Abstract

Each of processing nodes and switching apparatuses constituting a parallel processor system is provided with data transmitting/receiving apparatuses and The data transmitting/receiving apparatus in response to an instruction from a processor P within its own node, transmits data stored in a transfer data buffer to the data transmitting/receiving apparatus of a switching apparatus connected thereto. The data transmitting/receiving apparatus receives data that are transferred, and stores them into a transfer data buffer If any error in receive data is detected by an error detector of the data transmitting/receiving apparatus a retransmission request signal is issued from a retransmission control circuit to the retransmission control circuit of the transmitting apparatus The retransmission control circuit upon receiving the retransmission request signal instructs a data transmission control signal to execute retransmission. The data transmission control circuit causes the buffer control circuit to subtract an established value from a read pointer, and reads out of the transfer data buffer again and retransmits a single frame equivalent of data.
