TOPICS AND ORGANISATION OF A DAY

The workshop will be organised around lectures about the code, general principles of phasing and maintenance together with practical exercises, where participants can try in practise what they have heard during the lectures. There will be significant time allocated to free discussions, where strategic questions and remaining practical problems can be informally discussed and solved.

The following daily schedule is proposed:

Morning	: General presentations (powerpoint)
Afternoon	: Practical exercises
Evening	: Free discussions

The following main topics are envisaged:

- Main configurations of ARPEGE/ALADIN: data flow, organisation of the code.
- Phasing in Toulouse, main principles, concepts.
- Possibilities and conditions of remote phasing.
- Export versions, how to use them?
- Creation of prototype export version.
- Local implementation of the ALADIN code.
- Observational Data Base.

Preliminary subjects for the free discussions:

- ALADIN model core documentation.
- Optimization (OpenMP, LSPLIT, continued diagnostics of vectorization/memory).
- Model evolution towards more modularization.
- Strategy for ARPEGE/ALADIN phasing (continue to work out the "2-stage" phasing, with the non-observation part first (=the model),
  and the observation part second. a 1 month delay between the two is roughly speaking optimal).
- Considering the increasing number of configurations (some in the core of the model, some as external combinations via scripts).
  Is a specialization of the code experts necessary, and if yes, how?

Documentations and powerpoint frames are planned to be distributed at the beginning of the workshop.
