The name of the game

• Three farms in Italy today
• MC for official Simulation Production
  (formerly at Caspur, now at INFN Rome)
• Analysis a Tier B with Kanga data located at
  Caspur (Rome)
• Repro located in Padova, will reprocess all
  Babar Run1Run2 data starting this summer

MonteCarlo Farm Upgrades

• 2002 increase production to 6-8 Mevents/month
• clone Linux farm
• 17 2-CPUs, 1.26GHz, 1 GB RAM installing now
• Server and disk (1TB) ordered
• use Analysis farm resources when available
• Problems with a Sun disk (1TB), recovering
• 2003 increase production to 20 M events/month
• more CPUs (15030SpecInt95 35 1.6GHz 2xCPUs)
• use repro farm whenever possible

12
Analysis Farm Today

• 5 Sun E450, 4x400 MHz, 2GB (NFS data server)
• 15 Linux clients, dual cpu, PIII 1 GHz, 1 GB
• 1 Sun Ultra 10 lock server
• - 1 Sun Ultra 10 monitoring (to be dismissed
  soon)
• Disk space 9 TB for Kanga
• Data AllEvents 8 streams. The complete (99-02)
  dataset is available
• MC 650M events available
• Private Toy MC
• SP MC production as infn2 (lower priority wrt
  analysis)

• Disk from Padova (?)
• maintain Kanga until end of reprocessing, (spring
  03)
• Next Computing Model Working Group
• OBJY vs. non-OBJY Event Store, MINI vs. MICRO,
  etc

Babar-Grid

• Some activity going on in Italy
• Define and implement a Grid-scheme for MC
  production
• Installing/testing on the INFN-Grid Ferrara
  testbed
