Abstract
A multiprocessor system according to an embodiment comprises a plurality of processors, an execution control unit to control processing by the plurality of processors and data transfer between the plurality of processors; and an internal data storage unit to store data dependence information indicating status of the data transfer. If control flow of processing by a processor is fixed after a preceding data transfer is registered for execution and another data transfer to a similar destination as the preceding data transfer is necessary, the execution control unit cancels the preceding data transfer based on the data dependence information.
