Abstract : In multiple-access computer systems, emphasis is placed upon servicing several interactive users simultaneously. However, many computations do not require user interaction, and the user may therefore want to run these computations 'absentee' (or, user not present). A mechanism is presented which provides for the handling of absentee computations in a multiple-access computer system. The design is intended to be implementation-independent. Some novel features of the system's design are: a user can switch computations from interactive to absentee (and vice versa), the system can temporarily suspend and then continue absentee computations to aid in maintaining an efficient absentee-interactive workload on the system, system administrative personnel can apportion system resources between interactive and absentee computations in order to place emphasis upon a particular mode during certain periods of operation, and the system's multiple-computation-stream facility allows the user to attach priorities to his absentee computations by placing the computations in either low-, standard-, or high-priority streams.
