    • Parallel processors communicate with each other over a network by transmitting messages that include destination processor information. A message controller for each processor in the network receives the messages and checks for faults in the message, particularly in the destination processor number contained in a first word of the message. If a fault occurs in the destination processor number, then the faulty message is transmitted to an appropriate processor for handling the fault. In this way the network operation is not suspended because of the fault and the message is not left in the network as a result of the error occurring in the destination processor number. The processor to which the faulty message is directed is determined by a substitute destination processor number contained in the message or is predetermined and set in another way, such as by a service processor. To recover from the fault, the processor receiving the faulty message can request that the message be retransmitted or the error can be corrected using an ECC, for example. If the faulty message cannot be retransmitted, then the processor or the host processor can request that the job to which the faulty message pertains be canceled by all of the processors executing that job without affecting the simultaneous execution of other jobs by the same processors.
    • 并行处理器通过发送包含目标处理器信息的消息通过网络彼此进行通信。 用于网络中的每个处理器的消息控制器接收消息并检查消息中的故障,特别是在消息的第一个字中包含的目标处理器号码中。 如果目标处理器号码发生故障,则故障消息被传送到适当的处理器处理故障。 以这种方式,网络操作由于故障而不被暂停,并且由于目标处理器号码中出现错误,网络中没有留下该消息。 错误消息所针对的处理器由包含在消息中的替代目的地处理器号码确定,或者以另一种方式例如由服务处理器预先设定。 为了从故障中恢复,例如,接收到故障消息的处理器可以请求重传该消息或者使用ECC来纠正该错误。 如果故障消息不能重发,则处理器或主机处理器可以请求执行该作业的所有处理器取消与故障消息相关的作业,而不会影响同一处理器同时执行其他作业。

    • Reliability is evaluated in constructing a component based-on application and an application for realizing reliability required can be constructed efficiently. A run-time history such as an occurrence frequency of errors, a recovery time required at error occurrence, and a processing capacity at preventive maintenance is added per software component to a run-time history list having been recoded per execution environment such as an application ID, combined component IDs, and executed hardware ID. From these pieces of information, an interval of performing preventive maintenance recommended per software component during system construction is calculated. By comparing reliability per software component and reliability required for the system, advisability is determined and conformance is evaluated. An execution schedule for preventive maintenance and a processing capability are calculated about the entire component-based application created by combining the software components. By calculating the reliability and the processing capability in the entire system to be compared to those required for the entire system, advisability is determined and conformance is evaluated.
