Report from other meetings (J.Apostolakis)
Collaboration agreement still in discussion (see next point)
CB expects input from TSB regarding the proposed CA (see next point)
G4 delta review
Final report is expected after the final report of the Simulation RTAG.
Future Collaboration Agreement (J.Apostolakis)
a sub-group will be created with the following mandate
We convene the sub-group and request it to agree upon and
- Provide a set of requirements for a Collaboration Agreement
* necessities, i.e. fundamental
requirements to be satisfied by a CA,
* questions to be answered by
using as one starting point the pros/cons drafted by the first sub-group
inviting inputs from the members of Collaboration Board(CB), the TSB,
(appropriately) other active developers.
- Build a proposal based on these requirements, and
* examining the current MoU and
CA proposal(s) to identify compatible
* creating new elements to addresses
and fulfill the remaining
In order to obtain as wide agreement as possible in the TSB and the
collaboration as a whole, this sub-group will be requested to
- Obtain input from TSB members and developers;
- Communicate progress regularly, including
- Provide the draft resolutions to the TSB in a timely, regular
- Solicit feedback on drafts from TSB members, and at appropriate
checkpoints, from the CB and the collaboration at large.
Potential first targets for deliverables:
- Advanced Draft of Requirements:
5th December 2002
- Draft of Elements of future CA:
19th December 2002
Note these appear to be very ambitious targets, and are likely to be
challenging to achieve. However demonstrable progress is vital, and
time constraints exist.
New G4Scintillator process will be part of the December release
9 of the 11 milestones of hadronics were met at the time of this tsb meeting,
with 1 more to be expected with the 5.0 release.
two new cascade tools introduced
Kinetic model is ready to be released. It is renamed the binary cascade.
update of data bases
development of Internal Conversion
advanced examples will be part of system testing.
release platforms (G.Cosmo)
Linux: redhat 6.1 and 7.3 with gcc 2.95.2
Sun : cc 5.2 aand 5.3
cuts per region
available for alpha users end January 03.
It is agreed that changes to the Run Manager are not yet decided: feedback
are required before final design.
There will be no change before convergence of feedbacks.
It is agreed to build global libraries in debug mode for releases and patches.
G4 Delta Review Followup
V.Ivantchenkio made some suggestions:
physics lists could be built by type of physics instead of by particles
to organise a workshop on hadronic physics: experts would have the opportunity
to meet experiments.
Category coordinators and Architecture group should give feedback on recommendation
Launching the 2003 Requirements round
Experiments should send their requirements before the January TSB meeting.
most probably 16 January 03.
