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 firmare that drives data through shorter paths in the memory hierarchy subsystem). |
