/CPU
       /NOCPU [=(x[,...])] (default)

    In multiprocessor configurations, selects the CPU-specific form
    of output, where x specifies the CPU identification.

    For multiprocessor systems, /NOCPU produces a single modes screen
    that reflects the combined time that all CPUs spent in each mode.

    For nonmultiprocessor systems, the /CPU qualifier displays the
    CPU ID; /NOCPU does not display the CPU ID.
