Cost/Performance Tradeoffs in Network Interconnects for Clusters of Commodity PCs

Cost/Performance Tradeoffs in Network Interconnects for Clusters of Commodity PCs
The definition of a commodity component is quite obvious when it comes to the PC as a basic compute engine and building block for clusters of PCs. Looking at the options for a more or less performant interconnect between those compute nodes it is much less obvious which interconnect still qualifies as commodity and which not. We are trying to answer this question based on an in-depth analysis of a few common more or less expensive interconnects on the market. Our measurements and observations are based on the experience of architecting, procuring and installing Xibalba, a 128 node - 192 processor versatile cluster for a variety of research applications in the CS department of ETH Zurich. We define our unique way to measure the performance of an interconnect and use our performance characterization to find the best cost performance point for networks in PC clusters. Since our work is tied to the purchase of a machine at fair market value we can also reliably comment on cost perform...
