20080313405 | Coherency maintaining device and coherency maintaining method - A second-level cache device stores part of registration information of data for a first-level cache device in a second-level cache-tag unit in association with registration information in a second-level-cache data unit, and stores the registration information of data for the first-level cache device in a first-level cache-tag copying unit. A coherency maintaining processor maintains coherency between the first-level cache device and the second-level cache device based on the information stored in the second-level cache-tag unit and the first-level cache-tag copying unit. | 12-18-2008 |
20120047387 | Cache control device and cache control method - A cache control device includes, in a secondary cache data unit, a clean area that stores only information that is the same information as that stored in a main storage. Then, the cache control device monitors information on electrical power consumption of the cache control device, determines whether the information on the electrical power consumption is equal to or greater than a predetermined threshold, monitors an activity ratio of a cache memory, and determines whether the activity ratio is equal to or less than a predetermined threshold. Subsequently, if the cache control device determines that the information on the electrical power consumption is equal to or greater than the predetermined threshold or determines that the activity ratio of the secondary cache memory is equal to or less than the predetermined threshold, the cache control device performs control such that the clean area in the secondary cache data unit is degenerated. | 02-23-2012 |
20140208030 | INFORMATION PROCESSING APPARATUS AND CONTROL METHOD OF INFORMATION PROCESSING APPARATUS - An information processing apparatus including a plurality of mutually connected system boards, wherein each of the system boards includes: a plurality of processors; and a plurality of memories each of which stores data and directory information corresponding to the data, and corresponds to any one of the processors, and wherein each of the plurality of processors, upon receiving a read request for data stored in a memory corresponding to the own processor from another processor, performs an exclusive logical sum operation on identification information included in the read request and identifying the another processor and a check bit included in the directory information and identifying a processor which holds target data of the read request, increments a count value included in the directory information and indicating the number of processors which hold the target data, and sets presence information included in the directory information and indicating a system board which includes the another processor. | 07-24-2014 |
20140331013 | ARITHMETIC PROCESSING APPARATUS AND CONTROL METHOD OF ARITHMETIC PROCESSING APPARATUS - An arithmetic processing apparatus according to one embodiment of the present invention includes: a plurality of arithmetic processing units configured to perform arithmetic operations to output access requests; a cache memory to retain data undergoing the arithmetic processes of the arithmetic processing units in cache blocks; a retaining unit configured to retain a control target address specifying a control target cache block and control target identifying information specifying an arithmetic processing unit of a control target access requester; and a control unit configured to control an access request for the cache block specified by the control target address and the control target identifying information on the basis of an access target address contained in an access request issued by any one of the arithmetic processing units and requester identifying information specifying the arithmetic processing unit having issued the access request. | 11-06-2014 |
