TASK PLACEMENT DEVICE, TASK PLACEMENT METHOD AND COMPUTER PROGRAM

摘要

The task placement device includes: a task set parameter acquisition section which acquires task set parameters including information indicating the dependence relationship among tasks contained in a task set, and a required execution time needed for execution of each task; a first task placement section configured to, for a task which is capable of being executed within a scheduling-anticipated period, determine core allocation, taking into consideration scheduling based on the task set parameters; and a second task placement section configured to, for a task except first task placed by the first task placement section, determine the core allocation based on the task set parameters.

主权项

1. A task placement device comprising:
a task set parameter acquisition section configured to, for a task set which is dynamically controlled while being executed with respect to scheduling of tasks on at least a processor core, acquire task-set parameters including at least a subset of pieces of information representing dependency relations among the tasks and a subset of required execution periods each required to complete execution of a corresponding one of the tasks; a first task placement section configured to, with respect to each of at least a first task which is among the tasks included in the task set and which becomes ready for execution within the scheduling foreseeable period, perform task placement processing by determining a core allocation in view of scheduling based on the task-set parameters; and a second task placement section configured to, with respect to a task except the first task performed by the first task placement section, perform task placement processing by determining a core allocation based on the task-set parameters.
