Minutes:

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

• DAQ
  • SRO
    • INDRA Lab test bed pulser data rate doubled to 600MB/s per stream
    • Able to process 1.3GB/s of data w/ 100% livetime
    • Chris L. now has access to properly formatted payload data that can be used for software source
  • CODA
    • Reset, Pause, Resume user script feature added
  • EVIO-6
    • C implementation done. Development was done on Mac so compilation/testing needs to be done on Linux.
    • uses high-performance ring-buffers from disruppter-cpp package (C++ port of LMAX disruptor)

• Frameworks
  • CLARA - nothing to report
  • JANA2 - janadot now working

• A.I.
  • Hydra benchmarking is done. Currently able to process images on single GPU system at ~3Hz
  • some potential areas of optimization, but current rate is sufficient for any current needs
  • A.I. institute proposal still needs work

• Offsite Computing
  • Bridges-2 Early User Program allocation granted for GlueX

• JLab Common Environment (CE) + SPACK
  • David showed slides on current work on the epsci SPACK implementation
  • Singularity containers for 3 OSes now exist
  • CVMFS directory is now set up and functional, though packages are not all built and configured
  • Website gives access to buildcache, though it is unclear how viable of an option this will be.
  • Need to coordinate with EIC group (Wouter and Dmitry)
