Abstract: A compiler program causes a computer to execute optimization processing for an optimization target program. The optimization target program includes a loop including a vector store instruction and a vector load instruction for an array variable. The optimization processing includes (1) unrolling the vector store instruction and the vector load instruction in the loop by an unrolling number of times to generate a plurality of unrolled vector store instructions and a plurality of unrolled vector load instructions, and (2) scheduling to move an unrolled vector load instruction among the plurality of unrolled vector load instructions, which is located after a first unrolled vector store instruction that is located at first among the plurality of unrolled vector load instructions, before the first unrolled vector store instruction.

Abstract: An apparatus stores a program including a description of loop processing of iterating a plurality of instructions, and rearranges an execution sequence of the plurality of instructions in the program such that the loop processing is pipelined by software pipeline. The apparatus inserts an instruction to use a register for single instruction multiple data (SIMD) extension instruction, into the description of the loop processing in the program.

Abstract: An operation processing apparatus including a processor, and memory configured to store a program to instruct the processor to perform: acquiring a part corresponding to a predetermined area of an original program; generating a value of data used in the predetermined area immediately before the part corresponding to the predetermined area is executed and information of overlapping of cache index for the data in the predetermined area in a case in which cache memory used for executing the original program operates as one-way cache memory; and executing the part corresponding to the predetermined area using the generated value immediately before the part corresponding to the predetermined area is executed and the information of the overlapping of the cache index.
