PHENIX CC-J: Physics Requirement

• Simulation

  • 5 M events/year (0.5 % of exp. data)
  • data size: 6 MB/event, Storage: 30 TB/year
  • CPU requirement: 8200 Specint95, work disk Area: 3TB
    

• Data minig (?DST Production)

  • Taking into account of variety of physics goals of PHENIX we assume 10 independent ?DST productions / year
  • assuming DST is 150TB/year, 112MB/s tape I/O throughput is required
    

• Physics Analysis

  • Physics analysis will be performed for the ?DST many times.
  • We assume 1/5 of the ?DST (9TB) is resident in DISK
  • Assuming the access to the whole ?DST on DISK can be done 5 times in a day, disk read bandwidth is 520MB/s.
