Green Computing

PBS Works is a pioneer in energy efficient computing – from our first Green Provisioning solution in 2008 to custom power management capabilities with leading hardware providers.
Keeping infrastructure affordable and efficient has always been a key requirement for HPC implementations. As every aspect of HPC grows larger and more complex (from data size to hardware footprint), energy conservation and minimizing operating costs have become increasingly important factors shaping how HPC resources are used today.

PBS Professional’s Green Provisioning™ can monitor, shutdown and restart high-performance computing (HPC) systems based on the user’s requirements, ultimately managing power consumption to reduce energy usage. Validated by several large scale customers, Green Provisioning has lowered their energy use by up to 30 percent.

“The amount of computing power necessary to conduct our research is enormous, so we needed a solution that allowed us to fully utilize our processing power. The strength of the solution and Altair’s recognized leadership in the life sciences industry made the selection of PBS Pro an easy choice.”

Data centers are growing at a tremendous rate, but energy costs are quickly becoming a proportionally higher part of most IT operations budgets. Today, energy costs – to power and cool systems and data centers – consume the largest percentage of operational budgets.

Scalable and resilient to support thousands of compute nodes and limitless jobs, our Green Provisioning offering saves a significant percentage of power and cooling costs for your computer systems.

Features and benefits of PBS Works Green Provisioning™ include*:
  • Dynamic system monitoring: Monitors the state of the queues and the level of activity on each node to decide if nodes running no jobs can be powered down or if queuing jobs require powered down nodes to be booted up.
  • Customizable power reduction methods: The mechanism to adjust power use can be customized to suit the computing environment. Throttle CPU frequency to minimize idle power consumption, or fully shutdown nodes to eliminate consumption entirely.
  • Node power down priorities: To ensure the highest performance nodes are available as much as possible, System Administrators have the ability to prioritize which nodes should be powered down first by assigning a “power down priority” to each node.
  • Node power cycle time delays: Each node in the system has its own parameters that control how long the node is idle before it is powered down and how long to wait for the node to boot up.
  • Temperature-based placement: Schedule jobs to nodes based on temperature to reduce cooling costs by evenly spreading out the A/C loads.
  • Custom resources are supported: Fully supports node-level custom resources. When working out which powered down nodes should be booted up, the custom resources requested by each queued job are matched against the resources available on each node.
  • Multi-node jobs are supported: Fully supports jobs that request multiple nodes or multiple chunks
  • Greater control and flexibility in managing energy usage: PBS Professional 13.0 will add support for per-job power profiles, overall power caps, and energy accounting
