A method and a device for balancing load of a multiprocessor system relate the resource allocation field of the multiprocessor system, for achieving the purpose of reducing the number of accessing a remote node memory or the amount of copying data when the processes migrated to a target Central Processing Unit (CPU) are performed. The method for balancing load of the multiprocessor system comprises: determining the local CPU and the target CPU in the multiprocessor system; sequencing the priorities of migration, based on the size of memory space occupied by the processes in the queue of the local CPU; wherein the less the memory space occupied by the process is, the higher the migration priority of the process is; and migrating the process whose migration priority is the highest other than the processes being performed in the queue of the local CPU into the target CPU. The solution provided by the present invention can be applicable to the multiprocessor system of Non-Uniform Memory Access (NUMA) Architecture. |
