Sun Grid Engine 6.2ut Add-on Manages Shared Resources

The nature and functions of Service Domain Manager (SDM), an add-on component for Sun Grid Engine 6.2u5, are described in DanT’s GridBlog. He writes that SDM is designed to allow for services of all types to share resources with each other. He explains that each cluster has a set of performance metrics specified via service level objectives (SLOs). If at any point a cluster is in violation of its SLOs, it appeals to the SDM resource provider service for additional resources. The resource provider will look for resources wherever they’re available and, finding them, will re-assign the resources to the cluster in need.
