In order to generate a source program or an object code which can be executed in parallel efficiency by detecting an independent operation of a large grain size from a program which can not be analyzed by the compiler, a parallelization supporting tool inputs a result of an output of the interprocedural analyzer,and the source program. A program of intermediate language is produced by the parse and the program of information of common and dummy argument variables is reflected into the program of intermediate language by the interprocedural variable information read processing. After a control flow analysis and a dataflow analysis have been carried out, dependency unknown variables are extracted and parallelizability conditions are produced. Based on the result of the produced conditions, questions and answers are made with the user or a condition statement is inserted into the source program to execute the program and a decision of parallelizability is made. A source program or a parallelized object program which has been corrected in accordance with a user's request is also produced.
