<p>A memory management method and apparatus for multi-step non-uniform memory access NUMA architectures, the method comprises: when a system is initialized, determines the node group according to the delay information of the memory access of each node and user configuration information; obtains the memory use condition of each group and nodes in the node group, the memory use condition includes memory use ratios and free state indications; when a system initiates node memory configuration request, selects the free node group having the minimum memory access delay to distribute the memory according to the memory use conditions of each node group; and in the selected node group, distributes the memory to the node of the node group according to the memory use condition of the nodes in the node group. By the method, the characteristic of the multi-step non-uniform memory access architecture can be utilized, thereby both covering the efficiency and bandwidth effectively, and improving the memory management performance of the system.</p> |
