  1. 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 F. Di Maio, M.Vanden Eynden

  2. Contents • Foreword • CO proposal for FE Software • PS FE software • Inventory • Evolution F. Di Maio, M.Vanden Eynden

  3. 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” F. Di Maio, M.Vanden Eynden

  4. 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 F. Di Maio, M.Vanden Eynden

  5. 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) : • 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 F. Di Maio, M.Vanden Eynden

  6. 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 F. Di Maio, M.Vanden Eynden

  7. 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 F. Di Maio, M.Vanden Eynden

  8. PS Front-end SoftwareInventory • 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 F. Di Maio, M.Vanden Eynden

  9. PS Front-end SoftwareInventory • An excel file (here) with the ABGroup field initialized • To be checked and updated by the groups • Once done → configuration DB F. Di Maio, M.Vanden Eynden

  10. PS Front-end SoftwareInventory Group in charge of the equipment Changes from the DB Number of FECs “Shared” (more than one accelerator) F. Di Maio, M.Vanden Eynden

  11. PS Front-end SoftwareInventory F. Di Maio, M.Vanden Eynden

  12. PS Front-end SoftwareInventory • “specific” classes: only on one accelerator • GM+FESA in the 2007-2010 period • Remark: figures not corrected by removing FESA GM adapter classes F. Di Maio, M.Vanden Eynden

  13. PS Front-end Software Evolution • Phase I • GM->FESA when: • New equipment • New interface • New software required (problems or extension planned) • Renovate equipment and interfaces • Reverse the balance GM/FESA • Phase II • Homogenize / accelerator • Suppress GM I ? II F. Di Maio, M.Vanden Eynden

  14. PS Front-end Software Evolution • Transition I→II to be defined • Phase I : new FESA classes • Phase II: GM-> FESA migration • 0.25-0.5 FTE / FESA class with temporary staff (experience in BI & CO) • Number of FESA classes is not the current number of GM classes F. Di Maio, M.Vanden Eynden

  15. 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 F. Di Maio, M.Vanden Eynden
