The purpose of the present invention is, in a file storage, to shorten an access response time to shared data. When a file storage apparatus receives a command for a specific manipulation of a file system, a specific apparatus determines, based on a state of the file system and a manipulation history, whether or not an unapplied manipulation affects a target of the specific manipulation, the unapplied manipulation being a manipulation which has been previously executed by another file storage apparatus among a plurality of file storage apparatuses and which has not been applied to the file system. When it is determined that the unapplied manipulation affects the target of the specific manipulation, the file storage apparatus applies the unapplied manipulation to the file system, executes the specific manipulation on the file system, and transmits, to a cloud storage apparatus, manipulation information which represents the specific manipulation.

Computer system, file storage apparatus, and storage control method

The present invention relates to a distributed processing system having a master node and a plurality of worker nodes. Each worker node has an assigned identifier. A worker node caches in its own memory first output data, which is the result of the execution of a first task, and copies said first output data to another worker node. The master node selects, on the basis of the identifier information of the first worker node, a worker node to which to assign a second task, wherein the first output data is used as input data.

Distributed processing system, task processing method, and storage medium

A progress status management system comprises a management target system configured to execute a series of processes to the file, which includes a plurality of process units configured to execute a process to a file, and a progress status management unit configured to manage a progress status of a process executed by the process unit included at the management target system. The progress status management unit, in a case of acquiring the first identification information of a file in a first process unit, acquires the first identification information of the file in the second process unit, and links the acquired first identification information in the first process unit and the acquired first identification information in the second process unit to the same second identification information.

Progress status management system and progress status management method

This object is aimed to provide an advertisement providing system, etc. that defines a web API that contributes to the creation of an advertisement attached webpage for making it possible to distribute referral fees of the advertisement. A system carries out processing while taking a session ID generated by an advertisement intermediary service () among a website (), a web API () and the advertisement intermediary service (), wherein the website () creates a webpage including a result of processing by the web API (), a link for acquiring a resource of advertisement information, and a link having as a parameter a session ID which is called on selection of an advertisement. And returns the webpage to a web browser (), and the advertisement intermediary service () records an advertisement information request in association with the session ID when the web browser () requests the advertisement intermediary service () for an advertisement information resource and then returns the advertisement information resource to the web browser (), thereby attaining the object.
