The GILDA t-Infrastructure(https//gilda.ct.infn.
it)
GILDA is an international effort funded by
different sources.
4
and the Projects using GILDA
GILDA is really serving EU FP6 grid projects.
5
The GILDA Testbed(https//gilda.ct.infn.it/testbe
d.html)
20 sites in 3 continents (3 sites belonging to
ICEAGE!)
6
How to join GILDA
Clear instructions for different kinds of
learners (users, sysadmins) about how to access
the t-Infrastructure.
7
The GILDA Certification Authority(https//gilda.c
t.infn.it/CA)
Makes the complex grid authentication procedures
easier both for direct and self-paced
learners.
8
The GILDA Virtual Organization(https//voms.ct.in
fn.it8443/voms/gilda/)
600 people registered in the GILDA VO! 400
real users 200 generic users 30
educators

10
The GILDA Portals
Easy to use. Hide the complexities of the
middleware if this is not the topic to be
taught. Extremely useful also for self-pace
learning.
11
Grid in a box the GILDA User Interface
PlugPlay (https//gilda.ct.infn.it/UIPnP/)
Can be used in all kind of courses. Ideal for
self-paced and/or remote learning.
12
Grid in a box/room the GILDA Virtual Services
(t-Infrastructure scalability)(https//gilda.ct.
infn.it/VirtualServices.html)
Wiki pages available
3 TB of virtual software services already
downloaded!
13
The GILDA Training Material(https//grid.ct.infn.
it/twiki/bin/view/GILDA/WebHome)
70 topics (user induction, grid services
installation and management, application
development) with plenty of exercises. Three
levels of difficulty Basic, Medium, and
Advanced.
14
(Some) University courses using GILDA(several
countries, several languages)

• The ICEAGE t-Infrastructure scales beyond its own
  limits and enables an effective tech- nology
  transfer.
• GILDA is not only bookable on-demand
• but it is also clonable on-demand.
• Thanks to ICEAGE, big opportunities
• for a new training open up for educators.

Middlewares co-existence in GILDA (1/2)

• GILDA is not any more gLite centric. In the
  context of ICEAGE (triggered by the requirements
  of Summer Schools), the GILDA Team has carried
  out an important study about the co-existence of
  several middlewares on the same physical
  computing and storage resources.
• Present results
• Super User Interface a machine (real or virtual)
  with a gLite User Interface, a Globus Toolkit 4
  (GT4) client, and an OMII-UK client on board.
• Super Computing Element the same Torque/MAUI
  farm can execute jobs coming from gLite, GT4, and
  OMII-UK.
• The same GILDA CA certificates can be used with
  all the 3 different middlewares.
