Abstract

PURPOSE:To ensure the highly effective application of a main storage device in case the pages have different using frequencies within a segment, by securing such constitution where a memory control means controls the main storage device based on the resident priority and the least recently used algorithm of each page of the segment. CONSTITUTION:A load module stored in a secondary storage device 1 of a virtual storage control system consists of plural segments. Each of these segments has the same constitution as a segment 2 consisting of a segment information describing area 3 and pages 4-7. At the same time, the information stored in the area 3 includes a load module name containing the segment 2. Then the segment 2 of a load module stored in the device 1 is loaded on a main storage device 8 via a memory control means 9. In this case, a load module recognizing means 10 refers to the area 3 to obtain the load module name and then refers to a list of load modules of a control information recording means 11 based on the load module name.
