  • Patent number: 6996828
    Abstract: A physical memory of a single computer is divided for each of a plurality of operating system (OS). A first OS is first loaded into the computer and runs. A multi-OS management program common to a plurality of OSs is incorporated into a virtual address space of the first OS as a device driver of the first OS. The multi-OS management program incorporated as the device driver is rearranged in a memory area shared by OSs so that the multi-OS management program has the same virtual address in any OS. In this state, the second OS program itself is loaded in the virtual address space of the second OS by execution of the multi-OS management program in the first OS. Execution of the multi-OS management program is switched from the multi-of management program in the first OS to the multi-OS management program in the second OS. Then, the second OS is started by execution of the multi-OS management program in the second OS to thereby run the plurality of OSs on the single computer.

  • Publication number: 20050262508
    Abstract: In a cluster system including a plurality of operating systems operating on one computer, computer resources can be updated for and reallocated to each operating system. When the operating systems are used as active or standby operating systems, a multiple operating system management controller monitors the state of each operating system. At a failure of an active operating system, the controller allocates a larger part of computer resources to another operating system in a normal state and assigns the operating system as a new active operating system. Regardless of the failure, the computer system can be operated without changing processing capability thereof. The controller can monitor load of each operating system to allocate computer resources to the operating system according to the load.

  • Publication number: 20050187698
    Abstract: An apparatus for controlling the distance between vehicles enables the distance to be controlled smoothly. A target vehicle speed determining section sets target vehicle speed based on the distance deviation between actual inter-vehicular distance and target inter-vehicular distance between host vehicle and preceding vehicle, and on the traveling speed of the preceding vehicle; calculates a temporary target vehicle speed based on traveling speed of the preceding vehicle and on the distance deviation; calculates a predicted arrival time for the host vehicle to reach the preceding vehicle based on the actual inter-vehicular distance and on the relative speeds between the two vehicles; and calculates a target vehicle speed limit value based on this predicted arrival time and on the traveling speed of the host vehicle, and sets as the target vehicle speed a value obtained by limiting the temporary target vehicle speed using this target vehicle speed limit value.
