/sys$common/syshlp/SYSGEN.HLB  —  Sys Parameters, MULTIPROCESSING
    MULTIPROCESSING controls the loading of the system
    synchronization image.

    Specify one of the following values:

    Value    Description

    0        Load the uniprocessing synchronization image
             SYSTEM_SYNCHRONIZATION_UNI.EXE.

    1        If the CPU type is capable of SMP and two or
             more CPUs are present on the system, load the
             full-checking multiprocessing synchronization
             image SYSTEM_SYNCHRONIZATION.EXE. Otherwise,
             load the uniprocessing synchronization image
             SYSTEM_SYNCHRONIZATION_UNI.EXE.

    2        Always load the full-checking version
             SYSTEM_SYNCHRONIZATION.EXE, regardless of system
             configuration or CPU availability.

    3        If the CPU type is capable of SMP and two or more
             CPUs are present on the system, load the optimized
             streamlined multiprocessing image:

             o  On Alpha and Integrity servers, this image is
                SYSTEM_SYNCHRONIZATION_MIN.EXE.

             Otherwise, load the uniprocessing synchronization image
             SYSTEM_SYNCHRONIZATION_UNI.EXE. The default value is 3.

    4        Always load the streamlined multiprocessing image
             SYSTEM_SYNCHRONIZATION_MIN.EXE, regardless of system
             configuration or CPU availability.

    Setting the SYSTEM_CHECK parameter to 1 has the effect of setting
    MULTIPROCESSING to 2.
