Abstract
In a method of generating an object program for a multiprocessor system from a source program including a loop, there is detected a variable in the loop. For the detected variable, first codes providing a one-dimensional work array are added to the source program. The work array has elements whose the number is predetermined according to a maximum number of parallel processes to be generated for the loop and is shared among the parallel processes. It is determined whether or not the variable is used outside the loop. When it is determined that the variable is not used at any position outside the loop, the source program with the first codes added is compiled to produce the object program, thereby executing the loop in a parallel fashion by the parallel processes using the elements of the work array as a local variable associated with the variable.
