Open Science Grid (OSG) is a consortium that enables many scientific breakthroughs by providing researchers with access to shared High Throughput Computing (HTC) compute clusters in support of large-scale collaborative research. To meet the demand on campus, Georgia Institute of Technology (GT)’s Partnership for an Advanced Computing Environment (PACE) team launched a centralized OSG support project, powered by Buzzard, an NSF-funded OSG cluster. We describe Buzzard’s unique multi-tenant architecture, which supports multiple projects on a single CPU/GPU pool, for the benefit of other institutions considering a similar approach to support OSG on their campuses.
