DOE Office of Science Data Management Workshop
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 wouldn’t get you tenure.
– Much vigorous and productive discussion

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

Chicago Workshop Goals
•
Discuss and improve the proposed report structure
•
Continue the move from a “laundry list” of needs and topics to wellorganized 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

Straw-man report
09:45 am
View from simulation-driven applications
10:45 am
View from experiment/observation-driven applications
11:15 am
View from information-intensive applications
11:45 am
DOD data-management requirements
1:30 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
4:30 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
08:30 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 crossgroup comparison of cost and priorities.
11:00 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.
1:15 pm
Parallel sessions of application-led groups to prioritize technologies in their
domains.
Groups:
1.simulation-driven applications
2.experiment/observation-driven applications
3.information-intensive applications
3:45 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.
7:30 pm
Group leaders and other volunteers will develop a joint plan on how to normalize the
cost and priorities.
