  • Patent number: 10021269
    Abstract: A read sensor generates front side image information indicating an image on a front side of an object to be read, and front side measurement information indicating a line of an image in a main scanning direction on the front side of a correction chart. A read sensor generates back side image information indicating an image on a back side of the object to be read, and back side measurement information indicating a line of an image in the main scanning direction on the back side of the correction chart. The image correction device calculates an amount of misalignment of read positions based on the front side measurement information and the back side measurement information, and corrects misalignment of images on the front side and the back side of the object to be read, indicated by the front side image information and the back side image information.

  • Patent number: 8180842
    Abstract: A communication device management program that enables efficient use of memory space in receiving data using remote direct memory access (RDMA) techniques. The receiving node transmits a virtual ID corresponding to a receiving process to a remote sending node. A sending process in the sending node specifies this virtual ID when starting data transmission. If the receiving node has not reserved a memory area corresponding to that virtual ID, the sending node transmits a reservation request to the receiving node, which causes a data receiving memory area to be reserved for use by a communication device in the receiving node. In the sending node, the sending communication device begins sending transmission data in RDMA mode, from a memory area managed by the sending process to the reserved data receiving memory area. The receiving communication device directs incoming transmission data to a memory area managed by the receiving process.

  • Patent number: 8074222
    Abstract: In a job management device: a request reception unit stores job-input information in a storage device on receipt of a job-execution request; and an execution instruction unit sends to one or more job-assigned calculation nodes a job-execution instruction together with execution-resource information, and stores job-assignment information in the storage device in association with a job identifier. When the contents of the job database are lost by a restart of the job management device, a reconstruction unit collects the job-input information and the job-assignment information from the storage device, collects the execution-resource information from the one or more job-assigned calculation nodes, and reconstructs the job information in the job database.

  • Patent number: 7768905
    Abstract: To prevent communication between processes of different computers from being interrupted due to a trouble in one transmission route. A communication controller of a computer selects at least one of communication devices and establishes physical connections via the selected communication devices, in response to a connection request from a prescribed process. The communication controller defines the one or more established physical connections as a logical connection. When a trouble happens in a physical connection included in the logical connection, the communication controller establishes another physical connection via a communication device different from that of the troubled physical connection and includes this physical connection in the logical connection. When receiving a communication request applied to the logical connection, from the process, the communication controller performs communication via the physical connections included in the logical connection, in response to the communication request.

  • Patent number: 6484249
    Abstract: An apparatus and method for efficiently transferring a plurality of segmented data with various sizes. An address translation storage unit stores an address translation table which provides a plurality of translation descriptor domains to support a plurality of translation step sizes. Depending on the segment size of each data block to be transferred, a translation descriptor domain selection unit chooses a suitable translation descriptor domain within the address translation table. Data segment mapping is then performed with translation descriptors in the selected translation descriptor domain.
