Create a platform for 21st Century Science Provide a framework for science experiments to focus and encourage E & O efforts Utilize “the grid” to:

An NSF-funded collaboration Goals:

Increase compute power Increase collaboration Provide access to huge datasets (Uses range from compute resources to meta-data)

Data sharing Workflow management “Publishing” of results Discovery of others’ data products Access to “canned” analysis recipes

The vehicle to do this: e-Labs and i-Labs They allow:

Cosmic Rays

Existing e-Labs: Production:

Access to data from nearly 100 classroom detectors > 9000 “detector days” of data (flat “raw” files) > 200 user accounts many with data uploads

CMS (Calorimetry test beam) AMELIA (ATLAS event reconstruction) LIGO (Access to environmental monitors) STAR (RHIC experiment event reconstruction)

e-Labs Infrastructure:

Cosmic Ray e-Lab Data Analysis CMS e-Lab uses ROOT for the analysis routines

Each DAG node is a smallish perl script Intermediate data files are input for the next node Analyses are pre-defined workflows

Nearly 300 users (mostly in US High Schools) 103 saved data products 105 derived data products (18 months)

Tomcat interface to ROOT Working to create SWIFT interface to ROOT

Summary

e-Labs use the VDS API to allow students access to data and pre-defined analysis workflows. Computes run on a smallish cluster at Argonne National Laboratory. We have executed some jobs on OSG compute resources but have not put this in production. We have users! We are developing an e-Lab interface for ROOT. Supporting end-users is a DC effort.
