  • Publication number: 20070124522
    Abstract: In a multi-node system, a node can be dynamically detached (e.g., responsive to an error situation) without impacting the operating system or others of the nodes. Contents of in-use memory at the node to be detached are copied to another node, and a memory map is updated to make the copy transparent to components using the memory. Furthermore, the copied-to memory locations are programmatically blocked to prevent assignment thereof to a memory requester.

  • Patent number: 7182047
    Abstract: A cooling system for an internal combustion engine mounted within a vehicle includes a radiator for rejecting heat to ambient air and an axial fan mounted within a fan shroud associated with a radiator. The fan has a stationary hub equipped with louvers which may be controlled so as to either block off or allow airflow through the hub, and consequentially through the radiator. In this manner, the airflow past the fan may be greatly increased when the vehicle is operated at a higher groundspeed, while decreasing the amount of power consumed by the fan.

  • Publication number: 20060086816
    Abstract: A method of conserving energy during a heating event wherein a coolant is heated in a cooling system is disclosed. The method includes establishing a first set point temperature for a first point in the cooling system and establishing a second set point temperature lower than the first set point temperature for a second point in the cooling system. Normally, the coolant is maintained at the second set point temperature at the second set point in the cooling system. During the heating event, the second set point temperature is raised to substantially match the first set point temperature to reduce necessary heating of the coolant at the first point.

  • Publication number: 20060047858
    Abstract: A method and system for booting up multiple PCI peripheral devices, such that the number of bootable PCI peripheral devices is not limited by the amount of computer system memory that is dedicated to storing executable boot code for the peripheral devices. The executable boot code is stored on a Read Only Memory (ROM) on each peripheral device. When a new PCI peripheral device begins to boot up, a check for available memory space in a ROM scan memory address space is performed. If there is not enough available room in the ROM scan memory address space for the new device's executable boot code, then a ROM scan detection logic pages an image of another peripheral device's executable boot code out of the ROM scan memory address space before storing the new device's executable boot code into the ROM scan memory address space.

  • Publication number: 20060010344
    Abstract: A system, method, and computer program product for reporting and recovering from an internal processor error in a multiprocessor system supporting system management mode. In accordance with the method of the present invention one or more replacement agents are allocated such as during system startup within the multiprocessor system. Machine specific error-reporting registers are monitored for one or more active processor agents during system operation. In response to detecting a faulty agent via the monitoring, a system management interrupt (SMI) request is issued to one or both the faulty agent and a selected replacement agent. In response to receiving the SMI request, the operating state of the faulty agent is copied to the selected replacement agent in system management mode. Operating system processing is then resumed using the replacement agent.

  • Publication number: 20050289362
    Abstract: A method of managing resources in a data processing configuration includes allocating system resources to an application to ensure a specified level of performance for the application. A system parameter is then modified to conserve power consumption upon detecting a condition resulting in a reduction of available system power. The original system resource allocation is then modified to maintain the specified level of performance following the modification of the system parameter. The system resources may include system CPU cycles and allocating system resources may include allocating a specified percentage of the CPU cycles to a high priority application. The reduction of available system power may be caused by an excessive ambient temperature or the failure of a power supply. Modifying the system parameter to conserve power consumption includes throttling the CPU speed and then dynamically increasing the percentage of CPU cycles allocated to the high priority application.

  • Publication number: 20050283523
    Abstract: A method and system for allowing nodes in a multi-node computer to be appropriated by a master node in the multi-node computer. The node to be appropriated is suspended into an ACPI S3 Sleep State, causing current system operations state information to be stored in a backup memory in the appropriated node. The master node then populated a primary memory in the appropriated node with OS and other information required to join a partition that includes the master node. When the master node no longer wishes to use the appropriated node, the backup memory in the appropriated node is mirrored back into the primary memory. When the appropriated node “wakes up” from the S3 state, it continues executing software commands where it left off, without knowing anything that had happened after going into the S3 state.

  • Publication number: 20050274814
    Abstract: A selectable coolant heating system for a fuel cell electric vehicle is disclosed. The selectable coolant heating system includes a maximum heat button which is connected to a coolant heater that heats a vehicle coolant when the maximum heat button is depressed. The coolant heater is maintained in either a de-activated, non-heating “off” mode or a baseline heating mode unless and until it is activated by depression of the maximum heat button, at which time the heater is activated to a heating level mode or to one of multiple, successively-higher heating level modes, respectively. By subsequent depression of the maximum heat button, the non-heating “off” mode of the coolant heater can be resumed in order to conserve energy and improve vehicle fuel economy.

  • Patent number: 6904762
    Abstract: A novel pump pressure limiting method for preventing coolant in a cooling system from reaching pressures that exceed predetermined system coolant pressure limits. The method includes reducing the system coolant pressure, as needed to prevent system over-pressurization, by reducing the operational speed of a coolant pump used to pump the coolant through the system. In one embodiment, the system coolant pressure is determined directly, by measurement of the pressure of the coolant in the system typically using pressure sensors. The operational speed of the coolant pump is then reduced until the system coolant pressure decreases to within the predetermined pressure limits. In another embodiment, the system pressure is determined indirectly, by obtaining pressure-indicating data such as coolant temperature. The coolant system pressure is then correlated with the coolant temperature or other data and then the operational speed of the coolant pump is reduced accordingly.

  • Publication number: 20050097208
    Abstract: A method and system for method of removing a node from a multi-node computer. The node receives a system management interrupt (SMI), resulting in a quiescenting of only that node. The SMI receiving node then polls other nodes in the multi-node computer to determine if the SMI affects an operation of any of the other nodes, and quiescents any other node affected by the SMI. Each quiescent node then transfers all of the contents of its system memory to a backup memory in an unaffected remote node in the multi-node computer. The remote node than assumes the function of the removed node that had received the SMI. The method and system thus allows node removal in the event of a hot-swap request or a predicted failure of a node.
