  • Patent number: 8959370
    Abstract: The invention concerns scheduling an application comprised of precedence constrained parallel tasks on a high-performance computer system. The computer system has a plurality of processors each enabled to operate on different voltage supply levels. First, a priority order for the tasks based on the computation and communication costs of the tasks is determined. Next, the based on the priority order of the tasks, assigning each task both a processor and a voltage level that substantially minimizes energy consumption and completion time for performing that task when compared to energy consumption and completion time for performing that task on different combinations of processor and voltage level. It is an advantage of the invention that the scheduling takes account not only completion time (makespan), but also energy consumption. Aspects of the invention include a method, software, a scheduling module of a computer and a schedule.

  • Patent number: 8886382
    Abstract: A method is described of regulating movement of an autonomous entity between a first zone (904) and a second zone (901), wherein the first and second zones each have an operation-defined geographical boundary within a defined geographical region. The autonomous entity is instructed to move into a transition zone (906, 907) that spans the first zone and the second zone, wherein the autonomous entity while located in the first zone is responsive to supervisory control of a first controller (912) associated with the first zone. The autonomous entity is registered with a second controller (910) associated with the second zone to enable the autonomous entity to respond to supervisory control of the second controller as the autonomous entity enters the second zone through the transition zone. The autonomous entity is de-registered from the first controller.
