Abstract
The distributed memory type multiprocessor computing system according to the present invention includes a plurality of nodes which are coupled with each other so as to correspond to a tree construction by communicating switches. Each of nodes acquires checkpoints at a predetermined time for reexecuting the respective data processing from a previously acquired checkpoint when a fault occurred. Each of nodes starts the checkpoint acquisition in synchronous with all another nodes by prohibiting data transfer through the communication switch to another nodes and by making completion of data reception through the communication switch for keeping vacant state which no data exist in the communication switch.
