  • We can merge files at most 50 runs (~7.5GB assuming fraction of good run is 100% safely).
  • Andreas' opinion : then rather make it file size dependent and merge to 1 or 2 GB. That's a size that one can still handle on laptops.

  • Optimal file size for merged file : 100MB ~ 10GB
  • Estimation of file size from cruzet runs
    • we have total 139 runs (cruzet2 + cruzet3).
    • 1 runs : ~ 190 MB (maximum)
    • 10 runs : ~1.7 GB (maximum among every 10 runs in sequence)
    • 100 runs : ~3.1 GB (first 100 runs)
  • Expected size per run in future : ~150MB per run

Things to modify in filesave_online.py
  • search tag like 'endrun_080701_141732' in /home/dqmprolocal/output/
  • transfer files correspoinding to that run
  • if file is the corrupted one, transfer xxx_T0000000xx.root
