BMI Condo on the Owens Cluster
"Condo model" refers to an arrangment when a client leases one or more compute nodes for the shared cluster while OSC provides all infrastructure, as well as maintenance and services. BMI's Condo on the Oakley Cluster is leased by the Biomedical Informatics Institute at The Ohio State University. This condo is a temporary "bridge" condo to server the community needs until the Owens Cluster is available.
