Patent ID: 8775679

Claim:
A device for issuing a synchronization message in a large-scaled computing system performing a plurality of types of computing processes as a parallel processing including an interconnect that includes a plurality of switches connected to each other, and a plurality of computing devices performing the plurality of types of computing processes and being connected to the interconnect, wherein the device sends a synchronization message including a set value, which is incremented every time the device sends a synchronization message, for synchronizing the computing processes of one of the plurality of types of computing processes on the computing devices, to all the computing devices at same timing via the switches that are directly connected to any of the computing devices by using a protocol for the interconnect, the synchronization message with a predetermined set value being associated with the computing processes of the plurality of types of computing processes to be performed on the computing devices, the one of the plurality of types of computing processes being a housekeeping process, the housekeeping process being a process performed as a periodic system activity and whose execution causes a temporal and random stoppage of execution of an application.
