• Prescott– Co-organised the Boston OSG

Technical Workshop– US-CMS Production Manager

• Rodriguez– Deputy Coordinator for iVDGL– Deployment Board Co-chair for

OSG• KIM

– Project Lead for GridCAT

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!

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

Grid-enabled Analysis Environment

Grid3

• Task Force– Rodriguez member

CMS Computing

• UF Coordinates the US-CMS Production Effort

• Over the past year, Prescott oversaw and was responsible for – 40% of the global CMS detector

simulation– 25% of the global CMS event

digitisation

• Prescott also assists in publishing the MC data to the FNAL Tier-1 and the UF Tier-2 sites

• Effort started in 2001 (pre-grid) with Bourilkov and Rodriguez– Produced all phases, including PU
