GriPhyN / iVDGL Develop the technologies & tools needed to exploit a distributed cyberinfrastructure Apply and evaluate those technologies & tools in challenging scientific problems Develop the technologies & procedures to support a persistent cyberinfrastructure Create and operate a persistent cyberinfrastructure in support of diverse discipline goals

Sphinx Scheduling on a grid has unique requirements –Information –System Decisions based on global views providing a Quality of Service are important –Particularly in a resource limited environment Sphinx is an extensible, flexible grid middleware which –Already implements many required features for effective global scheduling –Provides an excellent “workbench” for future activities! VDT Server VDT Client ? Recommendation Engine

CAVES & CODESH Concentrate on the interactions between scientists collaborating over extended periods of time Seamlessly log, exchange and reproduce results and the corresponding methods, algorithms and programs Automatic and complete logging and reuse of work or analysis sessions (between checkpoints) Extend the power of users working or performing analyses in their habitual way, giving them virtual data capabilities Build functioning collaboration suites (stay close to users!) First prototypes use popular tools: Python, ROOT and CVS; e.g. all ROOT commands and CAVES commands available
