Grid engine technology is currently used to power thousands of grids, collections of network-connected servers, providing more efficient use of computing resources. The N1 Grid Engine 6 software, the newest version of Sun's resource management solution, includes the core services for establishing and managing a grid environment, and provides policy-based workload management and dynamic provisioning of application workloads for increased productivity. This article discusses abstracting collections of resources within the N1 Grid environment using cluster queues and host groups, and explains how these features can be used to simplify administration and implement scheduling policies.
