Patent number: 8166484Abstract: For a resource reservation in a distributed resource system, a tentative reservation request and a job reservation request are issued from a job scheduler to a resource management unit. The tentative reservation is valid for a short time period, and cannot coexist with another tentative reservation or the job reservation. In order to actually use resources, a job reservation must be issued after registration of the tentative reservation. If a tentative reservation request is received for a resource to which another tentative reservation request is already accepted, the tentative reservation request is stored in a wait queue, which is successful if the another tentative reservation is cancelled or failed due to the expiration of the validity time period.Type: GrantFiled: March 19, 2004Date of Patent: April 24, 2012Assignee: NEC CorporationInventor: Masahiro Kawato

Patent number: 8112527Abstract: A virtual machine management apparatus connected to a plurality of server devices via a network generates a new virtual machine on a server device in accordance with a request from a management terminal. At that time, for one or more server devices to which a new virtual machine can be allocated, the virtual machine management apparatus refers to an allocation rule table for storing a score for each of combinations of types of virtual machines. The score indicates appropriateness of a condition that each combination of types of virtual machines is to be allocated to the same server device. Thus, the virtual machine management apparatus computes an index value indicative of appropriateness of a condition that the new virtual machine is to be allocated to the server device. Then the virtual machine management apparatus determines an allocation target for the new virtual machine with reference to the computed index value.Type: GrantFiled: May 15, 2007Date of Patent: February 7, 2012Assignee: NEC CorporationInventor: Masahiro Kawato

Patent number: 8099509Abstract: [Means for Solution] Access-control-rule application means (310), upon receiving an access request, refers to an access control rule DB (350) and resource information DB (360), to judge whether the attribute of a rule matched with the request is permitted, denied, or manual approval. The access-control-rule application means (310) requests manual-access-control application means (320) to input a result of approval, if the attribute is manual approval. The manual-access-control application means (320) inputs the result of approval input from a resource administrator's terminal (104) into access-control-rule application means (310), which outputs the result of approval.Type: GrantFiled: January 24, 2006Date of Patent: January 17, 2012Assignee: NEC CorporationInventor: Masahiro Kawato

Patent number: 8024740Abstract: In a resource acquisition system, computing resources are located in different domains, and a resource manager is located in each domain. A scheduler receives a resource acquisition request from a client via a network, and determines at least one administrative domain and transmits to the network a verification request specifying a computing resource and an operation. The resource manager is responsive to the verification request for performing reconfiguration of the specified resource according to the specified operation and verifying that the resource is legitimately reconfigurable, and transmitting back to the scheduler a verification report containing the identifier of the reconfigurable resource. The scheduler is responsive to the verification report for transmitting a reconfiguration request to the resource manager to perform reconfiguration on the verified resource.Type: GrantFiled: March 16, 2005Date of Patent: September 20, 2011Assignee: NEC CorporationInventor: Masahiro Kawato

Patent number: 7930398Abstract: In a distributed computing system, an end terminal transmits a job execution request to a job scheduler, which in response determines a resource and a job execution period necessary for executing a job on the resource based on contents of the job indicated in the message. A reservation request message containing the job execution period and the resource identity is sent from the job scheduler to a target resource proxy. The resource proxy determines a scheduled period of the resource based on the job execution period by checking its schedule memory, and transmits a reservation response to the job scheduler. The job scheduler acquires a certificate signed by the user from the end terminal and transmits the acquired certificate to the resource proxy. In response to the certificate of the user, the resource proxy makes a reservation of the identified resource according to the scheduled period.Type: GrantFiled: December 1, 2004Date of Patent: April 19, 2011Assignee: NEC CorporationInventor: Masahiro Kawato
