EIC Software Working Group Expression of Interest

Markus' email from Friday 1/22/2021 (Click Expand to right ->)

Markus Diefenthaler Fri 1/22/2021 6:05 PM Hello, David, Dmitry, Douglas, Holly, Julia, Mauri, Nathan, and Sergey:

I hope you will be able to attend the Software Working Group meeting on January 27 (more details below).

Could you please help us with the work plan and send us your suggestions for how to realize the common projects in our Expression of Interest, in particular for how to get started? JLab will participate on many fronts.

Andrea, Torre, and I will collect everyone’s slides and sort them for the discussions with the whole Software Working Group.

Best regards,

Markus.

Begin forwarded message: From: Markus Diefenthaler <mdiefent@jlab.org> Subject: Expression of Interest, January 27, 9:00 a.m. (EST) Date: January 22, 2021 at 4:28:25 PM EST To: 'Maxim Potekhin' via EICUG Software Working Group <eicug-software@eicug.org>

Hello, everyone:

One of the next priorities of the Software Working Group is to develop our Expression of Interest into a work plan. We will discuss our next steps on Wednesday, January 27, at 9:00 a.m. (EST):

https://indico.bnl.gov/event/10382/ (connection information on Indico)

Please help us with the meeting preparation and send us a by the afternoon of January 26 a slide with the most important next steps you see. We will collect the slides and then use them to guide the discussion on January 27.

Best regards,

Andrea, Markus, and Torre.

Minutes:

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

• Announcements
  • Everyone encouraged to think about submitting paper to vCHEP2021

• SRO
  • Carl and Vardan worked to eliminate 2% dead time in Indra VTP test. Now is less than 0.1% w/ 1.3GB/s streamed from 2 VTP streams.
  • Aggregation of 2 streams matching hits by time slice
  • Ran over whole weekend and appeared stable.
  • Dave Abbott is modifying system to not use Trigger Supervisor
  • Vardan has compiled ATLAS SAMPA code, but system is currently offline so difficult to test.
  • David gave short update on INDRA-ASTRA meeting called by Markus D. last week. He will follow up with Holly on what she is looking for regarding SAMPA + TDIS
  • Streaming Data Scientist hiring committee made decision last week and HR has been notified. Unclear when they will notify the candidate.

• CODA
  • Feature request from Bryan M. to get livetime as measured by each individual ROC as opposed to only getting it from the Trigger Supervisor. Vardan is working with Dave A. on this.

• SPACK
  • Carl started looking into SPACK starting with a system on his Mac and writing a package for the Disrupter ring buffer package.
    • Some issues running SPACK that was not installed via homebrew
    • Nathan noted having numerous compiler and build issues on Mac OS X since November.
    • David suggested focussing on Linux for now since that is the platform everything has to work on.
    • Some discussion on using CLion (or other editors) locally, but with files stored on CUE. Nathan worked through a few options for Mac OS X. Some cause firewall issues, but he found a system that seems to work well.
    • Thomas and Kishan noted success using SFTP on Ubuntu.
  • David has been making slow but steady progress with SPACK getting all packages for JLab CE 2.4 compiled via SPACK on the CUE + CVMFS system.
    • He has created a github repository called epsci-spack where we can maintain packages and admin scripts.

• CLARA
  • Bug has been fixed regarding service name conflict.

• JANA2
  • (see discussion above in SPACK section on CLion and remote editing)

• Kishan is expecting to fly to Newport News on Feb. 18th.

• EIC + ACTS
  • Nathan has pushed some changes to ejpm. He believes Dmitry has merged them, though needs to check since there was quite a bit of other activity there as well.
  • Nathan reached out to ACTS authors to ask about all of the recent major version changes that implemented API changes that were not backward compatible. He wanted to know if it was worth upgrading the latest version, or if he should wait a bit for things to settle down more before putting in the effort. The reply was a bit vague.

• AI/ML
  • CPP (Charged Pion Polarizability)
    • Met with Andrew last week to discuss data sets needed to continue main part of work
    • Realized they need probably 3 months of work on the simulation.
    • Setting this project aside for the moment until a muon dataset becomes available.
  • Hydra
    • Kishan created a section on the benchmarking results in the paper targeted for CPC.
    • Abstract written for vCHEP paper but not much work done on it yet.
  • Thomas is working on proposal for Early Career Award
  • Several applications received for the positions that will be filled as part of the AI Experimental Controls Project
