摘要

当一个同步多线程(SMT)核心执行来自同质并行应用程序的两个线程时，线程融合是一种有效的降低功耗的方法。同一个静态指令的两个动态实例，每个来自不同的线程，被合并(融合)成一个指令，消耗前端管道阶段一半的资源。当融合指令被执行时，它被克隆并在全带宽下执行。我们的模拟结果表明，平均能耗降低10%，对性能的影响小于1%。

Thread fusion

This work proposes Thread Fusion as an effective way of reducing power consumption when a Simultaneous Multi-Threaded (SMT) core is executing two threads from a homogeneous parallel application. Two dynamic instances of the same static instruction, each from a different thread are merged (fused) into a single instruction, consuming half of the resources of front-end pipeline stages. When the fused instruction is executed, it is cloned and it proceeds at full bandwidth. Our simulation results show average energy reduction of 10% with less than 1% impact on performance.
