Abstract: A task management system is configured to store a consumption resource amount transition prediction of a resource consumed by tasks, and effective resource amount information for managing an effective resource amount indicating a total resource amount that is providable from the resource. The task management system is configured to, for the resource consumed by each of the tasks, compare a consumption resource amount prediction obtained from the consumption resource amount transition prediction with a current consumption resource amount, determine that the effective resource amount of the resource is decreased when a predetermined condition including that the current consumption resource amount is smaller than the consumption resource amount prediction is satisfied, estimate a decrease amount of the effective resource amount based on a difference between the current consumption resource amount and the consumption resource amount prediction, and determine an influence on task execution based on the decrease amount.

Abstract: The information system of the present invention is composed of multiple sites including a local file server and clients, and a data center having a center file server. When a user starts moving to a different site after using a file in the local file server through a client of any one site, the local file server replicates files of a user having the shortest predicted arrival site to a different site to a center file server preferentially based on a location information of each user. Further, at each site, files of a user having a short predicted time of arrival to its own site are downloaded based on the location information of the user.

Abstract: There is provided a storage system that can avoid an increase in inter-node communication in the cooperation between file service and block service. The storage system includes a management section that manages a file processing section of a node in a currently active system and a file processing section of a node in a standby system as a pair, sets the file processing section of the node in the currently active system to be operational, manages a block processing section of the node in the currently active system and a block processing section of the node in the standby system as a pair, and sets the block processing section of the node in the currently active system to be operational.
