Management method and management apparatus for hybrid memory system, device, and medium

A computer device, comprising a memory, a processor, and computer programs, the computer programs being stored in the memory and executable on the processor, and the processor, when executing the computer programs, implement steps of a management method for a hybrid memory system comprising:

• acquiring a write hotness value and an access hotness value of a currently accessed memory page;
• comparing the write hotness value with a specified write hotness threshold, and generating write hotness page migration flag information;
• comparing the access hotness value with a specified access hotness threshold, and generating access hotness page migration flag information;
• grouping a hybrid memory in the hybrid memory system, and generating memory page management information corresponding to the hybrid memory based on memory page information of all grouped memory banks;
• and
• determining whether the currently accessed memory page is a hot data page based on the write hotness page migration flag information, the access hotness page migration flag information, and current memory page management information corresponding to the currently accessed memory page, and performing data migration based on a preset cold and hot data page migration strategy;
• wherein the grouping a hybrid memory in the hybrid memory system, and generating memory page management information corresponding to the hybrid memory based on memory page information of all grouped memory banks comprises:
• dividing the hybrid memory in the hybrid memory system into a plurality of grouped memory banks based on a preset unified memory group capacity and a preset unified memory group memory ratio, and marshaling all the grouped memory banks;
• generating the memory page management information corresponding to the hybrid memory based on the memory page information of all the grouped memory banks;
• and
• acquiring programs in the system and specified grouped memory banks corresponding to the programs, and generating a memory group mapping relationship based on program calibration information of memory programs and grouped memory bank numbers of specified grouped memory banks corresponding to the memory programs.

A non-transitory computer-readable storage media storing computer programs, the computer programs, when executed by a processor, enable the processor to perform steps of management method for a hybrid memory system, comprising:

• acquiring a write hotness value and an access hotness value of a currently accessed memory page;
• comparing the write hotness value with a specified write hotness threshold, and generating write hotness page migration flag information;
• comparing the access hotness value with a specified access hotness threshold, and generating access hotness page migration flag information;
• grouping a hybrid memory in the hybrid memory system, and generating memory page management information corresponding to the hybrid memory based on memory page information of all grouped memory banks;
• and determining whether the currently accessed memory page is a hot data page based on the write hotness page migration flag information, the access hotness page migration flag information, and current memory page management information corresponding to the currently accessed memory page, and performing data migration based on a preset cold and hot data page migration strategy;
• wherein the grouping a hybrid memory in the hybrid memory system, and generating memory page management information corresponding to the hybrid memory based on memory page information of all grouped memory banks comprises:
• dividing the hybrid memory in the hybrid memory system into a plurality of grouped memory banks based on a preset unified memory group capacity and a preset unified memory group memory ratio, and marshaling all the grouped memory banks;
• generating the memory page management information corresponding to the hybrid memory based on the memory page information of all the grouped memory banks;
• and acquiring programs in the system and specified grouped memory banks corresponding to the programs, and generating a memory group mapping relationship based on program calibration information of memory programs and grouped memory bank numbers of specified grouped memory banks corresponding to the memory programs.
