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.

Abstract: A rotor blade includes a shroud cover which is formed at a first end portion of a blade body. The shroud cover extends in a first direction separating away from a camber line of the blade body. The shroud cover includes a gas path surface exposed toward a second side in the blade height direction and a back surface exposed toward a first side in a blade height direction. The gas path surface includes a fillet surface which gradually extends toward the first side as it goes from each of a pressure surface and a suction surface of the blade body toward the first direction in a cross-section orthogonal to the camber line. The back surface is opposite to the gas path surface, and includes a recessed surface which extends so as to be recessed toward the second side along the fillet surface in the cross-section.

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.
