However, many computations do not require interaction with the user, 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; the specifications for each module in the mechanism are presented in terms of the primitive functions which comprise the module. Perhaps the most novel features of the design are the ability for a user to switch one of his computations from interactive to absentee (and vice versa), the ability for the system to temporarily suspend and then continue absentee computations to aid in maintaining an efficient absentee-interactive workload on the system, the ability for system administrative personnel to apportion system resources between interactive and absentee computations in order to place emphasis upon a particular mode during certain periods of operation, and the multiple-computation-stream facility of the system which allows the user to attach priorities to his absentee computations by placing the computations in either low-, standard-, or high-priority streams.''('Abstract').
