An apparatus causes a management unit included in an arithmetic processing unit to manage, where an executable task is included in a queue, execution of the task. The apparatus causes a standby unit included in the arithmetic processing unit to execute, when the executable task is not included in the queue, a decision process for deciding, by polling, whether information from another apparatus different from the apparatus is received by a communication controller until the executable task is included in the queue.

Information processing apparatus, and information processing method

An information processing apparatus includes a memory; and a processor coupled to the memory and the processor configured to poll and monitor a plurality of monitoring targets, wherein the number of times of monitoring a first monitoring target is greater than the number of times of monitoring a second monitoring target.

Image processing apparatus, notification monitoring program, and notification monitoring method

A system includes circuitry configured to execute a first thread of a plurality of threads, measure an execution time period during which the circuitry executes the first thread without executing other threads of the plurality of threads, determine whether the measured execution time period exceeds a threshold value, specify first address information of a first instruction which is included in the first thread when it is determined that the measured execution time period exceeds the threshold value, the first instruction being an instruction that is scheduled to be executed, exchange the first instruction stored in an address region specified by the first address information with a second instruction instructing the circuitry to switch from executing the first thread to executing a second thread of the plurality of threads, and switch from executing the first thread to the executing the second thread by executing the second instruction.

System and method of executing a plurality of threads using thread switching on execution time-out using instruction re-write

An information processing apparatus includes: a memory configured to store an information processing program; and a plurality of processor cores configured to acquire and execute a task from a storage region which is provided for each of the processor cores and including a first processor core configured to execute the information processing program, wherein the first processor core: performs, in work steal in which a task stored in a storage region of the first processor core is acquired by a second processor core, a writing process for an abort region, which is provided corresponding to the task, for detecting access contention by the first processor core and the second processor core using a transactional memory function; and performs a reading process for the abort region when the task is to be acquired from the storage region.

Information processing apparatus, information processing method, and non-transitory computer-readable recording medium recording information processing program

An information processing apparatus includes: a memory configured to store a first code; and a processor configured to compile a source file to generate the first code, wherein the processor: generates a second code, which is executable by the processor, based on a result of analysis of the source program; and divides the second code into blocks of a size equal to or smaller than a given size including a reservation region to generate the first code.

Information processing apparatus, compile method and non-transitory recording medium storing compile program

An information processing apparatus includes a storage device and a processor that runs a virtual machine. The processor detects a waiting process that is ready for execution on the virtual machine, and writes process information about the detected waiting process in a storage area of the storage device, which is accessible area to management software managing the virtual machine.
