 Active Access: A Mechanism for High-Performance Distributed Data-Centric Computations

(In Proceedings of the 29th International Conference on Supercomputing (ICS'15), presented in Newport Beach, CA, USA, pages 155--164, ACM, ISBN: 978-1-4503-3559-1, Jun. 2015)

Abstract

Remote memory access (RMA) is an emerging programming model and a mechanism that uses RDMA-capable hardware to reduce data transfer latencies. Another mechanism for improving performance in distributed environments is active messaging (AM) that enhances message passing (MP). In this paper we present Active Access (AA), a mechanism and a programming model that combines AM semantics with RMA to enable high-performance distributed data-centric computations. In AA, the user speci es handlers that are triggered when incoming puts and gets reference designated addresses. AA outperforms optimized AM and traditional RMA designs, accelerates various codes such as distributed hashtables or logging schemes, and enables new protocols such as incremental checkpointing for RMA. AA facilitates more ective utilization of HPC centers and datacenters.
