Workshop Goals

• Richard P. Mount
• May 24, 2004
• DOE Office of Science Data Management Workshop

2
Workshop Progress (1)

• SLAC DM Workshop, March 2004
• Presentations of application-science needs,
  worries and frustrations
• Presentations of relevant computer science and
  technologies
• Gap between many application sciences and CS
• We need a holistic approach to our scientific
  workflow problems and these CS guys are talking
  about ontologies!
• Gap between what CS is funded/rewarded for
  producing and what the application sciences need
• Proposals for long-term user support and product
  hardening do not get funded and the work wouldnt
  get you tenure.
• Much vigorous and productive discussion

3
Workshop Progress (2)

• Extended Organizing Committee, April 2004
• Application scientists and computer scientists
  searching for, and finding, mutually
  understandable ways to organize the issues
• Workflow diagrams proposed as a good basis for
  comparing and contrasting application science
  needs (in many cases)
• Agreement on a straw-man report structure to be
  presented to this workshop

4
Chicago Workshop Goals

• Discuss and improve the proposed report structure
• Continue the move from a laundry list of needs
  and topics to well-organized programs of work
  reflecting application-science priorities
• Workflow diagrams may help in this organization
  of ideas
• Aim to make a case at the Program of Funding
  level, the WBS level can be used for illustration
• In other words, avoid commercials for
  particular CS approaches to solving a problem
• Application-science priority means we would be
  prepared to contribute to this work with our
  BES/BER/FES/HEP/NP
• Propose approaches to funding and program
  management that exploit this mechanism (e.g.
  SciDAC?)
• Priorities will change the approach should
  still work
• Address the gap between academic CS and the need
  for robust software with 20-year support
• Funding and program management mechanisms that
  support what is needed

Workshop Structure
Monday May 24 Monday May 24
0915 am Straw-man report
0945 am View from simulation-driven applications
1045 am View from experiment/observation-driven applications
1115 am View from information-intensive applications
1145 am DOD data-management requirements
130 pm Technology Working Groups Groups to address a) additions, corrections and refinements to the report, and b) gaps, cost, priorities and classification into development/hardening/deployment categories. Groups 1. Workflow, dataflow, data transformation 2. Storage, data movement, grid, networks 3. Metadata management and cataloging 4. Efficient access and query, data integration 5. Integrated data Analysis, visualization
430 pm Panel Discussion on Workflows Make progress towards a common approach to describing workflows such that commonalities and true differences are clear.

Workshop Structure
Tuesday May 25 Tuesday May 25
0830 am Group Leads will report back to the general session, summarizing their group discussion. This will be followed by open discussion. This should lead to cross-group comparison of cost and priorities.
1100 am Panel on a management plan - an effective process to direct funding to benefit the various application domains. This is the plan that should get DOE application offices (other than OSCAR) interested and involved.
115 pm Parallel sessions of application-led groups to prioritize technologies in their domains. Groups simulation-driven applications experiment/observation-driven applications information-intensive applications
345 pm Brief summary reports from application-led groups. Followed by a panel session to come up with a prioritization and cost for the development/hardening/deployment of SDM technologies.
730 pm Group leaders and other volunteers will develop a joint plan on how to normalize the cost and priorities.
