The gLite information system: Top BDII Giuseppe Platania INFN Catania Tutorial per gli Insegnanti degli Istituti Tecnici Industriali Acireale, 4-7-11-13.05.2007

Outline Top BDII overview Differents between Top BDII and Site BDII The GLUE Schema Overview Core entities Embrace Tutorial, Clermont-Ferrand, 9-13.10.2006

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. Embrace Tutorial, Clermont-Ferrand, 9-13.10.2006

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,CE2 ..... 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 Embrace Tutorial, Clermont-Ferrand, 9-13.10.2006

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) Embrace Tutorial, Clermont-Ferrand, 9-13.10.2006
