Information processing system, information processing device, data transfer device, and information processing system control method

摘要

A processing system includes a first processing device and a switch device. The first processing device includes a first transmitter configured to transmit a plurality of packets, and a controller configured to acquire first time information indicating a first time at which the transmitting of the plurality of packets started. The switch device includes a first receiver configured to receive at least one of the plurality of packets transmitted from the first processing device and receive the first time information from the first processing device, a second transmitter configured to acquire second time information indicating a second time at which a link-up occurred, compare the second time information with the first time information, and perform a notification to a second processing device of occurrence of error in transmitting of the plurality of packets when the second time is later than the first time.

主权项

1. A processing system, comprising:
a first processing device; a switch device coupled to the first processing device; and a second processing device coupled to the switch device, wherein the first processing device is configured to:
divide data into a plurality of packets,transmit a start packet indicating a first packet among the plurality of packets to the switch device,acquire a transmitting start time indicating a time when the start packet was transmitted from the first processing device,transmit one or more intermediate packets among the plurality of packets to the switch device, according to an order of the one or more intermediate packets, andtransmit a final packet indicating a last packet among the plurality of packets to the switch device, the final packet having information of the transmitting start time of the start packet, wherein the switch device is configured to:
transfer the start packet and the one or more intermediate packets to the second processing device,extract the transmitting start time from the final packet when the final packet is received,acquire a link-up time indicating a time when a final link-up occurred between the first processing device and the second processing device, based on a timing of receiving or transferring of the start packet and the one or more intermediate packets, andsuppress performing a process using the plurality of packets to be executed by the second processing device, when the acquired link-up time is later than the extracted transmitting start time.
