ZOOM (registration required; see DIRAC developers list).

The DIRAC meeting is a family reunion for DIRAC developers and DIRAC friends. We will discuss science, but a significant part of the program is reserved to discuss the future of the DIRAC code, programming, code maintenance, release planning, as well as for programming task groups.

The meeting program is self-organised, simply add talks and discussion points to the program. (Send an e-mail to Hans Jørgen using hjj at sdu.dk if you do not have editing permission to this page.)

• Go through issue list on dirac-gitlab
• Prepare release of DIRAC21
• Discuss when and how to release DIRAC22
• Document: how to unprotect branches, how to add a track to dashboard, who has access
• Work on history clean-up before we can open source the master/main branch
• Update CMake code

• proposal for summit
• discussion on finite field implementation RELCC / ExaCorr
• ExaCorr / ExaTensor performance ?
• update on X-AMFI (replacement for AMFI)

Please sign up for your presentation (one or possibly two, if different topics) in one of the free 30 min time slots below, you can also add it here if you will let the organizers determine your time slot. Plan you presentation to 20 min, leaving 7 min for discussion and 3 min for changing speaker.

“Technical talks” refer to talks about development tools, “how to” etc.
