Open Science Grid (OSG)
Rob Gardner and Mike Wilde, PIs
Goals: The Open Science Grid (OSG), which
initially began with joint efforts from the GriPhyN,
Particle Physics Data Grid, and the iVDGL
projects, is a production-scale, shared
cyberinfrastructure built through a applicationdriven,
multi-disciplinary science consortium.
The middleware infrastructure is built from the
Virtual Data Toolkit (VDT) which packages and
integrates software from Globus, Condor, and
suite of virtual data services developed by the
GriPhyN project. The vitual organization
stakeholders include communities from high
energy physics, gravity wave physics, genomics,
brain imaging research, and computer science
among others.
Significance: The UC/CI group has played leadership roles in several activities of the OSG, including education and outreach, consortium governance, and the OSG Integration Testbed (ITB). The ITB provides a platform for preproduction service validation, service integration, and application validations over the OSG software stack. The contributions, coordinated by UC, come from a dozen or so external sites and Virtual Organizationss (VOs) which together address a wide range of middleware-site fabric integration issues in a hetereogenous environment. Rob Gardner, pictured here, has played the key leading role on this and the next two projects discussed (TeraPort and the Midwest Tier2 center).
Accomplishments: The UC group has provided a framework for OSG service release specifications, validation procedures, introduction of new services into the OSG computing environment, and site functional testing through deployment of a development and integration cluster with comprised of compute, storage and OSG-edge service nodes.
