Torre Wenaus, BNL/CERN
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…

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…

Torre Wenaus, BNL/CERN
Top Priorities from March – A Current Look
1. Establish process and infrastructure project (Active)
2. 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)
3. 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)
Initiate: First half 2002

Torre Wenaus, BNL/CERN
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)

Medium term priorities from March
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
Initiate: First half 2003

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.

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

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
