    摘要: In an implementation of latent error detection, memory regions that each correspond to a different processor element of a redundant processor system are scanned for latent processing errors maintained as erroneous data. The data maintained in the memory regions is compared to detect a latent processing error in a first memory region. The latent processing error is resolved by copying data from a second memory region into the first memory region where the data maintained in the second memory region is determined to be identical to data maintained in at least a third memory region.

    摘要: A method and system of copying a memory area between processor elements for lock-step execution. At least some of the illustrative embodiments may be a method comprising executing duplicate copies of a first program in a first processor of a first multiprocessor computer system and in a first processor of a second multiprocessor computer system (the executing substantially in lock-step), executing a second program in a second processor element of the first multiprocessor computer system (the first and second processors of the first multiprocessor computer system sharing an input/output (I/O) bridge), copying a memory area of the second program executing in the second processor element of the first multiprocessor computer system to a memory of a second processor element in the second multiprocessor computer system while the duplicate copies of the first program are executing in the first processor elements, and then executing duplicate copies of the second program in the second processors in lock-step.

    摘要: Performance data access is described. In an embodiment, events are processed with non-synchronized processor elements of a logical processor in a redundant processor system. Performance data associated with execution of the processor events is stored in one or more accumulators corresponding to a respective processor element. The performance data from each of the non-synchronized processor elements is exchanged via a logical synchronization unit such that each processor element includes the performance data from each of the processor elements. Each processor element then conforms the performance data to generate synchronized performance data which is then communicated to a performance monitoring application that requests the performance data from the logical processor.
