                    Review of main policy themes
Oxford University
e-Science Centre

  • Addressing key future ‘Services’
           – Main policy themes this year:
              • Public platforms, RISC decommissioning, LINUX service,
              • Storage
           – Both were started in 2000
           – Both needed many iterations

  • Real advantages of FOCUS
           – Very wide user base represented
           – Forum for services to be discussed by Users and IT

            FOCUS plays important role in facilitating iterative evaluation and
            development, recording steps in the process, and making decisions

                                            12                    HEPCCC 16 Nov. 2001
                        FOCUS -tricky to make process work well
Oxford University
e-Science Centre

  • Model of operation (taken from last year’s talk)
     – Ideally:
                    • Well researched topic, users consulted, groundwork done
                    • Active user participation in process (sometimes through Work
                      Groups), preferably individual taking ownership of issue, reviewing,
                      working with members of IT
                    • Then … brought before the FOCUS committee
                        – Users feel correctly represented
                        – Solution presented which they can buy into
                        – IT department - part of the plans
                        – Request being made to IT viable, and costed
                        – Directors can go away
                            • Understanding and appreciating issue!
                            • Resource implications well defined
                            • Able to convince directorate that correct decision
           – Hard to realize in practice, challenge is to ensure rewarding
             meeting for all attendees
           – Often process has to be iterative

  • Identify issue to be addressed (generally by IT – sometimes by users)
           – Present the issue to FOCUS
              • Often the general future direction is known, but there are too many
                uncertainties to make a decision, and furthermore a certain amount of
                ‘negotiation’ and adjustment is needed

           – Commission User review of issue
              • (The most difficult aspect of the whole exercise is to find a User(s) who
                will represent the whole community)
           – Ask IT to present technical possibilities and recommendations
              • May require waiting for new technologies to develop
           – FOCUS listens to Users and IT proposals and draws conclusions
           – Iterate!

           – FOCUS draws to conclusion, and oversees the implementation
           – FOCUS monitors progress in implementation, (and finally its termination!)

  From last year’s talk…
  • FOCUS is an acronym for Forum On Computing: Users and
  • Taken from Minutes of 1st FOCUS Meeting (14 Mar. ‘96), which in
    turn was quoted from DG’s letter to Manuel Delfino, Feb. 6,
     – “FOCUS will confront the needs of the CERN experiments and the
       present and planned evolution of CERN computing services with a
                    time window extending roughly two years into the future.”
  • The Minutes added:-
           – “The mandate will be implemented by enhancing the communication
             between ‘consumers’ and ‘service providers’ of CERN computing in
             order to arrive at clear definitions of needs and of services.

  Minutes addition stresses the ‘service’ aspect

  • Intentions, not always practice!

           – Always have 4 agendas ahead (differing degrees of detail)
           – Have at least three weeks notice of full agenda before a meeting,
             and as many talks available in advance of the meeting as possible

                              FOCUS from 2002
Oxford University

  • The FOCUS Project life-cycle described earlier has been applied to
    itself ---to explore and develop a revised FOCUS remit!
  • Process started last year (as reported to HEPCCC)
  • 4 bites at the cherry this year
  • Conclusions
           – Important role that FOCUS plays, as borne out through activities in 2001, is
             “overseeing” services provided by IT for experiments
               • Conception of project/service
               • Establishing User requirements
               • Agreeing definition of service after suitable investigation
               • Developing project to point of offering a service
               • Implementation of service
               • Operating service
               • … and finally, concluding the service
  • Future FOCUS operation:-
           – Reduced scope
           – Reduction in membership
           – Reconsider role and operation of the committee at the end of 2002

                    FOCUS Mandate version 2.2
Oxford University

  • Draft text, as under discussion by Committee…
  • “Background:
           – FOCUS’s mandate is changed following the formation of the LHC
             Computing Grid Project Structure.

           – Working assumptions made to determine the revised mandate:
              a. FOCUS’s main role is to look at the implementation, defining,
                running, and ultimately phasing out of services;
              b. As previously, it is primarily concerned with IT services run on
                the CERN site;
              c. COCOTIME maintains control over resources;
              d. HEPCCC retains responsibility for providing ‘a forum in which the
                Directors responsible for Computing at the major European
                Institutes … are able to discuss the organisation, co-ordination
                and optimisation of computing in terms both of money and

                          FOCUS ToR version 2.2
Oxford University
e-Science Centre

  • Draft text, as under discussion by Committee…
           1. FOCUS will normally meet four times a year as a forum for bringing
              together CERN IT providers and users to define and oversee:- the
              commissioning, operation, prioritisation and decommissioning of services; the
              services concerned are primarily those on the CERN site;
           2. it facilitates the agreement of clear definitions of service requirement and
              provision, and monitors quality of delivery;
           3. FOCUS concentrates on generic IT activities which have wider relevance
              than the LHC experiments alone, relate to non-LHC experiments, or
              disseminate developments from the LHC experiments to other areas;
           4. FOCUS reports to the Research Sector Management, and in particular to
              the Director for Technology Transfer and Scientific Computing;
           5. FOCUS plans and operates across a medium range timescale, typically two
           6. its mandate and ToR will be reconsidered at the end of 2002.”

  • FOCUS has been a useful forum, good progress made in 2001,
    policy established, and recorded
           – The themes covered in 2001, as summarised here, show the strong
             emphasis on overseeing services
  • FOCUS will need to evolve to fit around the new LHC Structure
           – This will lead to reduced scope and reduced membership
  • The draft new ToR specify the new emphases for FOCUS
           – It will concentrate on overseeing generic services, supplied by IT for
             the experiments
  • Wide representation will continue to be important
  • There is strong and wide support for FOCUS continuing in this
  • Its mandate and ToR will be reviewed at the end of 2002
  • Greatest urgency now…
           – New chair-person and secretary need to be found quickly!
