Overview
Core entities
Embrace Tutorial, Clermont-Ferrand,

3. BDII overview It's entirely based on LDAP
Every node (except UI,BDII and Wns) has a GRIS service in order to publish its informations
A node in every site collects all site GRISes and publishes them using a site BDII, usually installed on the CE
The top BDII collects all site BDIIs
From the UI a user can run a set of commands to query the top BDII.

4. Top BDII vs Site BDII Site BDII Top BDII
By default it is installed on the CE
It collects all site GRISes* (for example SE,RB,LFC,etc..)
The name of the service is bdii
Top BDII
It collects all site BDIIs** (CE1,CE CEn)
It's contacted by the RB to match and dispatch user's jobs
It can run in the same machine where the RB is running (it's more fast in answer)
*GRIS=Grid Resource Information Service
**BDII=Berkely Database Infomatin Index

6. GLUE: Grid Laboratory Uniform Environment
GLUE: overview
GLUE: Grid Laboratory Uniform Environment
It’s an information model that describe all those resources that partecipate in the Grid system and that are requested to be discoverable and monitored
The same information can be retrieved from different GISs relying on different technology (e.g. R-GMA)
