cluster-name

    The name you want assigned to the cluster.

 base-address

    The base virtual address for the cluster. If you omit the base-
    address value, you must still enter the comma.

    On I64 systems, the base address must be omitted.

    For Alpha linking, it is illegal to specify a base address for a
    cluster when creating a shareable image.

 pfc (page fault cluster)

    The number of pagelets read into memory by the operating system
    when the initial page fault occurs for a page in the cluster. If
    you do not specify the pfc parameter, the operating system uses
    the default value established by the system parameter PFCDEFAULT.
    If you omit the page fault cluster value, you must still enter
    the comma.

 file-spec

    The file you want the linker to place in the cluster. Note that
    you should not specify in the LINK command itself any file that
    you specify with the CLUSTER= option (unless you want to include
    two copies of the file in the final image).
