1. Nov, 30 2006F. Di Maio, M.Vanden Eynden1 CO Proposal concerning AB Front-End Software Responsibilities First detailed proposal based on the global Front-end proposal presented at CO3 on Nov 2, 2006

2. Nov, 30 2006F. Di Maio, M.Vanden Eynden2 Contents Foreword CO proposal for FE Software PS FE software Inventory Evolution

3. Nov, 30 2006F. Di Maio, M.Vanden Eynden3 Foreword Four aspects to agree @ CO3 concerning Front-ends responsibilities FE Software (this presentation) FE Hardware (in progress …) FE Configuration Management (not started) FE First-line Responsibility (not started) A clarification towards a department wide strategy rather than a “Big Bang”

4. Nov, 30 2006F. Di Maio, M.Vanden Eynden4 CO Proposal for FE Software CO Responsibility System Level SW O/S definition, installation, support and evolution (LynxOS and LINUX SLC-x) Device drivers and libraries for the list (to be reviewed @ CO3 …) of standard/generic HW modules (CTR-x, GFAs, DAC, ADCs, MIL-1553, WorldFIP, RS-232 line drivers, OASIS boards, etc) Clear commitment from CO to keep strong homogeneity and to offer a complete and well supported set of generic FE controls solutions

5. Nov, 30 2006F. Di Maio, M.Vanden Eynden5 CO Proposal for FE Software CO Responsibility FESA Framework Specification, design, release (up to 3/year) and support of the framework, with full validation @ CO3 level Strong support to developers during all development phases (fesa-support@cern.ch) :fesa-support@cern.ch Training: regular tutorials and hands-on for new developers Design and coding: advice on implementation issues Commissioning and quality insurance: code reviews, correct framework usage, etc (non-mandatory) Operation: strong diagnostic tools and on-line support during normal working hours Strong commitment from CO to develop and offer extended support for FESA, as the agreed AB department front-end solution

6. Nov, 30 2006F. Di Maio, M.Vanden Eynden6 CO Proposal for FE Software CO Responsibility FESA Software Software for the support of the list of standard/generic HW modules Projects under full CO responsibility (BIC, OASIS) Legacy GM Software Classes under PS/CO responsibility only Maintenance limited to corrections and adaptation (environment changes), no evolution. Deployment of new instances CO remains responsible for the development and support of a significant amount of generic and project-based Front-end software

7. Nov, 30 2006F. Di Maio, M.Vanden Eynden7 CO Proposal for FE Software Equipment Groups Responsibility FESA Software Develop software for the support of their specific hardware and instruments Decide, in agreement with AB-OP, about the operational deployment of their software Use CO support during all phases of development Legacy GM Software Replace with new FESA software when required (cf. next slides) Equipment groups are responsible for the development and operation of their front-end software

8. Nov, 30 2006F. Di Maio, M.Vanden Eynden8 PS Front-end Software Inventory Source is the configuration DB Each class: A description A creator (the initial author) An “ABGroup”: the group in charge of the equipment. To be updated All instances (FEC, accelerator) Note: GM adaptor classes can be identified

9. Nov, 30 2006F. Di Maio, M.Vanden Eynden9 PS Front-end Software Inventory An excel file (here) with the ABGroup field initializedhere To be checked and updated by the groups Once done → configuration DB

15. Nov, 30 2006F. Di Maio, M.Vanden Eynden15 Conclusion A practical proposal (clarification) for Front-End software responsibility and support An inventory of the PS Front-End software and its possible evolutions Feedback from each equipment group (CO3) is the next step towards a global agreement, especially concerning the PS complex Next aspects to address: Front-End Hardware Front-End configuration management Front-End first-line of responsibility
