Abstract
Each node includes a cache to store data of the storage shared by the plurality nodes. Time information when a process accessing to data migrates from one node to another node is recorded. The one node, after migration of the process to the other node, selectively invalidates data held in the cache of the one node with a time of last access thereto by the process on the one node being older than a time of migration of the process from the one node to the other node.
