CPU_POWER_MGMT_(D)

   On Integrity servers, a CPU can be placed in "low-power mode"
   when it is idle. This minimizes power consumption, thereby
   reducing energy costs for the system. Beginning in Version 8.2-
   1, OpenVMS Integrity servers supports this feature based on the
   settings of two system parameters: CPU_POWER_MGMT and CPU_POWER_
   THRSH.

   A value of 1 for CPU_POWER_MGMT means on (the default); a value
   of 0 means off. Whenever the CPU_POWER_THRSH parameter value is
   exceeded, the operating system places an Integrity processor in
   low-power mode if it is idle. OpenVMS Integrity servers does this
   only if CPU_POWER_MGMT is on. A CPU returns to normal power when
   it receives an interrupt.

   CPU_POWER_MGMT is a DYNAMIC parameter.
