Memory Access Method and Apparatus, Storage Medium, and Computer Program Product

A computing system, comprising:

• a first computing node comprising:
• a first processor;
• a first core in the first processor and configured to send a first memory access request, wherein the first memory access request carries a first virtual address (VA);
• and
• a first memory management unit (MMU) in the first processor and configured to:
• receive the first memory access request;
• query a first memory page table based on the first VA, to obtain a first query result, wherein the first query result comprises first routing information and a first physical address (PA);
• and
• send a second memory access request to a target module indicated by the first routing information,
• wherein the second memory access request carries the first PA, and
• wherein the second memory access request instructs the target module to obtain memory data based on the first PA and return the memory data to the first core.

A computer program product comprising computer-executable instructions that are stored on a non-transitory computer-readable medium and that when executed by at least one processor, cause a computing node to:

• receive, by a first memory management unit (MMU), a first memory access request from a first core, wherein the first memory access request carries a first virtual address (VA);
• query, by the first MMU, a first memory page table based on the first VA, to obtain a first query result, wherein the first query result comprises first routing information and a first physical address (PA);
• and
• send, by the first MMU, a second memory access request to a target module indicated by the first routing information,
• wherein the second memory access request carries the first PA, and
• wherein the second memory access request instructs the target module to obtain memory data based on the first PA and to return the memory data to the first core.
