VMS Help Sys Parameters, LCKMGR_CPUID  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    (Alpha only) The LCKMGR_CPUID parameter controls the CPU that the
    Dedicated CPU Lock Manager runs on. This is the CPU that the
    LCKMGR_SERVER process will utilize if you turn this feature on
    with the LCKMGR_MODE system parameter.

    If the specified CPU ID is either the primary CPU or a non-
    existent CPU, the LCKMGR_SERVER process will utilize the lowest
    non-primary CPU.

    For more information, see the LCKMGR_MODE system parameter.

    LCKMGR_CPUID is a DYNAMIC parameter.
