A bandwidth challenge at Super Computing (SC) Conference: Large-scale data transfer using 10Gbps network

Results of bandwidth challenge contest at Super Computing (SC) 2007 by NICT are discussed. The target of this contest is to make full use of 10 Gbps network for any scientific applications. We, NICT team, attempted to transfer large-scale numerical data at NICT (in Japan) to SC 2007 venue in Reno, USA. We optimized our data transfer system for the real-time computer simulation data, and finally obtained through-put from Japan to USA as high as 4 Gbps.
