    • A computer system has a plurality of computer nodes, and each computer node has a plurality of virtual computers and a control base unit controlling the virtual computers. Each virtual computer constitutes a multiplexing group with another virtual computer operating on another computer node different from its own computer node, with one operating as the master and the other as the slave. The control base unit controls whether each virtual computer is operating as either the master or the slave, and monitors the respective states of each virtual computer. The control base unit, when it has detected in its own node a failure of the virtual computer operating as the master virtual computer, makes a decision whether to also switch the other virtual computers operating on its own computer node from master virtual computers to slave virtual computers with the virtual computer in which the failure occurred.
    • 计算机系统具有多个计算机节点,并且每个计算机节点具有多个虚拟计算机和控制虚拟计算机的控制基础单元。 每个虚拟计算机构成与另一计算机节点操作的另一个虚拟计算机的复用组,该计算机节点与其自己的计算机节点不同,其中一个作为主机操作,另一个作为从机。 控制基本单元控制每个虚拟计算机是作为主机还是从机操作,并监视每个虚拟计算机的各自的状态。 控制基站单元在其自身节点中检测到虚拟计算机作为主虚拟计算机操作的故障时,决定是否将其自己的计算机节点上运行的其他虚拟计算机从主虚拟计算机切换到从属虚拟计算机 具有发生故障的虚拟计算机的计算机。

    • A computer system includes a plurality of computer nodes, each including an external communications unit. An application unit executes processing in accordance with a processing request. A synchronization unit establishes synchronization of the processing between each computer node and other computer nodes. The processing is executed by each computer node, and an inter-node communications unit executes transmission/reception of information between each computer node and the other computer nodes. The synchronization unit transmits the processing request to the other computer nodes via the inter-node communications unit, the processing request being received by the external communications unit. Also, the synchronization unit receives processing requests from the other computer nodes as well via the inter-node communications unit. Based on the number of the computer nodes that have received the same processing request via the external communications units, the synchronization unit selects a processing request that should be executed by the application unit.
    • 计算机系统包括多个计算机节点,每个计算机节点包括外部通信单元。 应用单元根据处理请求执行处理。 同步单元建立每个计算机节点与其他计算机节点之间的处理的同步。 处理由每个计算机节点执行,并且节点间通信单元执行每个计算机节点与其他计算机节点之间的信息的发送/接收。 同步单元经由节点间通信单元向其他计算机节点发送处理请求,处理请求由外部通信单元接收。 此外,同步单元也经由节点间通信单元接收来自其他计算机节点的处理请求。 基于经由外部通信单元接收到相同处理请求的计算机节点的数量,同步单元选择应由应用单元执行的处理请求。
