This talk is part of the System Research Seminar series
The Open Science Grid (OSG) is a DOE and NSF funded US national distributed computing facility that supports scientific computing via an open collaboration of science researchers, software developers and computing, storage and network providers. The OSG Consortium is building and operating the OSG, bringing resources and researchers from universities and national laboratories together and cooperating with other national and international infrastructures to give scientists access to shared resources worldwide. The particular characteristics of the OSG are to: Provide guaranteed and opportunistic access to shared resources; Operate a heterogeneous environment both in services available at any site and for any Virtual Organization, and multiple implementations behind common interfaces; Support multiple software releases at any one time; Interface to Campus and Regional Grids; Federate with other national and international Grids.
In the talk, we will provide an overview of these two cyber-infrastructures and present the capabilities we implemented and deployed to 'elevate' local GLOW jobs to the national OSG infrastructure. These capabilities support a 'bottom-up' approach to the construction and operation of large scale distributed/grid computing infrastructure.
Dr. Livny's research focuses on distributed processing and data management systems and data visualization environments. His recent work includes the Condor distributed resource management system, the DEVise data visualization and exploration environment and the BMRB repository for data from NMR spectroscopy.
