IMPLEMENTING MULTI-PROCESS PRIMITIVES IN A MULTIPLEXED COMPUTER SYSTEM.

摘要

In any computer system,primitive functions are needed to control the actions of processes in the system. The thesis discusses a set of six such process-control primitives which are sufficient to solve many of the problems involved in parallel processing,as well as in the efficient multiplexing of system resources among the many processes in a system. In particular,the thesis documents the work performed in implementing these primitives in a particular computer system -the Multics system -which is being developed at M.I.T.'s Project MAC. During the course of work that went into the implementation of these primitives,design problems were encountered which caused the overall program design to go through two iterations before program performances was deemed acceptable. The thesis discusses the way the design of these programs evolved during the course of this work. (Author)
