Description

A method, computer system and article of manufacture for optimizing a computer program, the method comprising the steps of executing an application program and profiling selected loops of the executing program. Characteristics of the profiled loops are then compared to corresponding predetermined threshold values and the results of the comparison are used to select an optimization to be applied to subsequent execution of the selected loops. In a preferred embodiment, the optimization is the selection of either a parallel version or a serial version of the loop. Further embodiments provide for the selection of the number of processors for parallel implemented loops and for the selection of an unroll factor in serially implemented loops.
