摘要： A balancing process between I/O processor groups of a non-uniform multi-processor system enables spreading of I/O workload across multiple I/O processor groups on a group base as soon as the I/O processor group with maximum group utilization reaches a certain high limit together with other processor groups being utilized significantly lower. The additional balancing is decreased step by step again when a certain low utilization limit is reached or the workload becomes more evenly balanced between the I/O processor groups. Checking if increase or decrease of the balancing is required is done periodically, but with low frequency to not affect overall performance. The checking and balancing happens asynchronously in predefined intervals. This solves the problem that with an increasing number of I/O processors the handling of initiatives leads to increased cache traffic and contention due to shared data structures, which slows down the I/O workload handling significantly.
摘要翻译：一个不均匀多处理器系统的I / O处理器组之间的平衡过程使得一旦组利用率达到最大的I / O处理器组就可以在组上的多个I / O处理器组上扩展I / O工作负载与正在利用的其他处理器组相比，一定的上限明显降低。当达到一定的低利用率限制或I / O处理器组之间的工作量变得更加均衡时，额外的平衡将逐步减少。检查平衡的增减是否需要定期进行，但是频率低，不会影响整体性能。检查和平衡在预定义的间隔中异步发生。这解决了随着越来越多的I / O处理器的处理，由于共享的数据结构而导致的缓存流量和争用的增加，导致I / O工作负载处理显着减慢。
