PROBLEM TO BE SOLVED: To provide a technique for preparing complicated plural parallel programs with excellent reliability and efficiency. SOLUTION: A preparing means 3 prepares the scenario of execution from a first parallel program 2. An analyzing means 12 extracts a dependent relation from the first parallel program 2. A decomposing means 5 hierarchically decomposes the scenario judged to be correct into blocks in which a loop is not included. A paralleling mean 7 parallels the scenario by assigning the scenario to plural processes by using the block as a unit. An integrating means 8 integrates the assigned scenario for each process. A generating means 10 generates a second parallel program 11 from the integrated scenario of each process. Even the parallel program whose structure is complicate is decomposed into blocks and processed so as to be developed as easy as sequential programming.
