Abstract: Embodiments of the present invention disclose a method and an apparatus for resource migration, related to the field of processors, to avoid cross-node memory access and cross-node cache access, save inter-node high-speed bandwidth, and improve system performance. The method of the present invention includes: when a node is removed, obtaining a process in the node; determining a destination node to which the process and the memory corresponding to the process are migrated, according to mapping between the process and the memory corresponding to the process, and affinity of the process; and migrate the process in the node and the memory corresponding to the process to the destination node. The embodiments of the present invention are mainly applied to a resource migration procedure.
