  • Task allocation method and task allocation apparatus
    Patent number: 7930339
    Abstract: A distributed processing system includes plural nodes each provided with a processor and communicably connected to each other. A task information obtaining unit obtains antecedent dependency between tasks. A node information obtaining unit obtains a time constraint imposed on the tasks. A start time computing unit computes an absolute earliest start time at which a task can be started and an absolute latest start time allowed in order to complete the task within the time constraint, by referring to the time constraint. A node selector selects a destination node to which a target task not yet allocated to a node should be allocated, by referring to the absolute earliest start time and the absolute latest start time. A task placement unit causes the task to be executed in the selected node.
