Embodiment Construction

[0017] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

[0018] grid computing

[0019] figure 1 Describe the architecture of grid computing. There are various types of grids, but what is described here is a type called a desktop grid that executes jobs using the idle time of the CPU of a desktop PC or the like.

[0020] figure 1 The shown client PC inputs a job (S1) according to the instruction of the user, and the request (job) is transmitted to a task manager (hereinafter referred to as "TM"), and the TM transmits its content (job request) to a dynamic job scheduler ( Hereinafter abbreviated as "DJS") (S2). The DJS that manages the resources of the entire grid computing system selects a broker (broker) that is the most suitable resource and notifies it to the TM (S3). Here, the term "resource" refers to an idle state of the CPU of the PC.

[0021] The mediator of the PC registers in the DJS the in...

Abstract

By distributing a large amount of processing among multiple devices, the mechanism that seeks high-speed processing does not perform processing allocation that considers the hardware resources of the devices that perform the distributed processing. Therefore, the drawing in the printing job is distributed among the devices connected to the computer network. During processing, determine whether to perform hardware processing or software processing (S1102, S1103), search for an image processing device that can perform hardware rendering processing or software rendering processing (S1104, S1106) from devices connected to the computer network, and determine and The result of the search is notified to the device that sent the job divided from the print job (S1108).

Description

technical field [0001] The present invention relates to an information processing device and a control method thereof, and in particular to effective use of hardware resources such as an information processing device when a grid computing load distribution system is applied to a printer or a multi-function printing device connected to a computer network. Background technique [0002] There are many proposals for a configuration that achieves high-speed processing by distributing a large amount of processing among a plurality of devices. However, these proposals do not perform processing allocation that takes into account the hardware resources of devices that perform distributed processing. That is, as a target device for distributed processing that does not require hardware resources, a device having hardware resources may be used for the purpose of providing only its CPU capability. In this case, hardware resources are not used efficiently. content of the invention [...
