Announcements

  • Bluejeans now has virtual backgrounds

GUI For Calorimeter Calibration System in Hall-D

  • Thomas working on at request from Igal
  • Front end done
  • Gave 1 year time scale
  • Some evidence Igal's workflow is heavily burdening hallddb.jlab.org

NERSC

  • Processing of GlueX Spring 2020 dataset has started
  • Job throughput is very modest
  • May need to consider bundling jobs
  • Perlmutter will change situation dramatically in 1 year. (how much to invest?)

OSG

  • Multiple distribution technologies
    • cvmfs oasis - useful for code distributions - using both JLab VO and GlueX VO
    • stash cache - useful for larger files (e.g. random triggers) that could be used at multiple sites - federated storage that relies on xrootd
    • xrootd - used for transporting data (e.g. raw data)
  • Running OSG jobs onJLab SciComp farm
    • head node is being stood up now
    • still 1 month or so away from functioning
  • Collector at JLab still not fully functional due to network issues
    • UCSD still in use as primary for the moment

SPACK

  • Space on JLab CUE is being set up
  • Web server is process of being set up. (Sherman now in charge of web servers)
  • JLab CE replacement still about 1 month out. Oct. may be more realistic

EVIO-6

  • Full C++ port of Java code is complete
  • Testing phase has started

A.I.

SRO

  • ERSAP Prototype
    • Multi-threaded I/O services working
    • Demo 10GB/s from 12 simulated streams through data lake (all on same node so no network hardware involved yet)
    • Redis data lake issue resolved by reconfiguring to use multiple threads
    • Vardan will report at EIC meeting immediately following this one

JANA2

  • GlueX Port
    • Merged numerous changes required of JANA2 into master
    • Working on test cases
  • Documentation
    • Investigated using ReadTheDocs. Breathe is tool that can help convert existing DOxygen documentation to ReadTheDocs (Sphinx) format.
  • A.I. support
    • Considering OpenCV over Tensorflow for C++ interface
    • Issues calling python interpreter from JFactory
      • Python interface is one option for inferring on GPU from JANA
      • GIL may be related to the issue
