The highly efficient zero copy software system that was developed at the institute of computer systems circumvents data copies while communicating over Gigabit Ethernet. This allows very high bandwidths. This project implements some techniques to optimize the latency.


The goal of this work was to propose and implement an all-to-all barrier synchronization directely on driver level. To test the implementation which resulted in barrier latencies of 40 us for 16 nodes an all-to-all-communication test application was implemented.
