  1. Regular items
  • The open requirements, pending actions, status of long open bug reports, as well as physics and computing performance monitoring are reviewed.
  • Issues on both physics and computing performance arose during the release phase of version 10.3 were discussed. See the next agenda item.
  1. Version 10.3 Release
  • For information: SVN has now reached more than 100000 commits !

  • Release 10.3 has been delayed for one week.

  • The delay of 10.3 was due to hadronics code which was introduced to testing very late, after the fixed deadline and during the bug-fix release phase, together with 3 new data sets. This originated problems requiring additional time and effort to identify and fix.
  • Some other large code (DNA) committed at the very last minute in one block rather than granular committals has caused disruption in testing.

  • The Steering Board agreed to enforce the rule that the last reference tag in a release should include all developments (including all physics developments), as it is foreseen from the release procedure. Following candidate tags should only address technical migrations and fixes.
  1. 2017 Collaboration process
  • Membership is to be renewed in January through the CA web page.

  • Each WG should make census to be finalized by the end of January. Each member will hence be contacted by the WG coordinators to provide his/her FTE in each WG he/she is involved in.

  1. New collaboration logo
  • Second-round vote among 4 finalist candidates ended up with three out of four which got exactly the same number of ballots (fourth classified was only one vote less).

  • The Steering Board will reiterate the process for the final decision and will announce to the Collaboration.
