OGF eScience Function

This document discusses the four major types of eScience activities, including group activities, timely community activities, long lead time single track workshops, and software development track sessions. It also highlights the users and grid projects involved in building grids and showcases current workshop topics and best known methods (BKM).

  2. Four major types of eScience Activities • Group activities such as those in GIN (Interoperability) • Groups perform long term activities in focused areas • Typically does not get much high level visibility except for GIN • Note two new groups in Education and Reliability • Typically one or more distinct 90 minute sessions • Timely community activities arranged in the three-five months before meeting and including panels, tutorials and short workshops • Current submissions to community program • Typically one or two 90 minute sessions per submission • Long lead time single track workshops with invited and contributed presentations in topics of broad interest to OGF. • Typically 4 or 5 90 minute sessions • Refereeing similar to high quality conferences • Software Development Track starting at OGF19 • Total 8-12 90 minute sessions at OGF19 2

  3. Software Development Sessions Users Grid Projects • Grids are built from services which hopefully respect standards • However there are several building blocks or subsystems like Globus or SRB which are used in many Grid projects • TeraGrid EGEE Geon LEAD MyGrid China National Grid Naregi are Grid Projects • Form initially at least de facto standards • What is OGSA in the “non Green Field” of existing subsystems? • OGF will offer “user group” sessions in “Grid Subsystems” in a set of consecutive sessions aimed at those building Grids and not at people using Grids • OGF can provide one-stop shopping so don’t need to attend XYZweek for all XYZ • GIN-Standards Interaction? Grid Subsystems Grid Services 3

  4. OGF19 Software Development Track • We have invited (so far 8 acceptances) in alphabetical order • Condor Scheduling system • Genesis II OGSA Grid Infrastructure • Globus core Grid infrastructure • Grid-Shib Grid security • GridSphere portlet container for portals • NWS and BQP Network/Queuing Tools (Rich Wolski) • OGCE Open Grid Computing Environments collection of portlets (for Science Gateways) • OMII core Grid infrastructure • SRB data Grid infrastructure • Unicore core Grid infrastructure • Will repeat at OGF20 (UK) but less time available Less widely adopted software could be showcased in community program 4

  5. Current Workshop Topics • Federated Identity at OGF19 organized by Ken Klingenstein and Satoshi Matsuoka • Semantic Web 2.0 at OGF19 organized by Dave de Roure • Probably CommercialWeb 2.0 at OGF20 organized by Charlie Catlett • Preferred organization of one –day workshops • Invited and Contributed Talks • Panel aimed at summarizing topic as relevant to Grids or Grid technology • After meeting one would • Post presentations • Convert panel discussion into a “review” “synopsis” or “BKM (Best Known Methods)” for area covered • Possibly arrange for scholarly publication for follow-up papers 5

  6. BKM: Best Known Methods? • There are many grids and experience building and using them. These use “standard” software packages supplemented by more or less “local” work • BKM’s, Status reports, Summaries, Reviews presumably capture current understanding of research, practice and experience • These consist of • Integrated reviews and/or • Broad collection of articles such as sets of papers at a focused meeting • Provide a set of links organized by say OGSA categories if possible which link to BKM’s which may or may not be OGF Generated • Portals, Workflow, Science Gateways were covered in OGF workshops 6

  7. Community Program Users Grid Projects • Community oriented activities with relatively light weight approval process with call 3-5 months before meeting and decisions 2-3 months before • Joint between Enterprise and eScience • Exploratory (Birds of a Feather) sessions that could leads to groups or full one-day workshops • Tutorials but not well done in OGF as no thoughtful coordination and don’t easily attract Grid users (as opposed to Grid builders) • Need to establish a track with a uniform audience like we have for software development • Small workshops often led by groups such as OGF19 Grid Reliability and Robustness 2 session workshop Grid Subsystems Grid Services 7
