Abstract: A computer system includes a first computing node and a second computing node. The first computing node includes a first device and a first memory. The second computing node includes a second device and a second memory. The first memory includes a first memory space. The second memory includes a second memory space. The first device obtains a cross-node read instruction. The cross-node read instruction includes a virtual address of the second memory space and a size of first data. The first device determines an identifier (ID) of the second computing node based on the virtual address of the second memory space and a first correspondence, to obtain a first network transmission packet, and sends the packet to the second device. The second device receives the packet, reads the first data from the second memory space, and sends the first data to the first device.
