Moab Adaptive HPC Suite changes a node’s operating system on the fly in response to workload needs. As an intelligent metascheduler, Moab determines when the OS mix should be modified for optimal efficiency, based on defined policies and service-level agreements and on current and projected workload. When specified conditions are met, Moab automatically triggers the OS change using a site’s preferred OS-modification technology, such as dual boot, diskful, or stateless (diskfree) provisioning, or virtualization (using Hyper-V within Windows HPC Server 2008, VMware, or XenWare). |
