5. Ferrara - 12/02/035 CE / WN SE u The DataGrid Testbed consists of different types of machines (Grid Elements). u In Ferrara the farm is composed by one Computing Element (CE), three Worker Nodes (WN), one User Interface (UI) and one Storage Element (SE). u All these machines are managed by a LCFGng (Local ConFiGuration system new generation) server and they are automatically configured. UI LCFGngServer Grid Elements in Ferrara

6. Ferrara - 12/02/036  UI (User Interface): component for accessing to the workload management system.  Users can submit a job and retrieve the output, they sholud have an account and a personal certificate installed in their home directory. UI Certificate Authorities To access the GRID you have to request a certificate to a certification authority. INFN-GRID users can obtain a certificate from the INFN CA (http://security.fi.infn.it/). User Interface To use the BaBar Grid, you must register that certificate with the BaBar Virtual Organisation (BaBar VO). http://www.slac.stanford.edu/BFROOT/www/Computing/Offline/BaBarGrid/registration.html

9. Ferrara - 12/02/039 Configuration  INFN Grid Testbed Status: EDG 1.4.3 (RedHat 6.2).  A BaBar software special release (12.3.2y) has been built and installed to: Write Kanga files Run Moose on RH 6.2  A special tag of ProdTools has been installed to perform tests.  A pool of BaBar accounts (babar000, babar001,…) has been created in the EDG farm of Ferrara.  Each member of BaBar VO is able to submit jobs to the farm of Ferrara through the RB located at CNAF (grid009g.cnaf.infn.it).

10. Ferrara - 12/02/0310 Current Status  Created a JDL file to run Moose on Grid resources.  Created scripts containing EDG commands to submit jobs, to check their status and retrieve output files.  An user can submit a range of runs.  For each run a job is created and submitted to the Resource Broker, then it is sent to the Ferrara CE (grid0.fe.infn.it).  The output file is then transferred to the closest SE (grid2.fe.infn.it).
