Abstract
A method and a device for balancing load of a multiprocessor system relate to the resource allocation field of the multiprocessor system, for achieving the object of reducing the number of accessing a remote node memory or the amount of copying data when the processes migrated into a target Central Processing Unit (CPU) are performed. The method for balancing the load of the multiprocessor system includes: determining the local CPU and the target CPU in the multiprocessor system; sequencing the migration priorities, based on the size of memory space occupied by the processes in the queue of the local CPU; where 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.
