MEMORY MANAGEMENT METHOD, MEMORY MANAGEMENT DEVICE AND NUMA SYSTEM

摘要

Provided are a memory management method, a memory management device and a NUMA system. The memory management method comprises: receiving a memory allocation request message sent by a processor, the memory allocation request message containing memory requirement information; according to the memory requirement information, determining whether a memory controller satisfying the memory requirement information exists in a local processing node of the processor; and if it exists, determining a memory management region satisfying the memory requirement information in the memory controller satisfying the memory requirement information, and allocating a memory corresponding to the memory management region satisfying the memory requirement information to the processor. By determining a memory management region satisfying requirements in a memory controller satisfying the requirements and allocating the memory to a processor with the requirements, there is no need to determine a memory controller and a memory management region in a processing node not satisfying the requirements, and a memory region satisfying the requirements can be rapidly found, thereby improving the memory allocation efficiency.
