Abstract: A first communication device included in an information processing device stores, for each first identifier that is allocated for identifying a first packet, situation information indicating a second identifier that is allocated along with the first identifier, and updates the situation information on the basis of a reception result of a second packet indicating an execution result of processing that is requested by the first packet. Then, the first communication device determines the first identifier and the second identifier that are allocated to the first packet on the basis of the situation information and generates and transmits the first packet storing the first identifier and the second identifier that. A second communication device included in the information processing device transmits the second packet after storing the second identifier stored by the first packet in the second packet when transmitting the second packet as a response to the first packet.

Abstract: A PCIe processing unit is connected to a PCI device. A BDF information extracting unit specifies, in response to an occurrence notification of an error, a PCI device in which the error has occurred. An AER address searching unit detects the AER address that is the storage location of error information related to the error held by the PCI device specified by the BDF information extracting unit. An error information acquiring unit collects error information from the AER address that is stored in the PCI device and that is detected by the AER address searching unit. An interrupt determination unit transmits the error information collected by the error information acquiring unit to a core.
