  • Patent number: 9940598
    Abstract: A first executing unit executes, among tasks included in a first workflow, a first task group including one or more tasks using a resource. When a task included in the first task group is stopped, a rollback processing unit restores the resource to its former state prior to the execution of the first task group. After the resource is restored to the former state prior to the execution of the first task group, a second executing unit starts executing, among tasks included in a second workflow, a second task group including one or more tasks using the resource.
