/RAD=n

    Specifies the RAD number on which the submitted batch job is to
    execute.

    When a job is submitted to a batch queue that does not have a
    RAD setting, the job will execute using the RAD specified. If the
    batch queue has a RAD setting, the job will execute using the RAD
    specified on the queue.

    RAD is supported on AlphaServer GS series systems and starting
    from OpenVMS Version 8.4, support is extended to NUMA capable
    Integrity servers.
