1 The LAC/UIC experiences through JGN2/APAN during SC04 Katsushi Kouyama and Kazumi Kumazoe Kitakyushu JGN Research Center / NiCT Robert L. Grossman, Yunhong Gu, Xinwei Hong, Michal Sabala, and David Handley University of Illinois of Chicago

2 Outline Introduction of NCDM / LAC Introduction of UDT Demos of UDT in SC2004 Request and Comment for JGN2 / APAN on SC2004

3 Introduction to NCDM/LAC NCDM: National Center for Data Mining –UIC: University of Illinois of Chicago –Standard development, Data Mining and Predictive modeling –organized into laboratories LAC: Laboratory for Advanced Computing LAC/UIC activities –data intensive computing –distributed computing –high performance computing and networking : UDT

4 TCP and AIMD TCP has been very successful in the Internet –AIMD (Additive Increase Multiplicative Decrease) Fair: max-min fairness Stable: globally asynchronously stable But, inefficient and not scalable –over high-speed wide area network RTT bias

5 UDT – UDP-based Data Transfer Protocol Application level transport protocol built above UDP Reliable data delivery Congestion control mechanisms General transport API; not a (file transfer) tool. Open source

6 UDT - Objectives Goals –Easy to install and use –Efficient for bulk data transfer –Fair –Friendly to TCP Non-goals –TCP replacement –Messaging service

7 UDT Architecture DATA ACK ACK2 NAK Sender Receiver Sender Receiver Pkt. Scheduling Timer ACK Timer NAK Timer Retransmission Timer Rate Control Timer Sender DATA

8 Demos of UDT in SC2004 Tokyo SC04 StarLight JGN2/APANAbileneSURFnet Tokyo Amsterdam Pittsburgh (SC04) Amsterdam 10Gbps Network Configuration

9 Demos of UDT in SC2004 Tokyo SC04 –Disk-to-Disk Transmission (1.5 Terabytes) –Sloan Digital Sky Survey (SDSS) data –Two Pair of machines SC Amsterdam/Tokyo –Memory-to-Memory Transmission –Pseudo data –Parallel flows

10 Results of Demos in SC Gbps real data file transfer between Pittsburgh and Tokyo. 16Gbps memory data transfer in and out Pittsburgh from/to Tokyo and Amsterdam. Winner of one of the bandwidth challenge awards –Best replacement of FedEx / UDP fairness award JGN2 Link

11 Request and Comment for usage of network on SC2004 Introduction of the Reservation System via web (not via ) We appreciate for the strong support and cooperation during SC2004 and our on- going collaboration work.
