Polyhedral model could deal with the many situations, including loops, branches in loops,function calls in loops and so on and could save information as model parameters which could not identify. With the user defined architecture files, this paper built a parameterized performance model, so that provided a way for modeling performance of HPC applications. It produced the execution counts of different kinds of instructions by analyzing the source codes and binary codes of the target applications. It avoided the computing resources and time cost and had high applicability,flexibility and accuracy. Meanwhile, it could predict other data related to performance based on the model.
