摘要： A process stop method and apparatus applicable to a distributed memory multi-processor system allows an efficient stop processing for the entry of a checkpoint during parallel processing where data are communicated between different nodes. The system comprises a plurality of nodes interconnected through a network, each of which is provided with a thread for parallel processing. Each of the nodes has a management process to manage its own thread engaged in parallel processing. When a request for a checkpoint is dispatched as an external command, the management process of a node whose node number is the smallest requests a stop from the thread of the same node. After confirming that the thread in question has stopped, the management process delivers a stop request to the management process of a node whose node number is the next smallest. Thus, the management process of a given node delivers a stop request to its own thread and another stop request to the management process of a node whose node number is the next smallest. The same process is repeated sequentially in an ascending order until all the nodes involved in parallel processing make a complete stop.
