PROBLEM TO BE SOLVED: To provide an arithmetic processing system and a program which can reduce power consumption when a plurality of pieces of processing means use a plurality of recording media, compared to a system without the invented configuration.SOLUTION: A RAM manager 41 allocates storage areas of DRAM 51 to 53 to guest OS 1 to 3. When the total maximum use amounts of RAM by the guest OS 1 to 3 is less than the total amounts of memory of the DRAM 51 to 53 by an amount equal to or more than a memory amount of at least one piece of DRAM, storage areas which can secure the maximum use amounts of RAM by the respective guest OS 1 to 3 are re-allocated to the respective guest OS 1 to 3 in order to continuously arrange the storage areas on the DRAM 51 to 53. Then, when the re-allocation is performed, a refresh operation on an unused DRAM is stopped. |
