摘要： An approach to detecting processor failure in a multi-processor environment is disclosed. The approach may include having each CPU in the system responsible for monitoring another CPU in the system. A CPUn reads a timestampn+1 created by CPUn+1 which CPUn is monitoring from a shared memory location. The CPUn reads its own timestampn and compares the two timestamps to calculate a delta value. If the delta value is above a threshold, the CPUn determines that CPUn+1 has failed and initiates error handling for the CPUs in the system. One CPU may be designated a master CPU, and be responsible for beginning the error handling process. In such embodiments, the CPUn may initiate error handling by notifying the master CPU that CPUn+1 has failed. If CPUn+1 is the master CPU, the CPUn may take additional steps to initiate error handling, and may broadcast a non-critical interrupt to all CPUs, triggering error handling.
摘要翻译： 公开了一种在多处理器环境中检测处理器故障的方法。 该方法可以包括使系统中的每个CPU负责监视系统中的另一个CPU。 CPUn读取CPUn + 1创建的时间戳+1，CPUn正在从共享内存位置进行监控。 CPUn读取自己的时间戳，并比较两个时间戳来计算增量值。 如果增量值高于阈值，CPUn确定CPUn + 1失败，并启动系统中CPU的错误处理。 一个CPU可能被指定为主CPU，并负责开始错误处理过程。 在这种实施例中，CPUn可以通过通知主CPU CPUn + 1失败来启动错误处理。 如果CPUn + 1是主CPU，CPUn可能会采取额外的步骤来启动错误处理，并可能会向所有CPU广播非关键中断，从而触发错误处理。

摘要： Provided are a computer program product, system, and method for determining processor offsets to synchronize processor time values. A determination is made of a master processor offset from one of a plurality of time values of the master processor and a time value of one of the slave processors. A determination is made of slave processor offsets, wherein each slave processor offset is determined from the master processor offset, one of the time values of the master processor, and a time value of the slave processor. A current time value of the master processor is adjusted by the master processor offset. A current time value of each of the slave processors is adjusted by the slave processor offset for the slave processor whose time value is being adjusted.

摘要： Provided are a computer program product, system, and method for locking a cache line for a burst write operations on a bus. A cache line is allocated in a cache for a target address. A lock is set for the cache line, wherein setting the lock prevents the data in the cache line from being cast out. Data is written to the cache line. All the data in the cache line is flushed to the target address over a bus in response to completing writing to the cache line.

摘要： Provided are a method, system, and computer program product for managing monitored conditions in adaptors. An adaptor detects a condition comprising one of a plurality of monitored conditions and determines whether the detected condition is indicated on a recent condition list indicating conditions detected at the adaptors. The adaptor communicates the detected condition to cause the detected condition to be included in the recent condition list available at the adaptors in response to determining that the detected condition is not indicated in the recent condition list. Further, a system receives from one of the adaptors indication of a detected condition comprising one of a plurality of monitored conditions that is not indicated on a recent condition list. The received indicated condition is added to the recent condition list to produce an updated recent condition list. Transmission is caused of the updated recent condition list to the adaptors.
