5/2/2005 MAGIC II Workshop – RömerTurm 1

The Monte Carlo Center

Presently 5 ( + 5) XEON bi-processors at 3.0 GHz @ 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 1Speed:

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 () 10.8 KB/evt (h)• Reflector output: 7.6 KB/evt () 1.3 KB/evt (h)

Keeping the reflector output: 45 M events 320 GB 11G h events 13 TB

MAGIC 2• We could provide ~ 20-30 new dedicated machines @ 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)
