    摘要： A spark ignition internal combustion engine includes a sub-combustion chamber in which gas mixture with an air-fuel ratio adapted for an operating state of the engine over a wide operating range of the engine is supplied to a combustion chamber. The amount of hydrogen carbide discharged is less and a high efficiency can be attained. The sub-combustion chamber of the internal combustion engine communicates with the main combustion chamber. Gas mixture injecting apparatus intermittently injects gas mixture into the sub-combustion chamber. Ignition devices are arranged in the sub-combustion chamber. The engine is constructed such that the sub-combustion chamber is eccentric in a sideward direction from an extending line of injecting direction of the gas mixture injecting apparatus and communicated with the main combustion chamber. The gas mixture injecting apparatus includes a pressure accumulating chamber adjacent to the sub-combustion chamber and to which pressure air is filled, the opening or closing valve to cause the pressure accumulating chamber to be communicated with the sub-combustion chamber in such a way that they may be opened or closed, and the fuel injecting valve for injecting fuel to the pressure accumulating chamber.

    摘要： Provided is a failover method for a cluster system for realizing smooth failover of the guest OS's, even when there are many guest OS's, while reducing consumption of computer resources of a server. Smooth failover is realized by preventing competition during failover even when the number of guest OS's is increased. In a cluster configuration in which a slave/master cluster program is operated in a guest OS/host OS, the master cluster program (510) collects and transmits heartbeats of the slave cluster program, thereby realizing failure monitoring through the certain amount of heartbeats without depending on the number of guest OS's. Further, when the master cluster program monitors failures of the slave cluster program of its own computer to find a normal operation of the guest OS, the amount of communication through heartbeats is reduced by eliminating the necessity of communication to a standby system slave cluster program.

    摘要： Even when a large number of guest OSs exist, a failover method meeting high availability needed by the guest OSs is provided for the each guest OS. In the event of a physical or logical change of a system, or change of operation states, a smooth failover method can be realized by preventing the consumption of resource amounts due to excessive failover methods, and the occurrence of systemdown due to an inadequate failover method. In a server virtualization environment, in a cluster configuration having a failover method due to hot standby and cold standby, by selecting a failover method meeting high availability requirements specifying performance during failover of applications on the guest OSs, a suitable cluster configuration is realized. Failure monitoring is realized by quantitative heartbeat.

    摘要： A method is provided which eliminates redundancy from the shadow PT operation performed by the virtual machine monitor (VMM) when the guest operating system running on a virtual machine updates a guest page table (PT) address. The VMM associates a plurality of shadow PTs with guest PTs and allocates their relation in memory. When it detects the update of a guest PT address, the VMM searches for a shadow PT corresponding to the updated guest PT. If the associated shadow PT exists, the VMM omits rewriting the shadow PT and registers the address of the shadow PT with the central processing unit (CPU). If the associated shadow PT does not exist, the VMM allocates a memory, creates a shadow PT, registers an address of the created shadow PT with the CPU, and records a relationship between the updated guest PT and the generated shadow PT.

    摘要翻译： 当在虚拟机上运行的客户操作系统更新访客页表（PT）地址时，提供一种消除虚拟机监视器（VMM）执行的阴影PT操作的冗余的方法。 VMM将多个阴影PT与客户PT相关联，并将其关系分配给内存。 当检测到客户PT地址的更新时，VMM搜索与更新的客户PT相对应的影子PT。 如果相关联的阴影PT存在，则VMM将省略重写阴影PT，并将阴影PT的地址与中央处理单元（CPU）注册。 如果相关联的阴影PT不存在，则VMM分配存储器，创建阴影PT，向CPU注册创建的阴影PT的地址，并记录更新的客户PT与生成的阴影PT之间的关系。
