Notes version: 0.3: J Apostolakis, 2nd February 2005
1. Initial Items
Minutes of TSB meeting of October 8th, 2004 approved.
Actions closed: 27.1, 27.14, 28.1, 30.1, 30.5, 30.6, 30.9, 30.11.
Progress/almost done: 27.4, 30.7, 30.12 .
2. Releases
Release 7.0 issues
Migration to <cmath>
Action (G Cosmo): inform category coordinators about methods for migrating to use of <cmath>.
Action (category coordinators) verify consistency of results after move to <cmath>, in particular for the logarithm.
Move to CLHEP 1.9 and evaluation of 2.0
System testing is using CLHEP 1.9.1.1, as ‘new’ in dev area. Agreed to make it ‘pro’. Anticipating version 1.9.1.2, and expect minimal impact in change.
Agreed to do release validation testing using final CLHEP for release.
Report on CLHEP 2.0: GC reported a number of inconsistencies in implementation of namespaces, which he had communicated to its editors. The evaluation was that it was not ready for use by G4.
Report from testing & release teams
Sergei report on the current status of testing, involving two migrations: storing of tables and the new particle change signatures. Gabriele reported on the imminent availability of first candidate tag for release.
Issues impacting users
Noted that migration is required for those examples using ‘User limits’ to limit the step size. A new process must be added to the physics list for this: the process takes over responsibility from the Stepping Manager.
Action (future, SoftMan) Evaluate impact of (eventual) migration to CLHEP 2.0 on Geant4 examples and user codes.
Move to new CVS repository
Agreed to move CVS repository no sooner than release 7.0, and prune old/dead directories. To enable move, those accessing the current repository remotely, especially via the pserver on g4cvs, should check that the new system works for them on the test repository. To study whether read-only access to old repository can be arranged simply.
Action (Gunter) to make test repository available for testing and send reminders to category coordinators and developers to test their own access.
Action (Category coordinators / taggers): respond to proposal of dead directories and Gunter know of other directories with are candidates for pruning.
Changes after 7.0
Agreed that migration to ‘non-static’ particle design will be put in place in 2005.
Action (H. Kurashige, M. Asai): Identify impact of change of particle design.
3. Collaboration Agreement
The TSB expressed strong concerns regarding the proposed revisions of the draft Collaboration Agreement (CA), dealing with the potential endorsement of the spokesperson election. Agreed to discuss the matter with CB members, potential at the December Geant4 anniversary event.
Agreed to consider system of voting in collaboration, in order to avoid decisions with small pluralities.
Hans-Peter noted a few additional concerns:
- the asymmetry in the draft regulations, in which larger working groups do not directly elect their coordinator, whereas smaller ones do;
- the absence of the notion of ‘investment’ in the proposed CA.
4. Geant4 10th Anniversary and meeting on Future
Agreed need for video in discussion sessions at LAPP. Endorsed provision of bus from CERN to LAPP for participants on Tuesday, December 14th.
5. Proposals for new Working Groups
Agreed the creation of the Advanced Examples working group.
