COSMO-ART users


Philippe Steiner

• Need for clearer rules with the increase of users.

• Easier software maintenance and quality control.

• Insurance of a continued quality of the Software

concerning

• design

• implementation (coding)

• documentation

• testing

• Necessary for COSMO to protect the many operational

uses often related to critical applications

Source code management Motivation


Philippe Steiner

Reference Version

of The Software

Released Version

of The Software

The Idea

(and first development)

Development / Test Versions

of The Software

The Implementation (into an official version)

The Development (of a private version)

Monitor:

• Somethings going wrong?

• Software incomplete?

• New scientific breakthroughs?

Second Management Decision:

• technical requirements fulfilled?

(Technical Test Suite)

• meteorological tests ok?

• documentation available?

Testing by special users:

• COSMO Test Users

• NWP Test Suite

First Management Decision:

• inline with planning?

• needs resources?

Source code management Development process


Philippe Steiner

• Coordination with CLM and ART communities through

participation in their coordinators in the COSMO Scientific

Management Committee

• Policy defined by the COSMO Steering Committee to

consider the input of CLM and ART for reference versions

The STC confirms the importance of these three COSMO applications and the

fruitful cooperation between the respective communities. For accomplishing this

goal it stresses in particular the key role of the common reference COSMO code

and its long-term stability.

Consequently, the ART and CLM communities take part in the source code

management process via scientific cooperation with the respective Working

Groups and via their representatives in the SMC. The STC will thoroughly

consider their opinions while making the final decisions on the reference software.

For functions which are mission critical for CLM or ART, it will be open for

implementing them with ifdefs.
