具有大/高性能和小/低功耗内核的异构多核处理器已被提出作为替代设计，以提高传统同构多核的能效。我们提出了异构处理器内核中线程按比例共享调度的案例，旨在提高综合能源效率和性能。我们的线程调度算法lucky是基于彩票调度的，并在用户级别使用Linux性能监控和线程到核心亲和力功能来实现。我们的初步结果表明，与最先进的异构感知调度技术相比，幸运调度可以提供更好的性能和节能效果。
Heterogeneous multi-core processors with big/high-performance and small/low-power cores have been proposed as an alternative design to improve energy efficiency over traditional homogeneous multi-cores. We make the case for proportional-share scheduling of threads in heterogeneous processor cores aimed at improving combined energy efficiency and performance. Our thread scheduling algorithm, lucky, is based on lottery scheduling and has been implemented using Linux performance monitoring and thread-to-core affinity capabilities at user-level. Our preliminary results show that lucky scheduling can provide better performance and energy savings over state-of-the-art heterogeneous-aware scheduling techniques.
