Summary:PURPOSE:To automatically specify a DO loop to be an object to be vectorized by generating a vectorized numeral calculation program added with a vectorized instruction line or a scalar instruction line according to detected subscript dependency. CONSTITUTION:A subscript dependency information output program generation calculating part 1 makes a numeral calculation program added with a subscript dependency detection instruction line execute a subscript dependency information output statement by adding it, and a subscript dependency detecting part 2 evaluates result data 13 outputted by the execution of the subscript dependency information output statement, and detects the subscript dependency. Then, a subscript dependency information added program generating part 3 generates the vectorized numeral calculation program 14 added with the vectorized instruction line or the scalar instruction line according to the detected subscript dependency. Thus, the generated vectorized numeral calculation program 14 is translated into an object program containing a corresponding code by a widely-known compiler, and is converted into a form executable by an electric computer, and is executed.
