About Energy Aware Scheduling (EAS)

LSF offers energy-aware scheduling features for large-scale LSF installations, where the energy requirements for operating large systems are becoming a significant factor in the overall cost of these systems. On Large systems with either a long lead period to full production or widely fluctuating workloads many nodes can sit idle for significant time periods. The energy-aware scheduling features of LSF enable administrators to control the processor frequency to allow some applications to run at lower frequency with minor performance degradation. This can lead to overall power savings. Conversely, minimizing the frequency on unused cores can also enable maximum turbo boost to active cores, to increase application performance, and reduce run times. Frequency control allows an organization to balance performance with power savings.

The LSF energy-aware scheduling features include the following:
