The application discloses an inter-node communication method and an electronic device, relates to the technical field of inter-node communication, and comprises the following steps: when a first node is initialized, a first completion queue group and a first queue pair group are created to form a first resource pool, and a first memory pool is applied as a unified storage area; when the first node joins a cluster, a node announcement message is sent to other nodes in the cluster; in response to the first node receiving a communication task pointing to a second node, a first queue pair is selected from available queue pairs, and a first memory area is divided from the first memory pool; the second queue pair number and the second remote access key of the second node are obtained from a preset connection table; and based on the first queue pair and the first memory area, a remote memory direct access operation is initiated to access the opposite end identified by the second queue pair number with the second remote access key, thereby solving the technical problem of long inter-node communication delay in the prior art, and improving the efficiency and reliability of inter-node communication.

This invention discloses a method and system for exchanging local and remote memory objects in a single-copy mode. First, the invention constructs a logical address space and deploys it on memory nodes, establishing a unified correspondence between spatial addresses and virtual memory addresses. A memory management unit then translates virtual memory addresses into physical addresses. Second, a unique-copy mode is used to trigger object swapping operations, and an asynchronous garbage collection mechanism balances memory release efficiency with operational stability. Finally, a dedicated memory allocator improves memory management efficiency, including a split memory layout, a kernel offloading mechanism, and multi-partition load balancing. This invention avoids inter-process address switching overhead through a unified address space; eliminates data redundancy and multi-copy synchronization overhead through a unique-copy mode; and improves memory allocation efficiency through a split memory layout, kernel offloading, and multi-partition management mechanisms, achieving efficient utilization of remote memory resources and high-performance scheduling in multi-process shared scenarios.
