SICb Production at CLRC

CLRC's production processing for generating minimum bias events using different processor configurations. Data is exported to CERN with minor issues resolved, aiming for smooth operation and a projected output of 100,000 events per week.

  1. SICb Production at CLRC Chris Brew David Salmon

  2. Rutherford PC Farm • 1 Single processor Pentium PRO 200Mhz 64MB Memory 2GB HD • 4 Dual processor Pentium PRO 200Mhz 128MB Memory 10GB HD • 9 Dual processor Pentium II 450Mhz 128MB Memory 10GB HD • NT4SP4, LSF batch system

  3. SICb at RAL • Eric installed modified version of his web front end (21-22 Oct) • Data written to the RAL TapeStore and exported to CERN either on Physical tapes or over network • Various test runs since then threw up several minor problems - mostly to do with the writing the data to tape + precision problem as at CERN

  4. Generation of Min Bias Events • Production started 17th Nov. Should run smoothly from now • Generation of minimum bias triggers (360,000) • ~290 sec/event on slower processors • ~125 sec/event on faster processors • Projected output at 100% CPU : ~100,000 events/week
