SYSMANHELP.HLB  —  Sys Parameters, CPU_POWER_THRSH_(D)
    On Integrity servers, CPU_POWER_THRSH is a parameter expressed
    as a percentage. OpenVMS Integrity servers monitors how active
    each CPU is over a fixed time period. If CPU_POWER_MGMT is on
    and a CPU is idle for a period of time indicated by CPU_POWER_
    THRSH, the CPU is placed in a low-power mode if it is idle. A CPU
    returns to normal power when it receives an interrupt.

    For systems supporting real-time operations that require quick
    response time, HP recommends that this feature be turned off. Use
    of this feature can result in a small performance degradation.

    For more information, see the Intel IA-64 Architecture Software
    Developer's Manual, Volume 2: IA-64 System Architecture.

    CPU_POWER_THRSH is a DYNAMIC parameter.
