2 Enable High-Level Problem Solving Environments zTools to enable scientists to compose solutions from a set of building blocks zSeamless access to remote resources zEnabling infrastructure yFramework standards and interfaces yImplementations of reusable components yData object conventions zCandidate for SSI effort

3 Frameworks zInteroperable tools for writing an application yCCA is just a beginning in that direction zLevel above libraries zEnd-user is the application developer zImportant to include reference implementations yexample application built using the framework tools yallows testing of framework installation zDOE 2000 and SSI

4 Reusable Components (Continuing DOE 2000) zSeparable, hierarchical ensembles zCommunication libraries yintrasystem, intersystem, parallel I/O zNumerical libraries ylarge scale - high performance zScientific visualization libraries yremote visualization support; shared viz./VR support zSecurity function libraries zContinue to identify key applications and tools they need (DOE 2000/SSI)

5 Common Data Objects zHelp share data among tools, people, machines ySelf-describing data structures, HDF, NetCDF (or) yStandard representations, e.g., XML, LDIF yData representation conversion capabilities yMove toward unique universal identifiers zCore set of common objects yObjects used frequently in DOE 2000 apps. and tools yEx: compute resources, certificates,...

6 Common Data Objects (cont.) zDOE 2000 work yStandardized objects specific to Collaboratories yData representation designs zSSI opportunities yCommon/self-describing data structures zCollaboration opportunities with other agencies yFacilitate access to and interoperability with digital libraries and archives yTrack developments of other projects, e.g., NASA IPG, NSF

7 Large Data Objects zData management issues for very large objects yTransport of large data sets and objects yHiding of (tertiary) storage yLookup capabilities zDOE2000 foci yNeed methods for both small and large objects zSSI may need this capability yLarge simulation datasets yVisualization output

8 Quality of Service zEnd-to-end performance assurance for applications yNormally thought to be network bandwidth, but also CPU and storage resources yProvide an easy interface for applications to use QoS yTools so adaptive applications can modify behavior zDebugging and monitoring capabilities zMostly a new area for DOE 2000 efforts zThese capabilities useful to SSI, DOE/DP (ASCI), others

9 Collaboration Environment zImportant to any large, distributed project zSupport of interactivity continuum yeasy progression... xfrom low level interaction (MOO, IRC, ) xto mid-level (voice, shared viewers, whiteboard) xto high level (video, app. sharing, screen sharing, shared viz.[SSI]) zNeed single login for all DOE 2000/SSI capabilities zShare information between all tools

10 Collaboration Environment (cont.) zCollaboration agents yactivity monitor ycontact, filtering, event notification yrecording and replay zSupport for asynchronous interaction ynotebooks and data archives (ongoing) yrecording and replay (emerging) yfacilitated search/retrieval (emerging) yversioning (new)

11 Collaboration Environment (cont.) zApproach: low threshold for entry ybase functionality with minimal installation yeasy installation of additional capabilities ysession management and directory services yweb-based view of collaborative activities zRemote interaction with resources (instruments, compute resources, databases, compilers) zProject management (SSI addition)

12 Outreach and Support zAnnounce available capabilities yprovide discovery service (web) zCritical to support initial users yfoster component reuse yeasy to install, well documented zEnable quick success - does something fast zOpen Software approach (when appropriate) yallow users to contribute to the maintenance [Not every innovation has an immediate use. We’re not a large community.]

13 DOE 2000 Testbed Applications zBuild relationships with application efforts zReal use of Collaboratory and/or ACTS tools yestablish an initial user base (for feedback) yhelp validate and steer tool R&D ylearn deployment and support requirements youtreach to scientific community zHelp connect DOE 2000, ESnet, and other research programs zComplement SSI applications areas
