Memory management method, memory management device and numa system

Abstract

Embodiments of the present invention provide a memory management method, a memory management device, and a NUMA system. The memory management method includes: receiving a memory allocation request message sent by a processor, where the memory allocation request message includes memory requirement information; determining the processor according to the memory requirement information Whether there is a memory controller that satisfies the memory requirement information in the local processing node; if it exists, determine the memory management area that meets the memory requirement information in the memory controller that meets the memory requirement information, and correspond to the memory management area that meets the memory requirement information of memory allocated to the processor. By determining the memory management area that meets the requirements in the memory controller that meets the requirements and assigning it to the processor that meets the requirements, there is no need to determine the memory controller and memory management area in the processing nodes that do not meet the requirements, and the storage area that meets the requirements can be quickly found. , improving memory allocation efficiency.

Description

technical field [0001] The embodiments of the present invention relate to computer technology, and in particular to a memory management method, a memory management device and a NUMA system. Background technique [0002] With the rapid development of computer technology, people's requirements for computer data processing capabilities are increasing. It is urgent to form a distributed system with multiple processors. Non Uniform Memory Access Architecture (NUMA for short) technology is a distributed system. [0003] The NUMA system connects several processing nodes through a high-speed dedicated network to form a multi-processor server system. Each processing node is composed of several CPUs or Symmetrical Multi-Processing (SMP) to improve data processing capabilities. In order to manage the memory of the NUMA system, the existing memory management technology simply divides the NUMA memory system into two layers: node and management area. The node controls and manages a set o...

Problems solved by technology

However, as the NUMA system grows larger, the number of processing nodes and memory size also increase accordingly, and the management area linked list to be maintained will be huge, and the process of finding a management area that meets the requirements may traverse the management area linked list. Resulting in less efficient memory allocation and management
