Computer-readable recording medium storing information processing program, information processing apparatus, and information processing method

An information processing apparatus configured to start hardware prefetching upon detecting an access to a consecutive area on a main storage device and to stop the hardware prefetching upon detecting an end of the access to the consecutive area, the information processing apparatus comprising:

• a processor, and
• a memory storing a program causing the processor to execute:
• analyzing a source program;
• specifying an array structure in a loop process as a hardware prefetching target;
• and
• generating, from the source program, a machine language program in which the array structure is changed so that a second access occurring next to a first access to the array structure refers to an area being consecutive from the area being referred to by the first access.

An information processing method comprising:

• analyzing a source program with respect to an information processing apparatus that starts hardware prefetching upon detecting an access to a consecutive area on a main storage device and stops the hardware prefetching upon detecting an end of the access to the consecutive area;
• specifying an array structure in a loop process as a hardware prefetching target;
• and
• generating, from the source program, a machine language program in which the array structure is changed so that a second access occurring next to a first access to the array structure refers to an area being consecutive from the area being referred to by the first access.
