Message from Bob Michaels officially handing over ROOT responsibilities to EPSCI (Click "Expand" to the right for details -->): 

   BTW, I'm officially passing this job (building and maintaining ROOT) to you, now, David.
   If you need some help, let me know.  Of course, I can answer questions and help resolve
   problems with the old builds.

   yours
   Bob

   Dr. Robert Michaels
   Staff Scientist, Jefferson Lab

Minutes:

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

  • SPACK
    • Still some work needed for fully functional deployment
    • EPSCI has now taken over responsibility for building ROOT on CUE from Bob Michaels
      • Need some testing procedure to verify builds since it is more important than most software packages
    • CentOS8 has very limited support dates
      • We should drop spack support for CentOS8 and replace it with another OS based on what SciComp Ops is thinking
  • EIC
    • Met w/ Dmitry last week to discuss merging of efforts with ANL
      • Nathan looking at clarifying scope of project to convert ANL code from GAUDI to JANA2
      • Discussed need for additional personpower for supporting this effort. Request sent to upper management
    • ACTS
      • Nathan working on implementing ACTS examples with JANA2 to learn more about system.
  • JANA2
    • Nathan working on integrating with CLARA as a microservice
      • Some differences with basic data/execution flow between JANA and CLARA that need to be worked out
  • CLARA
    • Issue with occasional (<1%) of files being truncated when processing multiple files
    • With Raphaella's help, ran ~100 farm jobs and was able to decipher cause from log files.
    • Issue had to do with lost synchronization for one thread and a subsequent thread launched to process next file in list killed thread where original issue developed, masking it.
  • Data Transport -> EJFAT
    • EJFAT = ESnet/JLab + FPGA + Accelerated Transport (pronounced "Edge Fat" = fat data pipe from the edge)
    • Meeting today to discuss data format
  • SRO
    • Monday meeting had only a few participants and technical issues prevented lots of discussion
    • Some discussion of EVIO format of transient data (Dave A., Carl, T., Vardan G.)
    • Another test run by Vardan using software source:
      • 12GB RAM, 15 cores, 2.2GB/s
    • Some work with object pools
    • David challenged Carl to learn how to reproduce Vardan's performance tests independently
  • CODA
    • Carl continues work on EVIO-6 event viewer GUI
    • two minor user requests:
      • More verbose info from user scripts run during transitions
      • Support for setting more environmental variables in COOL
  • AI
    • FOAs + LDRD
      • Many discussions last week. We have potential involvement in several. Primary authorship on 1.
      • Thomas working on LDRD proposal to support work related to Early Career Award
    • Jupyterhub
      • Kishan tested running training on GPU via Jupterhub and the epsci-notebook. Some library errors.
        • Communication with Wes led to adding secret libs directory (.singularity.d/libs) to LD_LIBRARY_PATH coupled with CUDA installation in /apps formed working system.
    • Experimental Controls
      • Torri met with Noami yesterday who pointer her to some software and gave tour of DB.
      • Able to run plugins over raw data and generate ROOT files. Next step is to examine contents.
  • Offsite Computing
    • GlueX is working on revised XSEDE proposal (Due April, 15th)
    • OSG
      • Job queue has been steadily catching up since removing lustre mounts from scosg16
      • Some issues have arisen in the last day that looked to have caused a slow down. They are being investigated.
      • Changes made to monitoring that make it appear as though it is updating faster
