20090187619 | RECORDING MEDIUM HAVING DISTRIBUTED PROCESSING PROGRAM STORED THEREIN, DISTRIBUTED PROCESSING DEVICE AND DISTRIBUTED PROCESSING METHOD - A computer executes a distributed processing program. The computer is a master computer that uses communicable worker computers to execute distributed processing on plural jobs. The computer determines an allocation destination of the jobs from the worker computers. The computer calculates the number of jobs to be allocated to the allocation destination based on the processing performance and the communication time (delay time) taken for communications with a worker computer. The computer generates a job group to be allocated to the allocation destination on the basis of a calculation result obtained. The computer transmits a processing request of the generated job group to the allocation destination. | 07-23-2009 |
20090187907 | RECORDING MEDIUM IN WHICH DISTRIBUTED PROCESSING PROGRAM IS STORED, DISTRIBUTED PROCESSING APPARATUS, AND DISTRIBUTED PROCESSING METHOD - A master calculator assigns a series of processing groups to a communicable worker calculator. The master receives information about an execution time and a waiting time from the worker calculator for the series of processing groups. The computer acquires the time elapsed between transmitting the processing group transmitted to the worker calculator and receiving the execution result of the processing group from the worker calculator. The master calculates the communication time required for communication with the worker calculator on the basis of the information received and the elapsed time acquired. The master calculates the number of processings to be assigned to the worker calculator on the basis of the communication time calculated. The master generates a processing group to be assigned to the worker calculator on the basis of the number of processings calculated, and transmits the processing group generated to the worker calculator. | 07-23-2009 |
20100008374 | RELAY APPARATUS, RELAY PROGRAM, RELAY METHOD, AND MANAGEMENT SYSTEM FOR MANAGING DEVICES CONNECTED TO NETWORK - A relay apparatus includes: a tag information acquisition section that acquires tag information attached to the network-connected device; a management section that manages the tag information read out by the tag information acquisition section and an IP address assigned by the management apparatus, and an identification information assigned to the relay apparatus itself in association with one another; and a processing section that receives information that the management apparatus has transmitted with the tag information or IP address as a transmission destination and receives information transmitted from the network-connected device for execution of predetermined processing. | 01-14-2010 |
20100100880 | VIRTUAL SYSTEM CONTROL METHOD AND APPARATUS - A virtual system control apparatus includes a configuration information storage device that stores configuration information for operational systems of virtual systems; a first virtual machine image storage device that stores virtual machine images for the operational systems of the virtual systems; a configuration change information storage device that stores configuration change information that represents configuration information concerning difference between the operational system and a test system of the virtual system; a second virtual machine image storage device that stores virtual machine images for the virtual machine relating to the difference; and a controller. Thus, by adopting data configuration of the operational system and the test system, it becomes possible to easily and smoothly switch the virtual system between the operational system and the test system. | 04-22-2010 |
20100100881 | VIRTUAL SYSTEM CONTROL METHOD AND APPARATUS - A virtual system control apparatus includes: a configuration information storage device to store configuration information for an operational system of a virtual system; a first virtual machine image storage device to store first virtual machine images for the operational system of the virtual system; a configuration change information storage device to store configuration change information that represents configuration information concerning difference between the operational system of the virtual system and plural types of test systems; a second virtual machine image storage device to store second virtual machine images for a virtual machine relating to the difference; and a controller. By adopting such data configuration of the operational system and the test system, it becomes possible to switch easily and smoothly between the operational system and the test system. | 04-22-2010 |
20100115342 | SYSTEM EVALUATION APPARATUS - An apparatus for evaluating a change of an existing system to a modified system by using a test system including a subsystem having the same configuration with either of the existing subsystem and the modified system includes: a memory for storing configuration information of the test system and test information; and a processor for executing a process including: activating the test system to execute test on the subsystem, collecting test information from the test system, and storing the test result information while the subsystem has the same configuration as the existing system; confirming the test system has been modified; and activating the test system to execute test on the subsystem, collecting test result information from the test system, and storing the test result information while the subsystem has the same configuration as the modified system. | 05-06-2010 |
20100125550 | COMPUTER-READABLE MEDIUM STORING DATA SHARING PROGRAM, DATA SHARING METHOD, AND DATA SHARING PROCESSOR - Each of plurality of nodes connected to each other via a network includes a local instance processor and a user application processor. The local instance processor executes a data sharing method for accessing shared data. The data sharing method includes: storing a value of first shared data with a function identifier of an update function upon receiving a registration request, wherein the update function is commutative and idempotent; updating the stored value of the first shared data to a first update value in accordance with an execution result of the update function upon receiving an update request; returning a completion message upon updating the stored value of the first shared data stored in the first node; and transmitting a first reflection request to a second node upon updating the stored value of the first shared data stored in the first node. | 05-20-2010 |
20100250715 | RECORDING MEDIUM THAT STORES INTERNET-PROTOCOL (IP) ADDRESS ASSIGNMENT CONTROL PROGRAM, IP ADDRESS ASSIGNMENT CONTROL APPARATUS, AND IP ADDRESS ASSIGNMENT CONTROL METHOD - An internet-protocol address assignment control apparatus obtains, via an interface provided in a first communication device, a first unique number for a first interface provided in a server apparatus connected to the interface provided in the first communication device and a second unique number for a second interface provided in the server apparatus connected to an interface provided in a second communication device. The apparatus stores, in a storage, the obtained second unique number for the second interface provided in the server apparatus on a basis of the first unique number for the first interface provided in the server apparatus. | 09-30-2010 |
20130081015 | STORAGE SYSTEM - The I/O performance measurement unit of Hypervisor measures latencies of I/O process requests to virtual disks, and reports the average value of the latencies to the I/O performance information collection unit of the management server. The provision destination determination unit sets, as a storage unit to which a virtual disk is to be allocated, that is a storage unit having the smallest average value of the latencies among storage units to which virtual disks have been provided. | 03-28-2013 |
