Memory page management method, system, and apparatus, device, and computer non-volatile readable storage medium

A memory page management system, comprising at least two racks, each rack comprising at least two target nodes, each target node comprising a target processor and a memory, the target processor of the target node being connected with the memory of at least one other target node located on the same rack and the memory of at least one target node located on different racks,

• wherein the target processor is configured to acquire a target virtual address of data to be accessed;
• perform a physical address lookup in a translation lookaside buffer based on the target virtual address, the translation lookaside buffer storing mapping relationships between target physical addresses in a local memory and other memories and corresponding virtual addresses, wherein the target physical addresses comprise physical addresses of first popularity data, and popularity data comprises data satisfying hot access conditions;
• read target data to be accessed from a physical address to be accessed in a case that the physical address to be accessed, corresponding to the target virtual address, is found in the translation lookaside buffer;
• and
• perform a parallel physical address lookup in a local memory page table and other memory page tables based on the target virtual address in a case that the physical address to be accessed is not found in the translation lookaside buffer, and read the target data to be accessed from the physical address to be assessed in a case that the physical address to be accessed is found, the local memory page table comprising page tables that store mapping relationships between physical addresses in the local memory and corresponding virtual addresses, the other memory page tables comprising page tables that store mapping relationships between physical addresses in the other memories and corresponding virtual addresses, and the local memory comprising a memory connected with the target processor in the target node, while the other memories comprising memories connected with the target processor in other nodes except the target node.

An electronic device, comprising:

• a memory, configured to store a computer program;
• and
• a processor, configured to implement, when executing the computer program, the computer program instructions implement to:
• acquire a target virtual address of data to be accessed;
• perform a physical address lookup in a translation lookaside buffer based on the target virtual address, the translation lookaside buffer storing mapping relationships between target physical addresses in a local memory and other memories and corresponding virtual addresses, wherein the target physical addresses comprise physical addresses of first popularity data, and popularity data comprises data satisfying hot access conditions;
• read target data to be accessed from a physical address to be accessed in a case that the physical address to be accessed, corresponding to the target virtual address, is found in the translation lookaside buffer;
• and
• perform a parallel physical address lookup in a local memory page table and other memory page tables based on the target virtual address in a case that the physical address to be accessed is not found in the translation lookaside buffer, and reading the target data to be accessed from the physical address to be assessed in a case that the physical address to be accessed is found,
• wherein the local memory page table comprises page tables that store mapping relationships between physical addresses in the local memory and corresponding virtual addresses;
• the other memory page tables comprise page tables that store mapping relationships between physical addresses in the other memories and corresponding virtual addresses;
• and the local memory comprises a memory connected with the target processor in the target node, while the other memories comprise memories connected with the target processor in other nodes except the target node.
