Title:

JADE Heterogeneous Multiprocessor Design & Simulation Environment

Abstract:

Heterogeneous multiprocessor/multicore/manycore systems are promising alternatives to traditional homogeneous multiprocessor systems, and they offer better tradeoffs among energy efficiency, performance, flexibility, scalability, and cost. However exploring their heterogeneities is not well supported by traditional simulators which rely on compliers and operating systems developed for homogenous multiprocessor systems. To overcome these issues, we developed and released a heterogeneous multiprocessor system design exploration and simulation environment called JADE (www.ece.ust.hk/~eexu/JADE.html). JADE supports statistical, recorded, and synthetic application models. It can model network-on-chips, inter-chip networks, and intra-rack networks using optical and electrical interconnects. JADE supports cache coherence. It can simulate low-power techniques such as clock gating, DVFS, and power gating with built-in power analysis.

Bio:

Jiang Xu received his Ph.D. degree from Princeton University. From 2001 to 2002, he worked at Bell Labs, NJ, as a Research Associate and discovered the First Generation Dilemma in platform-based SoC design methodologies. He was a Research Associate at NEC Laboratories America, NJ, from 2003 to 2005 and working on Network-on-Chip designs and implementations. He joined a startup company, Sandbridge Technologies, NY, from 2005 to 2007 and worked on the development and implementation of two generations of NoC-based ultra-low power Multiprocessor Systems-on-Chip for mobile platforms. Dr. Xu established Big Data System Lab, Xilinx-HKUST Joint Lab, and OPTICS Lab, at the Hong Kong University of Science and Technology. He currently serves as the Associate Editor for IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems, Associate Editor for IEEE Transactions on Very Large Scale Integration Systems, and Area Editor of NoC, SoC, and GPU for ACM Transactions on Embedded Computing Systems. He served on the steering committees, organizing committees, and technical program committees of many international conferences, including DAC, ICCAD, CASES, ICCD, CODES+ISSS, NOCS, RTCSA, HiPEAC, ASP-DAC, etc. Dr. Xu is an IEEE Distinguished Lecturer and was an ACM Distinguished Speaker. He authored and coauthored more than 90 book chapters and papers in peer-reviewed journals and international conferences. He and his students received Best Paper Award from IEEE Computer Society Annual Symposium on VLSI in 2009, and Best Poster Award from AMD Technical Forum and Exhibition in 2010. He coauthored a book titled Algorithms, Architecture and System-on-Chip Design for Wireless Applications (Cambridge University Press). His research areas include big data system, heterogeneous computing, optical interconnection network, power delivery and management, MPSoC, low-power embedded system, hardware/software codesign.
