Resum
We provide an analysis of thread-management techniques that increase performance or reduce energy in multicore and Simultaneous Multithreaded (SMT) cores. Thread delaying reduces energy consumption by running the core containing the critical thread at maximum frequency while scaling down the frequency and voltage of the cores containing noncritical threads. In this article, we provide an insightful breakdown of thread delaying on a simulated multi-core microprocessor. Thread balancing improves o...
