A disclosed information processing method is executed in a distributed processing system that processes data by plural information processing apparatuses. And the information processing method includes: obtaining, by a first information processing apparatus of the plural information processing apparatuses and from a second information processing apparatus that manages relations among data, identification information of first data that has a predetermined relation with second data and identification information of an information processing apparatus that manages the first data, upon detecting access to the second data managed by the first information processing apparatus; reading out, by the first information processing apparatus, the first data, upon determining that the information processing apparatus that manages the first data corresponds to the first information processing apparatus; and loading, by the first information processing apparatus, the first data into a cache.

Method and system for caching data managed by plural information processing apparatuses

An information processing apparatus includes a receiving unit that receives an access request for data from one of a plurality of information processing apparatuses in a distributed processing system in which the information processing apparatuses execute a process in a distributed manner, a query issuing unit that issues, when the access request for the data is received by the receiving unit, a query to each of the information processing apparatuses as to whether the data is stored in a page cache managed by an operating system on each of the information processing apparatuses, and a responding unit that makes a response to the access request, the response specifying, as an access destination, an information processing apparatus that has responded to the query issued by the query issuing unit.

Information processing apparatus, distributed processing system, and distributed processing method

An information processing device includes a memory and a processor coupled to the memory, wherein the processor executes a process comprising selecting data included in a same file as deletion target data from the memory when deleting the data cached in the memory at the caching from the memory and deleting the deletion target data and the data selected at the selecting, from the memory.

Information processing device, memory management method, and computer-readable recording medium

A data transfer method for transferring, through use of a plurality of paths, data between a plurality of logic devices provided in an external storage device and an input/output request device which issues input/output requests to the respective logic devices of the external storage device. The method includes a first step for setting priority levels of the plurality of logic devices; a second step for setting usage rates of the paths for the respective logic devices on the basis of the priority levels set in the first step; and a third step for transferring the data through use of respective paths such that the usage rates set in the second step are achieved.
