Abstract
For the past years, architectures and programming models about distributed virtual shared-memory (DVSM) systems have been extensively studied. The DVSM needs communication between distributed processing nodes in order to maintain memory consistency, therefore the communication-related overhead determines the overall performance. Recently many advanced hardware-based interconnection technologies have been introduced, and one of them is the InfiniBand Architecture (IBA) which supports shared-memory programming semantics by means of remote direct-memory access (RDMA) and atomic operations. In this paper, we describe the implementation of our InfiniBand-based DVSM system, and evaluate its performance using SPEC OMP benchmarks. We show that our DVSM system to use full features of the IBA can improve the performance significantly over the IPoIB-based traditional system on the IBA, and furthermore the performance of one application on the IBA-based DVSM system is better than on the hardware-based shared-memory system.
