David sent around an email 
asking about interest in having the lab be a satellite site for an HPC 
Summer Boot Camp that teaches fundamentals in parallel programming to be 
held June 3-6. If you have an opinion, please contact David by April 17.

      Review of minutes from the March 5 meeting

We went over the minutes 

  * David reported that Batch 3 of the reconstruction of Spring 2018
    data is complete. Batch 4 was submitted to NERSC earlier today.
  * David, Alex, Curtis Meyer, and Amber Boehnlein submitted a proposal
    to the Pittsburgh Super Computer Center for enough time to do a
    single reconstruction pass on the Fall 2018 data (7.65 SU's).
    Requests take about two weeks to be evaluated.

      Report from the last HDGeant4 Meeting

We went over the minutes from the meeting on April 9 
We though that Peter might want to pick a few items from his comparisons 
between G3 and G4 and post them as issues on the HDGeant4 page on GitHub.

Naomi brought up a couple of separate issues with HDGeant4:

 1. The number of events to be generated can be specified in the macro
    that starts the job or in the control.in file. We don't which is
    controlling. David mentioned that he has requested that it be
    specify-able in control.in to maintain symmetry between hdgeant and
    HDGeant4. We again suggested that this was an appropriate issue for
    the HDGeant4 GitHub site.
 2. The "-r" switch for setting the run number does not work.

      IT Reorganization

Mark described recent personnel changes 
in IT Division.

      PrimEx branches in HDDS

There is a new system for maintaining alternate geometries in the Git 
repository. Richard and Sasha described it in a recent email exchange 
Recall that the geometry for reconstruction should be coming from the 
CCDB and not the Git repository. The versions in the repository are only 
for developing new geometry configurations. In the repository it is 
important that distinct geometries be kept on separate branches. 
"Merging to the master branch" is a disaster in this case.

      Review of recent issues and pull requests

We reviewed issues for halld_recon and halld_sim. We discussed how to 
prioritize work on the various issues. In real time, Sean assigned 
color-coded labels <https://github.com/JeffersonLab/halld_recon/issues> 
to all of the extant halld_recon issues. Issue #71, Crash in ST matching 
<https://github.com/JeffersonLab/halld_recon/issues/71> is marked as the 
highest priority issue, as we agreed.

      General Documentation in Need of Update

Hovanes remarked that the general documentation for the GlueX software 
on the wiki page is inconsistent and out of date. No one disputed his 

      CCDB Development

Sean and Mark will meet with Dmitry to plan work to address the issues 
reported with CCDB.
