Tasks in 2011

WP11-ITM-IMP12-ACT1: Integration, support and maintenance

Description
This activity concerns all the IMP12 codes, modules or packages at a mature stage. As a minimum, a working Kepler actor (or a suite of Kepler actors) must have been made available during WP10, i.e. corresponding to Phase III (K) of the release cycle (see Appendix A).
Scope of this activity is integration of IMP12 modules and support for code integration in selected workflows, in conjunction with other IMPs. The activity also covers continued maintenance of mature IMP12 codes.
As a guideline, it is foreseen that IMP12 codes under this activity will participate in the construction of the following workflows:

• A workflow coupling ETS, a fixed boundary equilibrium code, and physics modules from several IMPs, aimed at plasma core simulations.

• A prototype workflow coupling the ETS with a free boundary equilibrium code.

• A prototype workflow coupling a free boundary equilibrium code with a feedback controller.

Participants under priority support are expected to provide the code and user documentation, as an integral part of the code release.

The deliverables for 2011 are:

• integration of mature codes into workflows, especially into ETS workflow
• code documentation (phase IV(N))
• physics description of code (phase IV (O))

WP11-ITM-IMP12-ACT2: Adaptation of IMP12 modules and standalone packages

Description
This activity concerns the adaptation up to the stage of tested Kepler actors (phase III(K) of the release cycle of all the IMP12 codes, modules or packages still at a development stage. In most cases, it involves continuation of WP10 work. It may include newly proposed work matching the TF remit.

The deliverables for 2011 are:

• porting of code to the ITM Gateway, test runs and report
• adaptation of code to ITM standard, with use of relevant CPOs, in standalone form; test runs and report
• generation of Kepler actor of code; test on the ITM platform and report

WP11-ITM-IMP12-ACT3: Verification and validation of IMP12 codes

Description
Verification and validation (V&V) is an essential part of the ITM TF code release cycle. This activity targets IMP12 codes qualifying for Phase III (K), to carry out V&V on the ITM platform, employing Kepler workflows. This is a cross-project activity targeting code developers as well as experimentalists to cooperate in the validation work.
The following are minimal objectives for WP11, although contribution to code validation is sought for all IMP12 codes qualifying for Phase III (K).

• Continued validation of the EQUAL equilibrium reconstruction code on JET data.

• Verification of equilibrium and MHD stability codes by code-code comparison within the equilibrium and stability chain and assessment of code inter-operability

The deliverables for 2011 are:

• Validation of code EQUAL on JET data. Report on validation conforming to the ITM validation procedure.
• cross verification of codes belonging to the equilibrium and MHD stability chain
• Report on benchmarking exercises: cross verification of the triplet of high resolution equilibrium codes (HELENA, CHEASE, CAXE), and cross verification of the (ILSA, KINX) pair of stability codes, by code replacement in the Kepler equilibrium and stability chain.

WP11-ITM-IMP12-ACT4: Exploitation of mature workflows: from equilibrium reconstruction to MHD stability analysis

Description
The aim of this activity is the exploitation of the extended chain of equilibrium reconstruction to MHD stability analysis on data from selected experiments for which machine descriptions, data mappings and a suitable shot range is made available (EDRG-ACT1,2).
Specifically, the TF seeks a partnership with one or more Associations (providing suitable manpower) to adapt, when necessary, and to exploit the equilibrium reconstruction and stability chain to carry out an extensive MHD analysis of a significant set of shots, of high relevance for the Association work programme.

The deliverables for 2011 are:

• Equilibrium reconstruction, MHD chain stability chain and public ITM database of relevant shots of device.
• MHD analysis of the selected data base. Report on study.
