Note: Mark started the meeting in the wrong BlueJeans meeting room so 
remote participants did not get the full experience of the meeting. Like 
none. Apologies from the chair.


      Announcements

 1. New version set: version_4.8.0.xml
    <https://mailman.jlab.org/pipermail/halld-offline/2019-August/003746.html>
    Several packages received update releases in this version set. There
    was a glitch rolling out the new default version last Friday
    (version set-up would not work), but it got fixed before noon.
 2. Due to schedule conflicts, the HDGeant4 meeting time has changed. It
    will be at 2 pm rather than 3 pm. It will be held every other
    Tuesday as before.


      Review of the Minutes from the Last Meeting

We went over the minutes from August 20 
<https://halldweb.jlab.org/wiki/index.php/GlueX_Software_Meeting,_August_20,_2019#Minutes>. 


  * Beni wondered if the TPOL people were concerned about having a
    *partial sample of the PS triggers* collected during online skims.
    David reported that he had not received any communication on this.
  * *NERSC processing*. David reported the batch 1 of the Fall 2018 data
    processing is essentially done and jobs for batch 3 were started at
    NERSC over the weekend in the low priority pool. We have received an
    additional 4 mega-units from unused allocations of other users at
    the NERSC. Batch 2 is in progress on the JLab farm. In addition
    batch 4 has started the Pittsburgh Supercomputing Center using an
    "advance" allocation while our proposal is being evaluated. The
    advance is 10% of the full allocation and should get us through
    about half of batch 4. This means we are now running at three
    facilities at once.


      Time History Plots of Offline Computing Resource Usage

Mark described a system he has developed to capture time histories of 
any quantity of interest. He has deployed it to track data on offline 
computing resource usage by Hall D at JLab. See his slides 
<https://docs.google.com/presentation/d/14NKsoqlyQWAvKenk64DvqqyMiUHoRvginkf-0qneG_4/edit?usp=sharing> 
for details. The new webpage can be found here 
<https://halldweb.jlab.org/disk_management/halld_status.html>. See the 
recording for a tour through some anomalies recently discovered using 
the tool.


      Review of recent discussion on the GlueX Software Help List

The issue Justin Stevens raised 
<https://groups.google.com/forum/#!topic/gluex-software/GI2vb7VFtmU> 
about hdgeant4 missing needed shared libraries on the farm nodes at JLab 
has been resolved.
