    Patent number: 6434630
    Abstract: An input/output (I/O) controller in an I/O system processes I/O requests from a host computer to a plurality of I/O devices. The I/O controller generates an interrupt to the host computer and reports a plurality of completed I/O requests from the I/O devices when at least one condition of the I/O system is met. A first condition of the I/O system comprises a predetermined ratio between the total number of unreported I/O completions by the I/O devices and the total number of remaining I/O requests from the host computer. A second condition comprises the expiration of a timer, which starts when the number of remaining I/O requests left to process for any individual I/O device reaches a predetermined minimum limit.
