Although most current multicore processors are homogeneous, microarchitects are now proposing heterogeneous core implementations, including systems in which heterogeneity is introduced at runtime. This paper shows that operating system schedulers must consider dynamic heterogeneity or suffer significant power-efficiency and performance losses. all current and future high-performance processor chips are multicore processors, also known as Chip MultiProcessors (CMPs). These multicore processors include the Cell Broadband Engine, Intel's Core Duo and Quad-Core Xeon, AMD's Dual-Core Opteron, Sun Microsystems' Niagara, and IBM's Power5.
