Inferential queueing and speculative push for reducing critical communication latencies

Abstract

Communication latencies within critical sections constitute a major bottleneck in some classes of emerging parallel workloads. In this paper, we argue for the use of Inferentially Queued Locks (IQLs) [31], not just for efficient synchronization but also for reducing communication latencies, and we propose a novel mechanism, Speculative Push (SP), aimed at… (More)
