The Monte Carlo Center

• Presently 5 ( 5) XEON bi-processors at 3.0 GHz
  _at_ CNAF (Bologna) allocated to MAGIC.
• During 2004 the MC production chain has been
  successfully tested,
• and worked fine ( 50 CPU used) 1 TB of disk
  space.
• see report from C.Bigongiari M.Piraccini,
  INFN Workshop Castiadas (Cagliari)
• Up to now produced ???K HE gammas events
• ??? hadron events

MAGIC 1

• Speed
• Timetot (Corsika Reflector Camera) 4s /
  event ? 900 events/h
• CPU
• If, for example, 11 Gevents of background are
  needed, this means 1200 cpu for 1 year
• the same background event can be used for
  different impact parameters
• ? 50 CPU
• Storage disk space
• Corsika output 28.0 KB/evt (g) 10.8 KB/evt (h)
• Reflector output 7.6 KB/evt (g) 1.3
  KB/evt (h)
• Keeping the reflector output 45 M g events ?
  320 GB
• 11G h events ? 13 TB

MAGIC 2

• We could provide 20-30 new dedicated machines _at_
  CNAF
• ? 40-60 CPU
• Also additional storage space
• One ( may be more) fellowships for a dedicated
  person will be available
• (particularly for the implementation into GRID)

Conclusioni

• CPU x produzione MC 50
• Storage x MC 13TB
• MC di MAGIC 1 interamente prodotto al CNAF
• CPU x Analisi Dati 10
• Storage x Dati 27TB
• (_at_ production centre)
