Memory management method, memory management apparatus and NUMA system

A memory management apparatus, comprising:

• a first receiving module, configured to receive a memory allocation request message sent by a processor, wherein the memory allocation request message comprises memory demand information, and send the memory allocation request message to a node management module;
• the node management module, configured to receive the memory allocation request message sent by the first receiving module, and determine, according to the memory demand information in the memory allocation request message and memory attribute information of a local node of the processor, whether a memory unit corresponding to the local node meets the memory demand information;
• a memory controller management module, configured to, when the memory unit corresponding to the local node of the processor meets the memory demand information, determine a memory controller meeting the memory demand information and in the local node according to the memory demand information and first management information corresponding to the local node, wherein the first management information comprises an identifier of a memory controller in the local node and memory attribute information of the memory controller, and send the identifier of the memory controller meeting the memory demand information to a memory management area management module;
• the memory management area management module, configured to receive the identifier of the memory controller meeting the memory demand information and sent by the memory controller management module, determine at least one piece of second management information corresponding to the memory controller according to the identifier of the memory controller, determine a memory management area meeting the memory demand information and in the memory controller according to the memory demand information and the at least one piece of second management information, wherein the second management information comprises an identifier of a memory unit corresponding to the memory controller and attribute information of the memory unit, and send an identifier of the memory management area meeting the memory demand information to a memory allocation module;
• and
• the memory allocation module, configured to receive the identifier of the memory management area meeting the memory demand information and sent by the memory management area management module, and allocate memory space corresponding to the memory management area to the processor according to the identifier of the memory management area.

A non-transitory computer-readable medium having computer usable instructions stored thereon for execution by a processor, wherein the instructions cause the processor to:

• receive a memory allocation request message sent by a processor, wherein the memory allocation request message comprises memory demand information;
• determine, according to the memory demand information and memory attribute information of a local node of the processor, whether a memory unit corresponding to the local node meets the memory demand information;
• determine, when the memory unit corresponding to the local node of the processor meets the memory demand information, a memory controller meeting the memory demand information and in the local node according to the memory demand information and first management information corresponding to the local node, wherein the first management information comprises an identifier of a memory controller in the local node and memory attribute information of the memory controller;
• determine at least one piece of second management information corresponding to the memory controller according to the identifier of the memory controller meeting the memory demand information, and determining a memory management area meeting the memory demand information and in the memory controller according to the memory demand information and the at least one piece of second management information, wherein the second management information comprises an identifier of a memory unit corresponding to the memory controller and attribute information of the memory unit;
• and
• allocate memory space corresponding to the memory management area to the processor according to an identifier of the memory management area meeting the memory demand information.
