40 Gigabit Ethernet: Prototyping Transparent End-to-End Connectivity
The ever increasing demands of data intensive e-Science applications have pushed the limits of computer networks. With the launch of the new 40 Gigabit Ethernet (40GE) standard, 802.3ba, applications can go beyond the common 10 Gigabit/s per data stream barrier for both local area, and as demonstrated in the GLIF 2010 and Supercomputing 2010 demos, wide area setups. In this paper, the authors profile the performance of state-of-the-art server hardware combined with 40GE technology. They give an insight on the issues involved with ultra high performance network adapters and suggest optimization approaches.
