      Announcement: b1pi test

Mark increased the number of events in the semi-weeklyb1pi test 
50 k to 150 k. The script was modified to run on the five platforms in 
parallel, facilitating this change. Also, Paul relaxed the probability 
cut on the kinematic fits a week or so ago, boosting the statistics in 
the related plots by a lot.

      Review of minutes from September 30

We looked over theminutes 

  * The schedule for work disk conversion to the new Lustre server has
    not been set yet.
  * Mark has started submitting jobs to finish off the last 20% of the
    Spring 2015 simulations.

      Data Challenge 3

Mark has started submitting jobs forData Challenge 3 
<https://halldweb.jlab.org/wiki/index.php/Data_Challenge_3>under a new 
SWIF-based system. This is the initial test of the system at this point.

      Future Commissioning Simulations

Sean gave a brief update on status. Aset of files for defining the jobs 
<https://halldweb.jlab.org/wiki/index.php/Sim1_Conditions>exists. We can 
start pilot jobs now. Mark agreed to take a look.

Brad asked about the recent fix to mcsmear so that it uses the correct 
run number to look up calibration constants. The current version of the 
code being for the Spring does not have this change. Sean browsed the 
code and the constants and did not find any cases where this would make 
a difference in results. On the other hand Brad reported significant 
improvements after going to the new code; he will look further to make 
sure that this particular effect is responsible for the changes he saw.

Sean pointed out that in any case, we should tag a new release before 
getting started with new simulated data sets.

      Auto-Build on Pull Request

Sean reported that the system is up and running now. He had some 
back-and-forth with Marty Wise of CNI on setting up the authentication 
system and those issues were worked out. Mark submitted a pull request 
earlier in the week that got auto-built successfully. The system writes 
a comment on the pull request at the the GitHub site. Those subscribed 
to sim-recon notifications will see the comment. It indicates success or 
failure and gives links to the error summary and build log file. The 
build is done on the ifarm and uses our work disk at present.

      The Meaning of the Run Number

Mark went over awiki page 
the discussion we had two meetings ago on the source and use of the run 
number in simulations. Richard had introduced the topic in the context 
of HDGeant4. Not only are there several possible sources for the run 
number (input events from generators, FFREAD cards) but there also could 
be a distinction between which run number is used to obtain calibration 
constants and which run number is output in the simulated events. 
Richard had made a proposal which seemed reasonable to the group.

      Binary distributions of GlueX Software?

Nathan is working on a system of packaging up the results of builds done 
with the HDPM system and creating a binary distribution of GlueX 
software. We is packaging sim-recon separately from the rest of the 
required software packages. There was agreement that such product would 
be useful, especially for collaborators outside the Lab starting out 
with the software. He will let us know how it is going at a future meeting.
