hence
Proposed NGS Induction (plan A - October)
What is grid computing Concepts, world-wide, EU and UK
EGEE inductionSecurity, AAALCG-2 /EGEE-0 middleware Practical with GENIUS / GILDAOperations, (human) networking, middleware activities (WS and gLite)

BUT convergence of NGS with EGEE is delayed pending gLite release & testing

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.
Need for a training Grid
For EGEE, GILDA testbed is hosted by Univ. of Catania (led by Roberto Barbera)
Runs current production middlewareTestbed for new applications (with support)Is a best-efforts serviceLot of effort to ensure courses have response, pre-certified accounts
Installation course needs are differentMassive requirements for hardware 20 people, LCG installation course = ideally 100 PCs !
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 platformAuthentication at (or just before) a courseAuthorisation may restrict imposed loads T‑Infrastructure may be operated in isolationGuarantees of availability and response
