摘要： Provided are a load balancing method and a load balancing apparatus in a symmetric multi-processor system. The load balancing method includes selecting at least two processors based on a load between a plurality of processors, from among the plurality of processors, migrating a predetermined task stored in a run queue of a first processor to a migration queue of a second processor, and migrating the predetermined task stored in the migration queue of the second processor to a run queue of the second processor. Accordingly, a run queue of a processor is not blocked while migrating a task, an immediate response of the run queue is possible, and a waiting time of a scheduler is reduced. Consequently, the scheduler can speedily perform context switching, and thus performance of the entire operating system is improved.

The method comprises setting a transfer unit in a data processing system which repeatedly performs a process of transmitting data stored in a first memory to a second memory in a predetermined transfer unit, processing the transmitted data stored in the second memory, and transmitting the processed data to the first memory. The method includes computing overhead on the data processing system according to the size of each of a plurality of data units available as the transfer unit; and setting a data unit, which corresponds to a minimum overhead from among the computed overheads, as the transfer unit. Accordingly, it is possible to set an optimum transfer unit according to an environment of a data processing system in order to improve the performance of the data processing system.
