Ferrara is involved in INFN-GRID (Grid.it) project.
The aim of INFN-GRID is the realization of a production grid.
The site configuration is almost the same as EDG.
INFN-GRID 1.0.0 (based on LCG 1.0.1, Red Hat 7.3) installed in:


1 Computing Element
1 Storage Element

SUN machines.
Upgrading to INFN-GRID 1.1.1 in the next 3 days.

Software Installation





The official release of INFN-GRID comes with Moose
rpm, including also the configuration files for the BaBar
VO.
Using BaBar release 12.4.0 + tags for ROOT output
(building a rpm for release 14.1.1a).
So, each italian site of the INFN-GRID project has
Moose installed by default.
The INFN-GRID Resource Broker is located at CNAF, at
the moment it sees only italian resources.
We would like to set up a Resource Broker for BaBar in
Ferrara, in order to registrate not only italian resources.
