ZOOM. To participate you must register in advance on: Registration for Dirac2020 zoom

After your registration has been approved, you will receive a confirmation email containing information about how to join the meeting.

The DIRAC meeting is a family reunion for DIRAC developers and DIRAC friends. Dirac users are very welcome to participate, it is a nice opportunity to meet the people behind the DIRAC code. There is no registration fee but you need to register on the link above to get access to the online meeting over zoom.

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.)
