Questions of the Referees:
Using the charm spectroscopy setup, COMPASS will write about 50
DLT-7000 tapes (30 GB each) per day, over a period of 100 days or
more. Could you describe:
- How the calibration of the various detector components will be done
(for each tape? for every n'th tape?)? Is "online calibration" (like NA48)
- Do you foresee central data recording, or local mounting of tapes?
- Will the processing farm be at CERN?
- If so, will the data be stored at the farm or centrally?
- How the tapes will be processed (how many processors, tape
- If the processing is done at CERN: what will be the load on the
CERN network? Will there be any central facilities used? If yes, which
- With respect to the WA89 or WA102 reconstruction speed, a factor
of about 1000 has to be gained. How will that be achieved?
In the following we discuss possible scenarios for the offline data
handling at the COMPASS experiment. Data rates and event complexity
in the hadron program of COMPASS will be slightly higher than in the muon
program. The benchmarks for the capacity of the COMPASS offline data
processing will therefore be set by the hadron program. All estimates
below are given on this basis.
