Memory management method, memory management apparatus and NUMA system

摘要

Embodiments of the present invention provide a memory management method, a memory management apparatus and a NUMA system. The memory management method includes: determining, according to a memory demand information which includes memory demand information sent by a processor, whether a memory controller meeting the memory demand information exists in a local processing node which the processor; and if exists, determining, in the memory controller meeting the memory demand information, a memory management area meeting the memory demand information, and allocating the memory management area meeting the memory demand information to the processor. Therefore, the memory controller and the memory management area do not need to be determined in a processing node that does not meet the requirements, which can rapidly find a storing area meeting the requirements, and improve the memory allocation efficiency.

主权项

1. A memory management method, comprising:
receiving a memory allocation request message sent by a processor, wherein the memory allocation request message comprises memory demand information; determining, according to the memory demand information and memory attribute information of a local node of the processor, whether a first memory unit corresponding to the local node meets the memory demand information; determining, when the first memory unit does not meet the memory demand information, a node group meeting the memory demand information according to the memory demand information and third management information, wherein the third management information comprises an identifier of the node group and memory attribute information of the node group; and determining fourth management information corresponding to the node group according to the identifier of the node group meeting the memory demand information, and determining that a node which is comprised in the node group meets the memory demand information according to the memory demand information and the fourth management information, wherein the fourth management information comprises an identifier of the node in the node group and memory attribute information of the node.
