Minutes:

Attendees: David L., Carl T., Nathan B., Thomas B., Vardan G., Kishan R.

SRO

• Design of Data Lake component
  • Hall-B setup "2" absorbed into TriDAS setup so only a single system exists now
  • Looking to evaluate 3 other Data Lake options
  • Chris L. is looking at designing a Data Lake from ground up.
  • Indra hardware not fully set up yet
• Some work started between Vardan and Carl on stream aggregation (event building)

JANA

• Close to having something for Kishan to test with heterogeneous hardware
• Some optimization was done with time delays to increase event rates for jobs requiring little processing
• Modest advances on GlueX port

A.I.

• Town Hall
  • 24 Talks. Most were a little heavier on physics/experiment details than A.I. (as expected)
  • Need to post slides (David will request)
• JANA2
  • Found path to save models built in Keras and read them back in with C++
  • Model identified for testing
  • Will use Inception V3 or similar with random weights for testing on GPU

Offsite Computing

• GlueX Data Processing
  • NERSC is providing very minimal amount of processing
  • PSC is similar to last year and fairly steady at ~300 files per day
  • Will hand off day-to-day to Igal J. in Hall-D later in the week
• OSG
  • First jobs coming to JLab "relatively soon"
  • Only JLab related jobs will be allowed at first

EVIO-6

• Coming to end of debug run
• Next, will start working on updating documentation

SPACK

• Wouter will give talk on SPACK Wed. @ 3pm on bluejeans (id: 702 801 637)
