Abstract: A method for selecting a steel material for a rolling component to be used in an environment in which hydrogen enters steel. The method includes determining a maximum contact surface pressure Pmax acting on a rolling surface of the rolling component, and using, as a material for the rolling component, a material whose inclusion has a radius not greater than a radius d determined by the following formula (1) and not less than 1.0 ?m, d=64729(Pmax/4)?1.441 ??(1).

Abstract: An information processing apparatus includes a memory, and a processor coupled to the memory and configured to count first number indicating storing a plurality of arrays of data to each of cash lines, the data being accessed in accordance with execution of a program, and count second number indicating cache thrashing to the cache lines when the first number exceeds number of ways of cache.

Abstract: A data processing method executed by a processor included in an information processing device, the data processing method includes reserving a storage area of a memory when a reservation request is detected; acquiring a number of cache misses indicating that desired data is not capable of being read from a storage area to be accessed, the cache misses having occurred in response to a request for access to the storage area; and setting a new storage area so as to shift the new storage area from the reserved storage area when it is determined that the acquired number is larger than or equal to a given value.

Abstract: A rolling component material of the present invention is a steel material for a rolling component to be used in an environment in which hydrogen enters steel, and is a material used for a rolling component of a rolling bearing, for example, a bearing ring. In the rolling component material, a non-metallic inclusion of the steel material has a radius not greater than a radius d determined by the following formula (1) and not less than 1.0 ?m, where Pmax is defined as a maximum contact surface pressure acting on a rolling surface of the rolling component, d=64729(Pmax/4)?1.441??(1).

Abstract: In a distributed-memory multiprocessor system in which a plurality of processors have their respective memories, some of the processors are placed in redundant execution of writing into a virtual storage space. At redundant execution, each processor makes a determination of whether or not it is to perform the writing. As a consequence, only a single processor is allowed to write data into the virtual storage space, which solves the data transfer overhead problem. If a processor that has a memory with an area to be written into performs the writing, then the speed of processing will be further increased.

Abstract: A parallel computer of a distributed storage type, which can omit an overhead time of a processing apparatus required for an address computation, is provided with an array address converting apparatus for generating a PE number of a PE retaining an array element that is an object of an access and an address on storage apparatus of the array element within the PE in each PE. Upon an access to an array element of array data, the processing apparatus activates the array address converting apparatus, a communicating apparatus gives an address on storage apparatus generated by the array address converting apparatus to a PE having a PE number generated by the array address converting apparatus to transmit access demand information for the array element. This parallel computer of a distributed storage type is applicable to a computer system for processing enormous data at a high speed such as numerical calculation, image processing or the like.
