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.

Easing the Transistion from Traditional Grid Computing to the Cloud

Ease the transition from traditional grid computing to cloud computing with Sun Grid Engine (SGE) 6.2 Update 3, which features a Service Domain Manager (SDM) Cloud Adapter that provides an interface to manage Amazon’s EC2 Amazon Machine Images (AMI). It also features Initial Power Saving support that uses the existing features of the Service Domain Manager to extract information about the ideal size of a cluster according to demand. The ability to flexibly add execution hosts as needed on demand delivers power and cooling cost savings.
