Arithmetic processing apparatus, control method, and recording medium

A control method executed by a processor included in an arithmetic processing apparatus, the method comprising:

• acquiring input data and output data in each of a plurality of operations using predetermined data for an information processing including the plurality of operations of a floating-point format to;
• extracting a specific operation represented by a complicated function including at least a transcendental function among the plurality of operations;
• obtaining an alternative function having a smaller computation amount than the complicated function in the extracted specific operation based on the input data;
• and
• substituting the specific operation in the information processing with the alternative function.

A non-transitory computer-readable recording medium storing a program that causes a processor included in an arithmetic processing apparatus to execute a process, the process comprising:

• acquiring input data and output data in each of a plurality of operations using predetermined data for an information processing including the plurality of operations of a floating-point format to;
• extracting a specific operation represented by a complicated function including at least a transcendental function among the plurality of operations;
• obtaining an alternative function having a smaller computation amount than the complicated function in the extracted specific operation based on the input data;
• and
• substituting the specific operation in the information processing with the alternative function.
