Memory allocation device, memory allocation method, and memory allocation program

摘要

PROBLEM TO BE SOLVED: To provide a memory arrangement device for suppressing a decrease in memory access performance of a process. SOLUTION: A memory allocation device 20 of a computer system in which a plurality of nodes that are a pair of a processor and a memory exist is a memory position determination unit 21 that determines a node in which a memory area to be mapped is arranged, and a determination result. Based on this, a mapping unit 22 that duplicates the memory area and arranges it in the local memory of the node on which the process operates is provided. The mapping unit disables maintaining cache coherency between nodes and disables access to remote memory for processes. [Selection diagram] FIG. 8
