Overview:
In this paper the authors investigate the necessity of a high speed interconnect for Linux based clusters and the performance differences between Myrinet and Ethernet connected networks. The authors benchmark applications and network performance in a dedicated environment with varying workloads and processing elements. The authors show that for certain workloads, a high speed interconnect is not required. The paper also examines the increased complexity of introducing high-speed switch fabrics, the importance of their underlying device drivers, and their usefulness with real applications. Finally, the authors make recommendations as to which network to use given a certain workload and available computation nodes.
