Minutes:

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

RealTime 2020

• Vardan gave highlights of some of the more interesting talks from last week.
  • Belle II switched to using zeroMQ for DAQ and increased throughput by order of magnitude
  • Talk on BDX experiment at JLab using TriDAS and waveboard
  • Deep Neural Networks are being used at CMS to distinguish τs from other jets
  • sPHENIX hybrid DAQ that combines triggered and streaming components. Expect to take data 2023
  • Project to generate HDL (Hardware Description Language) from Python. Early stages but intriguing

EVIO-6

• Carl has been reviewing options for documentation. He focussed some time on ReadTheDocs but found some issues
  • Language required is special markdown that has fairly steep learning curve
  • There does not appear to be a good way to pull in DOxygen generated documentation that produces usable results
• Explored some other options. ProProfs had a nice user interface, but does require expensive license.
• Settled on GitHub pages as probably the best solution. Use MS Word for user guide.
  • Nathan noted some issues with storing DOxygen in github repository along with code.

JANA2

• hd_root is now able to compile and run as far as reading in the "Go" and "Prestart" events which are the first two events in the first EVIO files from a run.
• Program does crash though so some more debugging needed

A.I.

• Webpages are now mostly updated with only things like Contacts page and some tweaks to Resources page left.
  • System is now working with Kishan submitting changes to Drupal site and David approving/publishing them.
• Hydra - Kishan is still working on revamping the scripts to more object-oriented style

CODA

• Vardan working with Bryan M. and Hall-A/C on archiving messages from daLog using cmb

SRO

• Vardan is working on porting some key components to C++
• Expecting permanent test setups (Indra lab, Hall-B) to be available soon. Will start testing Data Lake with Chris once that happens

Offsite Processing

• GlueX Production running at IU/BigRed3 now. Rate has been very good since Friday and nearly matching the rate currently obtained by GlueX from the SciComp farm at JLab
• NERSC multi-node job testing has been done and are now starting production there again.
  • Still issues to resolve with files brought back to JLab needing to be put on tape. (Unable to use swif2 mechanism that was used in the past.)
• PSC and JLab SciComp also in steady use so there are now 4 active clusters processing GlueX data (3 of them offsite).
