GPUs spend significant time on synchronization stalls. Such stalls provide ample opportunity to save leakage energy in GPU structures left idle during such periods. In this paper we focus on the register file structure of NVIDIA GPUs and introduce sync-aware low leakage solutions to reduce power. Accordingly, we show that applying the power gating technique to the register file during synchronization stalls can improve power efficiency without considerable performance loss. To this end, we equip the register file with two leakage power saving modes with different levels of power saving and wakeup latencies.
