MEMORY MANAGEMENT PROGRAM, MEMORY MANAGEMENT METHOD, INFORMATION PROCESSING DEVICE, AND COMPUTER-READABLE RECORDING MEDIUM UPON WHICH MEMORY MANAGEMENT PROGRAM HAS BEEN RECORDED

摘要

A computer, which includes a plurality of arithmetic processing units, a main memory that stores data, and a cache memory that is shared from the plurality of arithmetic processing units and holds a part of the data stored in the main memory, and allows a plurality of virtual computers to operate executes the following process. In other words, an instruction to arrange a program on a region of a virtual memory that is a virtualized memory of the virtual computer is given. Then, when the instruction to arrange the program on the region of the virtual memory is received, it is determined whether or not a program of an arrangement target remains arranged on the main memory. When it is determined that the program of the arrangement target remains arranged on the main memory, a region of the main memory on which the program of the arrangement target is arranged is associated with the region of the virtual memory. However, when it is determined that the program of the arrangement target does not remain arranged on the main memory, the program of the arrangement target is arranged on the region of the virtual memory.
