    • A computer network system and a method for fast delivery of an interrupt message over a computer network enables a first processor coupled to the computer network to very quickly send an interrupt message to a second processor coupled to the computer network, by directly writing the interrupt message to a doorbell address range associated with the second processor in the PCI memory space of a first PCI bus to which the first processor is coupled. The doorbell address range is mapped to a doorbell space in the PCI memory space of a second PCI bus to which the second processor is coupled. The first PCI bus is coupled to the computer network through a first PCI network adaptor, which processes the write transaction and send it to the network. The second PCI bus is coupled to the computer network through a second PCI network adaptor, which receives the write transaction from the network and transforms the write transaction into an interrupt message to the second processor.

    • A PCI (peripheral component interconnect) network adaptor manages read/write requests through the establishment of dynamic queues. The PCI network adaptor establishes a unique queue for each destination node that enables the requests for each node to be processed separately. The PCI network adaptor determines whether a remote read/write request should be added to the linked list for the destination node of the request or whether the request should be rejected. If the number of pending requests for the destination node is below a predetermined threshold and the entire buffer is not full, then the request is added to the linked list for the destination node. Otherwise, the request is rejected. For write requests, if the request is added to the linked list for the destination node, then any pending read requests for that node are aborted.
    • PCI(外围组件互连)网络适配器通过建立动态队列来管理读/写请求。 PCI网络适配器为每个目标节点建立一个唯一的队列,使每个节点的请求能够单独处理。 PCI网络适配器确定是否应将远程读/写请求添加到请求的目标节点的链接列表中,还是请求被拒绝。 如果目的地节点的未决请求数量低于预定阈值并且整个缓冲器未满,则将该请求添加到目的地节点的链表。 否则,请求被拒绝。 对于写入请求,如果将请求添加到目标节点的链接列表,则该节点的任何未决读取请求将被中止。

    • An overflow control unit stores, in a FIFO buffer, data generated by a processor. The overflow control unit sets a predetermined flag, upon detecting that a FIFO buffer is full or nearly full. The overflow control unit stores, in a saving buffer, data sent from the processor, while the flag is set. Thereafter, the overflow control unit notifies the processor, by an interrupt, of an effect that an available capacity of the FIFO buffer rises above a predetermined threshold.Upon receiving an interrupt, the processor transfers to the FIFO buffer data saved in the saving buffer. Upon a completion of transferring to the FIFO buffer all data saved in the saving buffer, the processor resets the flag. This allows the overflow control unit to again store in the FIFO buffer, data sent from the processor. The overflow control unit also monitors the volume of data stored in the saving buffer, and notifies the processor, by an interrupt, of an effect that the saving buffer is full. Upon receiving an interrupt, the processor expands an available capacity of the saving buffer.
    • 溢出控制单元在FIFO缓冲器中存储由处理器生成的数据。 检测到FIFO缓冲器已满或接近满时,溢出控制单元设置预定标志。 在保存缓冲器中,溢出控制单元在设置标志时存储从处理器发送的数据。 此后,溢出控制单元通过中断通知处理器FIFO缓冲器的可用容量上升到预定阈值以上的效果。 在接收到中断时,处理器将传输到保存在保存缓冲区中的FIFO缓冲区数据。 在完成向FIFO缓冲区传送保存在保存缓冲区中的所有数据后,处理器重置标志。 这允许溢出控制单元再次存储在FIFO缓冲器中,从处理器发送的数据。 溢出控制单元还监视存储在保存缓冲器中的数据量,并通过中断向处理器通知保存缓冲器已满的效果。 在接收到中断时,处理器扩展了保存缓冲区的可用容量。
