Abstract

The Open Science Grid (OSG) ties together individual experiments' computing power, connecting their resources to create a large, robust computing grid; this computing infrastructure started primarily as a collection of sites associated with large HEP experiments such as ATLAS, CDF, CMS, and DZero. In the years since, the OSG has broadened its focus to also address the needs of other US researchers and increased delivery of Distributed High Through-put Computing (DHTC) to users from a wide variety of disciplines via the OSG Open Facility. Presently, the Open Facility delivers about 100 million computing wall hours per year to researchers who are not already associated with the owners of the computing sites; this is primarily accomplished by harvesting and organizing the temporarily unused capacity (ie opportunistic cycles) from the sites in the OSG. Using these methods, OSG resource providers and …
