| | | 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)
AbstractRemote 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.
