SUMMARY:Hardware-Supported Remote Persistence for Distributed Persistent M

DESCRIPTION:Paper\n\nHardware-Supported Remote Persistence for Distributed
  Persistent Memory\n\nDuan, Lu, Liu, Liao, Jin...\n\nThe advent of Persist
 ent Memory (PM) necessitates an evolution of Remote Direct Memory Access (
 RDMA) technologies for supporting  remote data persistence. Previous softw
 are-based solutions require remote CPU intervention and postpone the visib
 ility of remote persistence. In this paper, we design several hardware-sup
 ported RDMA primitives to flush data from the volatile cache of RDMA Netwo
 rk Interface Cards (RNICs) to the PM. We also propose durable RPCs based o
 n the proposed RDMA Flush primitives to support remote data persistence an
 d fast failure recovery. We emulate the performance of RDMA Flush primitiv
 es through other RDMA primitives, and compare our proposals with several s
 tate-of-the-art RPCs in a real testbed equipped with PM and InfiniBand net
 works. Experimental results show that our proposals can improve the throug
 hput of RPCs by up to 90%, and reduce the 99th percentile latency by up to
  49%. The experimental studies also provide instructive guidelines for des
 igning RDMA-based distributed PM systems.\n\nTag: Reproducibility Badge, M
