Characterizing the dynamic behavior of a program is essential for optimizing the program on a given system. Once the program's repetitive execution phases (and their boundaries) have been correctly identified, various phase-aware optimizations can be applied. Multithreaded workloads exhibit dynamic behavior that is further affected by the sharing of data and platform resources. As computer systems and workloads become denser and more parallel, this effect will intensify the dynamicity of the executed workload.
