20140053012 | SYSTEM AND DETECTION MODE - A system includes a CPU; a sensor that detects power of the CPU; a cache memory state monitoring circuit that monitors a state of a cache memory; and a detection circuit that based on a sensor signal from the sensor and a state signal from the cache memory state monitoring circuit, detects a spin state of a program executed by the CPU. | 02-20-2014 |
20140053162 | THREAD PROCESSING METHOD AND THREAD PROCESSING SYSTEM - A thread processing method is executed by a specific apparatus included among a plurality of apparatuses, and includes assigning one thread among a plurality of threads to the apparatuses, respectively; acquiring first time information that indicates a time at which the specific apparatus receives an execution result of a corresponding thread from each of the apparatuses; and setting a priority level of an access right to access shared memory that is shared by the apparatuses and the specific apparatus, the setting being based on the first time information and second time information that indicates a time at which reception of execution results of the threads from the apparatuses ends. | 02-20-2014 |
20140053163 | THREAD PROCESSING METHOD AND THREAD PROCESSING SYSTEM - A thread processing method that is executed by a multi-core processor, includes supplying a command to execute a first thread to a first processor; judging a dependence relationship between the first thread and a second thread to be executed by a second processor; comparing a first threshold and a frequency of access of any one among shared memory and shared cache memory by the first thread; and changing a phase of a first operation clock of the first processor when the access frequency is greater than the first threshold and upon judging that no dependence relationship exists. | 02-20-2014 |
20140082041 | DATA PROCESSING METHOD - A data processing method is executed by a processor, and includes detecting an addition request to add a first device to a first group that includes a plurality of devices; registering the first device into a main group in which devices of the first group are registered, the first device being registered when the first device does not belong to a second group that is different from the first group; registering the first device into a subgroup, when the first device belongs to the second group; and performing by the devices registered in the main group, distributed processing that includes a plurality of tasks. | 03-20-2014 |
20140082637 | DATA PROCESSING METHOD AND DATA PROCESSING SYSTEM - A data processing method executed by a first data processing apparatus and includes acquiring process information concerning a first process, in response to a process request for the first process; setting a first process flag included in the process information concerning the first process to indicate “true”; setting a first end flag of the process information concerning the first process to indicate “true” after executing the first process; acquiring process information concerning a second process that is to be executed before a third process that is to be executed subsequent the first process; and determining a process to be executed, based on a second process flag and a second end flag included in the process information concerning the second process. | 03-20-2014 |
20140282588 | SYSTEM AND SCHEDULING METHOD - A system includes a CPU; an accelerator; a comparing unit that compares a first value that is based on a first processing time period elapsing until the CPU completes a first process and a second processing time period elapsing until the accelerator completes the first process, and a second value that is based on a state of use of a battery driving the CPU and the accelerator; and a selecting unit that selects any one among the CPU and the accelerator, based on a result of comparison by the comparing unit. | 09-18-2014 |
20150081942 | MULTI-CORE PROCESSOR SYSTEM, COMPUTER PRODUCT, AND CONTROL METHOD - A multi-core processor system includes a given configured to queue an interrupt process of a software interrupt request to the given core, and execute queued processes in the order of queuing at the given core; execute preferentially an interrupt process of a hardware interrupt request to the given core over a process under execution at the given core; determine whether the software interrupt request is a specific software interrupt request; and perform control to preferentially execute the interrupt process without queuing, upon determining that the software interrupt request is the specific software interrupt request. | 03-19-2015 |

20100329409 | DRAIN SUMP OF NUCLEAR REACTOR CONTAINMENT VESSEL - A drain sump of a reactor containment vessel having a containment vessel floor down below a reactor pressure vessel, and includes a heat-proof sump cover and two or more drain flow paths. The drain sump is arranged inside the containment vessel floor. The heat-proof sump cover has a thickness, and covers an upper part of the drain sump. The thickness allows a top surface of the sump cover to lie in the same surface as a top surface of the containment vessel floor. The drain flow paths pass through the sump cover in a thickness direction to flow water therethrough and solidify a molten corium therein. The molten corium is produced in the unlikely event of a severe accident. | 12-30-2010 |
