    Minutes, HDGeant4 Meeting, June 4, 2019

Present:

  * *JLab: * Shankar Adhikari, Thomas Britton, Mark Ito (chair), Simon
    Taylor, Beni Zihlmann
  * *UConn: * Richard Jones

There is a recording of this meeting <https://bluejeans.com/s/t5u36/> on

We had a desultory discussion, largely off agenda. Some random notes:

  * The SKIP command is now working in both hdgeant and hdgeant4.
  * Richard has been working on implementing an intermediate buffer for
    EVIO reads in DANA
    <https://github.com/JeffersonLab/halld_recon/pull/165>. When using
    XROOTD to read EVIO-formatted raw data files the I/O speed
    improvement is about factor of 40.
  * Thomas has been working with Wes Moore of IT on standing up an
    XROOTD server on the submit host (scosg16.jlab.org). They have
    succeeded in streaming random triggers from the submit host to OSG
    sites. A Really Big Step (RBS).
  * We had a rather long discussion about submitting to non-OSG compute
    resources with OSG methods using the submit host. All agreed that
    this is desirable. Richard has shown proof-of-principle with his
    work with Bosco.
