Software Distributed Shared Memory over Virtual Interface Architecture: Implementation and Performance
Muralidharan Rangarajan and Liviu Iftode, Rutgers University
Abstract
In this paper, we describe an implementation of software Distributed Shared Memory (DSM) over Virtual Interface
Architecture (VIA) for a Linux-based cluster of PCs and evaluate its performance. VIA is a user-level memory-mapped
communication model that provides zero-copy communication and low-overhead by excluding the operating system
kernel from the communication path. To our best knowledge, our implementation is the first software DSM protocol on
VIA.
The DSM protocol we have implemented on VIA is Home-based Lazy Release Consistency (HLRC) that previous
studies have shown to exhibit good scalability by reducing the number of messages and memory overhead compared to
the homeless counterpart. The experimental results obtained on seven Splash-2 applications show that VIA can be
successfully used to support software shared memory on clusters of PCs. The paper is accompanied by a source-code
distribution of the software DSM protocol for Linux/VIA clusters.
