A Mixed Windows–Linux Cluster Solution

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.

Moab Adaptive HPC Suite enables maximum resource utilization and increased ROI for both new and existing clusters. The hybrid-OS cluster model also consolidates administration and centralizes job submission across OS platforms. Administrators can easily manage the policies and workload for multiple OS environments using Moab’s unified console. Moab can also make the dual-OS nature of the cluster transparent to end users by applying application and workload information that ensures jobs run on the correct OS without the need for users to specify an OS. Moab can manipulate, grow, and shrink allocated resources to meet service-level targets.

benefits

• Leverage your HPC infrastructure more efficiently as a single, unified resource free from restrictive and costly resource silos
• Simplify the use and management of mixed-cluster environments with a unified interface and automated service-level enforcement
• Balance resource usage between OS environments and respond to workload surges and resource failures with dynamic adaptation of the OS mix
• Schedule automatic reallocation based on workload requirements and established policies
• Automate full business processes that include both Windows and Linux applications
• Tune and reserve the future OS environment mix based on scheduled activities and historical usage patterns

Capability	Windows	Linux	Moab	Advantages
Adapt OS Mix to Meet Workload Needs				Adapt an OS environment to meet the workload needs and mission objectives of an organization. Handle adaptation of OS mix for resource failures, workload surges, service level guarantees, resource reservations, balancing purposes, and etc.
Enable Multi-OS Business Processes Workflows				Enable more automated business processes through automating event-driven workflows that cross multiple OSes. Example: Process data on Linux and visualize the results on Windows as part of a Moab integrated workflow
Unify Job Submission				Submit jobs via a single web submission interface; Moab applies them to the appropriate OS environment
Unify Workload Management & Reporting				Manage workload on both OSes through a single cluster management & helpdesk tool & utilize unified reporting
HPC Resource Manager				Windows’ HPC solution includes resource management; Cluster Resources provides TORQUE* Resource Manager for Linux
System Monitoring Tools				Both OSes and TORQUE provide valuable hardware monitoring
Message Passing				Both OSes include Message Passing Tools
Operating System				Windows and Linux; any OS can be used
