Abstract: Having a high-bandwidth and low-latency interconnect usually makes the main difference between computerswhich are connected via a regular low-bandwidth, high-latency network and a so-called supercomputer or HPCsystem. Different interconnection types are available, either from individual vendors for their specific HPC setup or inthe form of a separate product, to be used in a variety of different systems. For the user of such a system, theinterconnect is often seen as a black box. This guide will give an overview of the most common types of interconnects in the current generation of HPCsystems. It will introduce the key features of each interconnect type and the most common network topologies.The selected interconnect type within the current generation of PRACE Tier-0 systems will be listed and the finalsection will give some hints concerning network benchmarking.
