Abstract:
In a computer system including a job scheduler which divides an input job and determines a client apparatus to assign the divided job, and a task manager which transmits the divided job to the client apparatus determined by the job scheduler, the job scheduler assigns the same job to a plurality of client apparatuses when the number of client apparatuses is larger than the number of divided jobs, and when the job is finished in one of the plurality of client apparatuses assigned the same job, execution of the job in the remaining client apparatuses is canceled so that the time until all jobs are finished is shortened.
Abstract:
When a packet received in a deep sleep mode matches a packet stored in a WOL-pattern storage region, a network portion performs reply processing suited for the matched packet after returning a power supply mode of a power supply unit from the deep sleep mode to a normal mode. When the packet received in the deep sleep mode matches a packet stored in a proxy-response-pattern storage region, the network portion performs reply processing suited for the matched packet while maintaining the power supply mode of the power supply unit at the deep sleep mode.
Abstract:
When the distributed load system of grid computing is applied to printers, multi-functional peripheral equipments, and the like connected to a computer network, if a device which inputs a job received from the client is executing processing, the distributed processing requires much time, and the user of the client cannot obtain the print result soon. Hence, when a print job is input, the processing time upon executing distributed processing of data processes in the print job by computer devices connected to the computer network is estimated. Based on the estimation result, the print job or jobs divided from the print job are transmitted to the computer devices connected to the computer network.
Abstract:
When a target device of distributed processing has shifted to a power save mode, if the target device is resumed to the normal operation to attain the distributed processing, resources of the target device which are not required for the distributed processing waste electric power. Therefore, when a print job to be processed by grid processing is received, resources required for the grid processing from resources in a waiting state, and the grid processing is executed to process the received print job.
Abstract:
The invention provides a network system which can prevent an illegal access to a network or the like set in a specific area and improve security of the network. The network system permits the entering of the user into a security area in accordance with security information (user ID) read out of a contactless IC in a carrying ID card by an entering/leaving room managing apparatus and registers an MAC address of a notebook computer carried by the user when he enters the security area to a managing server as ID information corresponding to the user ID. When a leaving request of the user is received through the entering/leaving room managing apparatus, the network system deletes the registered ID information and restricts connection between the notebook computer and the network on the basis of a registration situation of the ID information to the managing server.

Abstract:
The present invention provides an image processing apparatus, a method of controlling the image processing apparatus, a program and a storage medium that can increase security strength of encoded data, printed on a recording medium. According to an embodiment of the present invention, an image to be a document is read and is subjected to image processing, and thereby digital data is acquired. Next, the above-described digital data is encoded to generate a first encoded data. Next, information on a process of decoding the digital data from the first encoded data is encoded to generate second encoded data.
Abstract:
In a network print system in which a printer and at least one client are connected to each other through a network, and at least a part of a job for the printer can be subjected to load distributed processing by grid computing, wherein when a printer driver of the printer is installed on any one of the at least one client, the system is adapted to build a grid computing network. In this arrangement, it is easily to build the grid computing network in which the printer job is subjected to load distributed processing.
