---+ High Performance Systems and Interconnects

Nowadays, the increasing development of network subsystems in cluster and high performance computing has shifted the main concern surrounding data transfer; the bottleneck of cluster communication no longer lies in the network architecture, but rather in the latency induced by the operating system. Recent years research has demonstrated that user-level networking can overcome traditional networking schemes (found in clusters) that demand high CPU usage and large memory consumption. High speed interconnects that utilize low-level message
passing system software allow userspace networking to minimize the use of host memory bandwidth and increase the speed of data transfer schemes. In order to achieve high speed user-level data exchange between cluster nodes, one has to account for different i/o architectures in systems software (such as modern network interfaces running custom firmware that drives data through shorter paths in the memory hierarchy subsystem).
