Abstract

The paper is devoted to the organization and efficiency of virtual memory in a system with many processes. The use of virtual memory by many (quasi) parallel processes is shown to permit: constructing effective page replacement alro- rithms; reducing the average page transmission time by executing at each time that reference which requires the minimal time; reducing the number of repeated calls by rearranging the references. A set of commands for parallel processing organization is given. Software and hardware realizations of these commands are discussed. Specific examples illustrate improvement of the efficiency of virtual memory achieved by using many parallel processes.
