System for utilizing a cache effectively

摘要

An information processing system of the present invention includes a data generation device that generates variable data, and a rendering device that performs rendering of the variable data. A first data storing unit of the data generation device stores, as a first correspondence relationship, the generated variable data and identification information for identifying the variable data in association with each other, and a first data management unit manages the first correspondence relationship based on a predetermined management scheme. A cache search unit searches for predetermined variable data from the first correspondence relationship, and a cache hit determination unit determines that rendering data obtained by performing rendering on the variable data is cached when there is predetermined variable data in the first correspondence relationship.

1. An information processing system comprising:
a first apparatus having at least one first processor and at least one first memory coupled to the at least one first processor; and a second apparatus having at least one second processor and at least one second memory coupled to the at least one second processor, wherein the at least one first memory has first instructions stored thereon which, when executed by the at least one first processor, cause the first apparatus to:
manage first management information for identifying objects whose rendered data has been stored in the at least one second memory,determine whether or not rendered data of a current object has been stored in the at least one second memory, based on the first management information, andinstruct the second apparatus to acquire the rendered data of the current object being stored in the at least one second memory, if a determination is made that the rendered data of the current object has been stored in the at least one second memory, and wherein the at least one second memory has second instructions stored thereon which, when executed by the at least one second processor, cause the second apparatus to:
manage second management information for identifying rendered data of the objects being stored in the at least one second memory, andacquire the rendered data of the current object being stored in the at least one second memory by using the second management information according to the instruction, wherein the first management information and the second management information are updated so that the rendered data of the objects which are identified by the first management information is identified by the second management information.
