Abstract

The InfiniBand/sup TM/ Architecture (IBA) is envisioned to be the default communication fabric for future system area networks (SAN). However, the released IBA specification outlines only higher level functionalities, leaving it open for exploring various design alternatives. In this paper we investigate four co-related techniques to provide high and predictable performance in IBA. These are: (i) using the shortest path first (SPF) algorithm for deterministic packet routing; (ii) developing a multipath routing mechanism for minimizing congestion; (iii) developing a selective packet dropping scheme to handle deadlock and congestion; and (iv) providing multicasting support for customized applications. These designs are evaluated using an integrated workload on a versatile IBA simulation testbed. Simulation results indicate that the SPF routing, multipath routing, packet dropping, and multicasting schemes are quite effective in delivering high and assured performance in clusters. One of the major contributions of this research is the IBA simulation testbed, which is an essential tool to evaluate various design tradeoffs.

InfiniBand/sup TM/架构的性能增强技术

InfiniBand/sup TM/ Architecture (IBA)被设想为未来系统区域网络(SAN)的默认通信结构。然而，发布的IBA规范只概述了更高级别的功能，为探索各种设计替代方案留下了空间。在本文中，我们研究了四种相互关联的技术，以提供IBA的高和可预测的性能。它们是:(i)使用最短路径优先(SPF)算法进行确定性分组路由;(ii)发展多径路由机制，以尽量减少拥塞;(iii)制订选择性弃包方案，以处理死锁和拥塞;(iv)为定制应用程序提供多播支持。这些设计是在一个通用的IBA模拟测试平台上使用集成工作负载进行评估的。仿真结果表明，SPF路由、多径路由、丢包和组播等方案都能有效地在集群中提供高可靠的性能。本研究的主要贡献之一是IBA仿真试验台，它是评估各种设计权衡的重要工具。
