Abstract: A memory management method implemented by a requesting node includes sending first indication information used for indicating a length of memory required by the requesting node and receiving second indication information used for indicating first remote memory provided to the requesting node by a target contributing node in at least one contributing node that can provide remote memory. The method also includes determining, from available virtual addresses, a first virtual address corresponding to the first remote memory, and sending a first data read/write instruction for the first data when first data whose pointer is within a range of the first virtual address needs to be read/written, where the first data read/write instruction includes third indication information, and the third indication information is used for indicating storage space, for storing the first data, in the first remote memory.

Abstract: A cross-page prefetching method, apparatus, and system are disclosed, which can improve a prefetching hit ratio of a prefetching device, and further improve efficiency of memory access. The method includes: receiving an indication message, sent by a cache, that a physical address is missing, where the indication message carries a mapped-to first physical address and contiguity information of a first physical page to which the first physical address belongs; acquiring a prefetching address according to the first physical address and a step size that is stored in a prefetching device; and if a page number of a physical page to which the prefetching address belongs is different from a page number of the first physical page, and it is determined, according to the contiguity information of the first physical page, that the first physical page is contiguous, prefetching data at the prefetching address.
