1. SuperB – INFN-Bari
Giacinto DONVITO

2. Site configuration ~ 1000 Core shared among several VO/groups
10% of this resources could be used by “not founding” VOs
Farm accessible both from local batch system and grid
Two different CEs: lcg-CE and CREAM-CE
~500TB of storage
Available locally with Lustre (distributed) file-system
We provide SRM end-point by means of a StoRM installation

3. Experience on supporting SuperB
The farm is reconfigured to support also SuperB activities:
The required list of (32bit) libraries where installed on all the WN
Exploiting a local tool that enforces the consistency between WNs
The Lustre file-system is configured such a way that the SuperB users could access both using SRM interface and locally to the SuperB area
Reading from lustre as a local file-system is already possible
Specific ACLs are configured in order to allow also writing on lustre without using SRM interface
This will increase the performance and the reliability in writing the output

4. Problems encountered
Writing to lustre file-system requires particular set-up of “umask” at user level
Long jobs failing due to a configuration error at site level =>
Fixed!

5. SuperB activity: future
In the future, Bari will join the distributed computing infrastructure in order to provide Tier1 computational resources to SuperB experiment
Both network (1Gbit/s now, 10Gbit/s in the near future) and the infrastructure will easily fit with the requirement of the experiment
