摘要： 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.

摘要： A receiving buffer control system comprises a memory having a buffer area serving as a receiving buffer, data being applied to the memory via a bus, a write pointer indicating a write address of the buffer area, and a read pointer indicating a read address of the buffer area. An overrun/underrun detection circuit detects a situation in which an overrun or an underrun will occur in the buffer area in response to the write address indicated by the write pointer and the read address indicated by the read pointer. A control part disables the data from being written into and read out from the buffer area when the overrun/underrun detection circuit detects the situation.

摘要： When the processor writes a command data string into an address of the command entry area, a corresponding command is created by a bus interface. If an address output by the processor corresponds to a distributed shared memory area, the bus interface creates a remote access command. The send controller constructs a message based on the command created by the bus interface. This message is sent either to an interconnection network, or to a receive controller. The receive controller receives the message and interprets it. An address output by the processor is detected by a cache area access unit, and the cache area in the memory is accessed. When the processor receives an interrupt request while waiting for a response message to a remote read request, an deadlock control unit detects an abnormal end of the remote read request that the remote read has ended in an error, and, controls the processor to process the interrupt request with priority.

摘要： A message receiving method communicates a message among a plurality of computers in a parallel computer system, shortens a delay time in storing a received message in a user area of a memory, and realizes overlap between receipt of a message and execution by a processor. Each computer in the parallel computer system comprises a message buffer for temporarily storing the received message and a message handler for receiving a receive-a-message request from a processor of a computer to which it belongs. If the receive-a-message request arrives before the arrival of the message, the message handler directly transmits the received message to a user area specified by the receive-a-message request. During the transmission period, the message handler prevents the processor from accessing a portion in the user area to which the message has not been transmitted yet.

摘要： A communication control system controls communication between parallel computers using a wormhole routing. The system comprises units for connecting a plurality of computer nodes by relay channels within a network to continuously transfer a message divided into a plurality of minimum data units for transmission. Storing units are provided in respective nodes for storing the minimum data units, the number of storing units corresponding to the number of relay channels from the originating node to the most remote node plus 1. Therefore, a deadlock in a communication is avoided, and a high speed communication can be realized.

摘要： 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.

摘要： 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.
