  1. LCG Applications Area Milestones Torre Wenaus, BNL/CERN LCG Applications Area Manager LHCC Meeting November 25, 2002

  2. Initiation of AA Work via SC2-RTAGS • Applications Area prerequisite and priority for initiating work: • RTAGs successfully addressing common projects • And SC2 turning over project mandates to the PEB-AA • Initial round of project mandates emerged from RTAGs in April • Software process • Persistency framework • Math libraries • Second round emerging now • Architecture blueprint (guidance for all projects; work for several) • Event generators • Detector description • Simulation Translation into AA projects…

  3. Apps Area Project Status • Apr: Software process and infrastructure (SPI) – Alberto Aimar • Apr: Persistency framework (POOL) – Dirk Duellmann • Jun: Math libraries – Fred James • Oct: Core libraries and services (CLS) – Pere Mato • Nov: Physicist Interface (PI) – Vincenzo Innocente • Event generators (Project activity pending) • Detector description (RTAG complete; SC2 deliberating) • Simulation (RTAG complete; SC2 deliberating) Status relative to preliminary plans at March Launch Week…

  4. Top Priorities from March – A Current Look Initiate: First half 2002 • Establish process and infrastructure project (Active) • Address core areas essential to building a coherent architecture, and develop the architecture • Object dictionary (Active) • Persistency (Active) • Interactive frameworks (Launched), analysis tools (Partially launched) • Address priority common project opportunities • Driven opportunistically by a combination of experiment need, appropriateness to common project, and ‘the right moment’ (existing but not entrenched solutions in some experiments) • Detector description and geometry model (RTAG complete; SC2 deliberating) • Driven by need and available manpower • Simulation tools (RTAG complete; SC2 deliberating)

  5. Near term priorities from March • Build outward from the core top tier components • Conditions database (Pending, but common tool exists) • Framework services, class libraries (Launched) • Address common project areas of less immediate priority • Math libraries (Active) • Physics packages (Mandate received by PEB-AA) • Extend and elaborate the support infrastructure • Software testing and distribution (Active) Initiate: Second half 2002 Deliver: fall/late 2002: basic working persistency framework (On schedule)

  6. Medium term priorities from March Initiate: First half 2003 • The core components have been addressed, architecture and component breakdown laid out, work begun. Grid products have had another year to develop and mature. Now explicitly address physics applications integration into the grid applications layer. • Distributed production systems. End-to-end grid application/framework for production. • Distributed analysis interfaces. Grid-aware analysis environment and grid-enabled tools. • Blueprint RTAG recommends prompt attention (RTAG) • Under SC2 consideration • Some common software components are now available. Build on them. • Lightweight persistency, based on persistency framework • Release LCG benchmarking suite

  7. Candidate RTAG timeline from March Blue: RTAG/activity launched or (light blue) imminent

  8. Apps area planning materials on web • Planning page linked from applications area page: in development • Applications area plan spreadsheet: overall project plan • http://lcgapp.cern.ch/project/mgmt/AppPlan.xls • High level schedule, personnel requirements • Applications area plan document: overall project plan • http://lcgapp.cern.ch/project/mgmt/AppPlan.doc • Incomplete draft • Personnel spreadsheet • http://lcgapp.cern.ch/project/mgmt/AppManpower.xls • Currently available/foreseen apps area personnel, activities • Planning materials – PBS, milestones, personnel resources • http://atlassw1.phy.bnl.gov/Planning/lcgPlanning.html

  9. Apps Area Milestones • Level 2 milestones developed for existing and anticipated projects • Except for small projects, not done yet (math libs, generators) • At least until mid 2003 • Milestones in the existing projects have been either defined by or OK’d by the project managers • Project data maintained in XProject (in-house tool for software project planning) • And exported to MS Project for integration with other areas, Gantt display, etc.

  10. Apps Area Milestones • State of the AA milestones reflects the state of the AA projects • L1 milestones are only in project areas which were defined or foreseeable early • Persistency and grid interfaces • Nonetheless, we probably have the right set of L1 milestones, unless our mandate in simulation warrants L1 milestone(s) • L2 milestones are detailed only in the one software development project that has been active for >1 month and has developed a work plan: persistency • Other development projects were initiated in Oct, Nov or are still pending • Will be filling out the L2 milestones and delivering work plans to the PEB+SC2 over the next several months • Detailed milestone descriptions are shown on the web, but not on these slides

  11. L1 Milestones (1)

  12. L1 Milestones (2)

  13. MS Project – Gantt Schedule for POOL

  14. Pool Release Schedule • End September – V0.1 (Released on schedule) • Core components for navigation • “End October” (Nov 15) – V0.2 (Released on schedule) • First collection implementation • “End November” (Dec 15) – V0.3 (First public release) • EDG/Globus FileCatalog integrated • Persistency for general non-ROOT C++ classes • Event meta data annotation and query • End Feb – Interface-complete release • For experiment software integration • Mid Apr – Pre-production release • Feature-complete with respect to June; bug fix release • June 2003 – Public Production Release (L1 milestone)

  15. POOL L1, L2 Milestones

  16. Software Process and Infrastructure Milestones

  17. Core Libraries and Services Milestones

  18. Physicist Interface Milestones

  19. Concluding Remarks • Applications area schedule in rapid evolution as new projects come into scope • Level 1 milestones, set last spring, still seem appropriate and attainable • Their definitions were tightened up as much as possible given present knowledge • And tightening them further as new (e.g. RTAG) info comes in has been built into the schedule • Level 2 milestones establish the detailed program of work and provide project tracking • Granularity ~1/month for the major projects, for ~1yr out; less frequent beyond 1yr • Will be fleshed out for the new projects over next ~2 months
