Suspension of Processes in a Multiprocessing Computer System

摘要

The document defines the notion of a suspension capability and sets down the requirements such a capability makes on a computing system. A simple model of a computing system enables a more detailed statement of those requirements. A cursory investigation of the Multics computing system shows why it is difficult to implement a suspension capability in multiprocessing systems with direct sharing, and, in particular, in Multics.
