Minutes:

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

Future Trends Conference

• Common theme to many such conferences where lengthy discussion regarding cooperation and standards is had, but small effect on industry
• Significant discussion on Research Software Engineer as a career path

Offsite Computing

• NERSC
  • AY2021 request submitted for GlueX
  • Agreed to return 10M of 50M unit AY2020 allocation to George Fai to distribute to other NP projects
  • Job bundling work anticipated to start next week
• IU - Big Red 3
  • Work starting this week to get GlueX jobs running on IU Big Red 3
• OSG
  • Some small issues recently, but are not due to JLab end
  • Making JLab SciComp available for OSG jobs
    • Need to set up Compute Element which is process that runs on head node at JLab and turns OSG requests into submissions to our SLURM system
    • Examples and documentation are identified, but implementation work needs to be done
    • Hopefully completed in Oct.

EVIO-6

• Numerous bugs identified and squashed in buffer reading code
  • Inherited code was initially written to read from files, but was modified to read from buffers
• Started looking into ReadTheDocs for package documentation
  • Proof-of-principle test performed to auto-generate documentation from GitHub source
  • Most existing documentation in MS Word format. ReadTheDocs uses Sphinx
  • Some tools exist to convert MS Word into Sphinx, but need to be investigated to see if the format conversion produces something appropriate.

JANA2

• 25/28 modules now ported. (Latest was ANALYSIS which was particularly complicated).
• Currently tackling event sources and plugins (event processors). The latter are more straight forward, but the former prevents linking and testing to begin.
  • Nearly have JEventSource_EVIOpp compiling without errors (primary EVIO event source class for GlueX)

AI

• Kishan running on sciml GPUs without out-of-memory issues seen a few weeks ago. Assume problem is fixed.
• Web page
  • Kishan has prepared some slides to show regarding a proposed content/format/management plan
  • Kishan, Thomas, and David will meet Tuesday to go over. (Chris T. is out of town this week).
• Hydra
  • Working now with Tensorflow 2.3
  • Some issues getting MirroredStrategy to work with flow_from_* methods (preloading images runs out of memory)
  • Common problem that does not seem to have a well-known solution at the moment.
  • May not be worth pursuing right now since training times have been reduced to a few hours
• DOE Report on AI town halls
  • Thomas read through and was inspired to think about a general use AI report class
• Accounts set up for the Experimental Controls projects. Job postings will be entered into the system this week.

SPACK

• Thomas has started reviewing documentation again in order to pick up where he left off before
• A group has already been set up on the CUE
• Permissions to some directories created by Wouter were made to be group writable

SRO

• Vardan out of town so no SRO report this week
