Abstract: The potential of parallel discrete-event simulation has been demonstrated in running large-scale network models. However, the utility of conducting high-fidelity extreme-scale network simulations on high-end computing platforms is currently limited due to many issues, including non-scalable simulation system design, unrealistic network models, complex and inflexible experiment workflow. Supporting network simulation at scale requires major rethinking of simulation system design to comprehensively address the critical problems regarding performance, accuracy and controllability. In this talk, I will present an overview of our work at investigating techniques supporting large-scale network experimentation. I will provide an account of the current state of our parallel simulator derived from the Scalable Simulation Framework (SSF) and its applications in real-time immersive network simulation. In particular, I will focus on the PRIME and PrimoGENI projects--the two related projects aiming at providing a self-sustained large-scale virtual network environment for researchers to prototype, evaluate, and analyze distributed applications and network services. In addition, I will discuss our ongoing work in supporting high-performance network modeling, simulation and emulation. Short Biography: Jason Liu is currently an assistant professor at Florida International University. He received a B.A. degree in Computer Science from Beijing Polytechnic University in China in 1993, an M.S. in Computer Science from College of William and Mary in 2000, and a Ph.D. in Computer Science from Dartmouth College in 2003. His research interests include parallel discrete-event simulation, high-performance modeling and simulation of communication networks and computer systems. His current research focuses on applying real-time computation techniques for adaptive network simulation models, designing and building scalable emulation infrastructure for large-scale network simulations. Dr. Liu currently serves as a steering committee member for PADS, an associate editor for the SIMULATIONS journal, and the general chair for MASCOTS'10 and SIMUTools'11. Previously, he served as a program chair for SIMUTools'10 and PADS'08. He is a recipient of an NSF CAREER Award in 2006.
