Allocating task groups to processor cores based on number of task allocated per core, tolerable execution time, distance between cores, core coordinates, performance and disposition pattern

Abstract

Even if a multiprocessor includes an uneven performance core, an inoperative core or a core that does not satisfy such a performance as designed but if the contrivance of task allocation can satisfy the requirement of an application to be executed, the multiple processors are shipped. In a task group allocation method for allocating, to a processor having a plurality of cores, task groups included in an application for the processor to execute, a calculation section measures performances and disposition patterns of the cores, generates a restricting condition associating the measured performances and disposition patterns of the cores with information indicating whether the application can be executed, and, with reference to the restricting condition, reallocates to the cores, the task groups that have previously been allocated to the cores.
