Fault Tolerant Distributed Computation

摘要

The present information processing apparatus executes fault-tolerant distributed computing through a network and the information processing apparatus comprises: a finish initiator that creates a finish state on a home node; an activity creator that instructs to create at least one activity on a remote node; an activity launcher that allows to store in a resilient store a value indicating that at least one live activity is present on the remote node; an activity closer that decreases the number in the local memory when the living activity is completed and resets the value in the resilient store to indicate that no live activity is present on the remote node; and a finish closer that closes the finish state when the value stored in the resilient store indicates an absence of remote nodes having at least one live activity.

1. A method for fault-tolerant distributed computing that is executed by program codes tangibly stored in a memory of a computer node, the computer node being connected to a network for executing fault-tolerant distributed computing, the computer node executing the steps of:
creating a finish state on a home node; instructing creation of at least one activity on a remote node; creating the at least one activity on the remote node in response to the instructing step; storing in a resilient store a value indicating that at least one activity is live on the remote node; resetting the value in the resilient store when no activity is live on the remote node; and closing the finish state when the value stored in the resilient store indicates an absence of remote nodes having at least one live activity.
