论文摘要
Smartnics最近已成为加速分布式系统的吸引人的设备。但是，尚未对智能机构进行全面的特征，现有设计通常只利用单个通信路径来卸载。本文从通讯路线的角度出发了对代表分开的智能智能官员，特别是蓝场合2的首次整体研究。我们的实验研究系统地探讨了客户，车载SOC和主机之间交流的关键性能特征，并为设计师提供了有见地的发现和建议。此外，我们建议同时使用智能的多个通信路径，并提出开拓性指南，以揭示各种分布式系统的新优化机会。为了证明我们方法的有效性，我们对基于智能的分布式文件系统（LineF）和基于RDMA的分类密钥值商店（DRTM-KV）进行了案例研究。我们的实验结果表明，LineF和DRTM-KV分别提高了30％和25％。
SmartNICs have recently emerged as an appealing device for accelerating distributed systems. However, there has not been a comprehensive characterization of SmartNICs, and existing designs typically only leverage a single communication path for workload offloading. This paper presents the first holistic study of a representative off-path SmartNIC, specifically the Bluefield-2, from a communication-path perspective. Our experimental study systematically explores the key performance characteristics of communication among the client, on-board SoC, and host, and offers insightful findings and advice for designers. Moreover, we propose the concurrent use of multiple communication paths of a SmartNIC and present a pioneering guideline to expose new optimization opportunities for various distributed systems. To demonstrate the effectiveness of our approach, we conducted case studies on a SmartNIC-based distributed file system (LineFS) and an RDMA-based disaggregated key-value store (DrTM-KV). Our experimental results show improvements of up to 30% and 25% for LineFS and DrTM-KV, respectively.
