Parallel computing system, synchronization device, and control method of parallel computing system

摘要

A synchronization device includes a receiver that receives data from at least two synchronization devices establishing synchronization, and extracts synchronization information and register selection information from the received data, a transmitter that transmits data to each of the at least two synchronization devices establishing synchronization among a plurality of synchronization devices, a first and a second receiving state register that each stores the extracted synchronization information, a second receiving state register that stores the extracted synchronization information, and a controller that stores the extracted synchronization information into the first receiving state register and the second receiving state register alternately based on the register selection information, and controls the transmitter to transmit data including the register selection information to each of the at least two synchronization devices when the extracted synchronization information is completed in one of the first and the second receiving state register.
