Unlocking Energy

Rachid Guerraoui, Babak Falsafi, Javier Picorel Obando, Vasileios Trigonakis

Locks are a natural place for improving the energy efficiency of software systems. First, concurrent systems are mainstream and when their threads synchronize, they typically do it with locks. Second, locks are well-defined abstractions, hence changing the ...
