  • Publication number: 20210042128
    Abstract: An information processing system includes information processors and a relay device. Each of the information processors includes a first communication device to transmit a reset signal representing initialization and to transmit/receive data. The relay device includes an input device and a hardware processor. The input device receives the reset signal from each of the information processors with bypassing second communication devices of the relay device. When the input device receives the reset signal, the hardware processor executes initialization processing of initializing one of the second communication devices that corresponds to one of the information processors serving as a transmission source of the data. The initialization processing is executed on a condition that one of the information processors, from which the reset signal has been transmitted, receives the data via a connection device.

  • Publication number: 20200364153
    Abstract: A relay device includes end points to relay communication among information processing devices having root complexes connected to the end points. The relay device includes a hardware processor and circuitry. The hardware processor requests one of the devices to set an address space used to access a setting area for the one of the devices. The setting areas are areas in which access information for accessing public areas on memory spaces of the devices are set. The circuitry translates an address input from the one of the devices, based on a translation rule in which an address of the requested address space has been correlated with an address of the setting area for the one of the devices. The translation rule is stored in an area in which the devices are prohibited from performing rewriting.

  • Publication number: 20200341928
    Abstract: In an information processing system, a first relay device includes first address ranges corresponding to first connection units of the first relay device connected to first information processing devices, and second address ranges corresponding to second connection units of a second relay device connected to second information processing devices, and transfers data for which a second address range is designated, from the first relay device to the second relay device. The second relay device includes third address ranges corresponding to the second connection units and fourth address ranges corresponding to the first connection units. When transferring data for which a second address range is designated, from the first relay device to the second relay device, the first relay device converts address information relating to the data to address information for designating a third address range and transfers the resultant address information to the second relay device.
