Abstract: This paper introduces the methodology used in analyzing and tuning ORC (open research compiler), an open resource compiler based on IA64 architecture. It consists of a series of tools, methods and some experiences. Some successful stories and real performance trend can prove that it is a practical and effective methodology and it can also be used in the performance analysing and tuning of other applications.
