Method, device and system for migrating resources

摘要

Disclosed are a method and device for migrating resources, relating to the field of processors, avoiding memory access across nodes and cache access across nodes, saving inter-node high-speed bandwidth, and improving the system performance. The present invention includes: when a node is removed, obtaining a process in the node; determining the destination node to which the process and the corresponding memory thereof will be migrated according to the mapping relation between the process and the corresponding memory thereof and the affinity of the process; and migrating the process in the node and the corresponding memory thereof to the destination node. The embodiments of the present invention are mainly used in the resource migration process.
