Managing host power states

LSF energy aware scheduling host power state management enables automatic workload driven power management policies for hosts in an LSF cluster. LSF can power on hosts as jobs need them, and take appropriate power management actions as workload changes. Power management policies support the power management features of xCAT version 2.7.

LSF administrators can set cluster-wide power management policies, and manually manage the power characteristics of specific LSF hosts. Multiple power management policies can also be configured with time windows to manage the power state for specified hosts and host groups automatically.

Cluster administrators can retrieve and monitor the power state changes of specific hosts and view power state of each host, along with the configured power management policy definitions.

System requirements

Host power management for LSF energy aware scheduling has the following requirements:

  • All compute nodes have P-States and C-States enabled.
  • All LSF master and master candidates must be clients of a provisioning management system, which is able to call corresponding provisioning tool command line to connect with its management node directly.
  • xCAT v2.7 or higher should be ready to use for LSF server hosts management
