Allocation of memory ranks based on access traffic

A computing device, comprising:

• a memory comprising at least two rank groups, wherein the at least two rank groups being controlled by a single memory controller, wherein each rank group of the at least two rank groups comprises at least two ranks, wherein first portions of address information in addresses of ranks in one rank group of the at least two rank groups are the same, wherein a first mapping relationship exists between the first portion of address information and information about a first preset location in a physical address of a memory page in the memory, and wherein the first preset location is a portion of page number information in the physical address;
• and
• a processor coupled to the memory, the processor configured to:
• receive a memory access request, wherein the memory access request carries a to-be-accessed virtual address;
• select a target rank group from the at least two rank groups, according to access traffic of the at least two rank groups, and in response to determining that no memory page has been allocated to the virtual address;
• and
• select, from idle memory pages, a to-be-allocated memory page for the virtual address, wherein the information about the first preset location in a physical address of the memory page that is selected as the to-be allocation memory page is the same as the first portions of address information in addresses of ranks in the target rank group, and wherein storage units in the to-be-allocated memory page are distributed in ranks in the target rank group.

A non-transitory computer readable storage medium comprising one or more computer-executable instructions, wherein the one or more computer-executable instructions, when executed on a processor of a computer system, cause the processor to:

• receive a memory access request requesting access to a memory of the computer system, wherein the memory access request carries a to-be-accessed virtual address;
• select a target rank group from at least two rank groups in the memory according to access traffic of the at least two rank groups in response to determining that no memory page has been allocated to the virtual address, wherein the at least two rank groups being controlled by a single memory controller, wherein each rank group of the at least two rank groups comprises at least two ranks, wherein first portions of address information in addresses of ranks in one rank group of the at least two rank groups are the same, wherein a first mapping relationship exists between the first portion of address information and information about a first preset location in a physical address of a memory page in the memory, and wherein the first preset location is a portion of page number information in the physical address;
• and
• select, from idle memory pages, a to-be-allocated memory page for the virtual address, wherein the information about the first preset location in a physical address of the memory page that is selected as the to-be allocation memory page is the same as the first portions of address information in addresses of ranks in the target rank group, and wherein storage units in the to-be-allocated memory page are distributed in ranks in the target rank group.
