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

    QUANTUM defines the following:

    o  Processor time: maximum amount of processor time a process
       can receive before control passes to another process of equal
       priority that is ready to compute

    o  Balance set residency: minimum amount of service a compute-
       state process must receive before being swapped out to
       secondary storage

    QUANTUM has the DYNAMIC and MAJOR attributes. On Alpha systems,
    QUANTUM also has the AUTOGEN attribute.
