Computing Capacity

• Run I : ~900 MIPS
  • Rate: 150 events/sec
  • Decision Time: 3 MIP-sec/event ( 0.15 seconds on 20 MIP VAX‘s.)
    • Tracking
    • Calorimetry
    • Muon
  • Average Utilization Factor: 50%
• Run II requirements: 12k MIPS
  • Rate: 1000 events/sec
  • Decision Time:
    • unchanged
    • Cal, Muon code similar: 2 MIP-sec/event
    • CFT r-f tracking: 2 MIP-sec/event (0.02 sec/event on 100 MIP CPU).
    • New code (Silicon, E/p, PS) : 4 MIP-sec/event?
  • Average Utilization Factor: 67% (conservative)
• Capacity: >30k MIPS
  • 48-64 quad nodes
