Enhancing TCP Performance for Dedicated Clusters and Grids
Category: Data Management, Networking and Communications
Overview TCP congestion control methods seriously and unnecessarily harm performance of network transmissions when used in dedicated clusters and grids. This paper presents a simple method in which congestion control can be disabled under appropriate circumstances while still addressing fairness issues and avoiding congestion collapse. The paper discusses a Linux-based implementation of this "Rude TCP" and demonstrates the performance benefits this change provides over one and ten gigabit Ethernet links in Linux - showing a factor of 20 improvement in some cases.
