[Craig Bookwalter]

Hi folks,
  Minutes from today's meeting can be found at:

http://clasweb.jlab.org/rungroups/g12/wiki/index.php/04Nov09

and pasted below.



Agenda

    * Review last week's meeting minutes
    * Pass1 status (FSU/JLab)
    * Tagger energy study (motivated by Craig's beam energy spectrum shown
here)
          o Plots from before (56410) and after (56490) the `major'
trigger change. Plots are from a skim of pi+pi+pi- events. The
notch seems to be at the same place where the paddle sizes
change (t_id == 19).
    * Other items


Minutes

    * Attending: Valery, Dennis, Johann, Mike, Diane, Craig, Paul, Mukesh,
Ben
    * We are approaching the 50% mark in pass1 cooking at JLab.
    * Discussion on the tagger energy distribution was inconclusive --
Dennis would like to see a beam energy plot normalized for counter
size; it would also be nice to get Eugene Pasyuk involved to hear what
he thinks about what's going on. We would also like to look at the
output from g12_monitor to confirm this is a global problem. Valery
thinks it make be a bug in the software.
    * Mike is working on benchmarking 32 vs 64 bit builds on a 64 bit
platform -- currently a1c is giving only the HEAD, EPIC, and TESC
banks.
