摘要：
In a multinode data processing system in which data is transferred, via direct memory access (DMA) or in remote direct memory access (RDMA), from a source node to at least one destination node through communication adapters coupling each node to a network or switch, a method is provided in which interrupt handling is overlapped with data transfer so as to allow interrupt processing overhead to run in parallel at the destination node with the movement of data to provide performance benefits. The method is also applicable to situations involving multiple interrupt levels corresponding to multithreaded handling capabilities.
