Talk Title: Dynamic Dataflows & Resilient Execution on Clouds
Series: EE598 Seminar Course
Abstract: The emergence of ââ¬ÅBig Dataââ¬Â, due to improvements in scientific processes, deployment of pervasive sensors, and connected devices, coupled with improvements in communication technologies as well as storage and processing capabilities, has led to the need for development of data-intensive applications and application frameworks to analyze this huge collection of stored and continuous streams of Data. In this talk, we discuss the notion of Continuous Dataflows, as an extension to traditional workflows, for processing continuous data streams. In addition, we introduce the concept of Dynamic Dataflows to allow for both domain-driven and infrastructure-driven changes to the application at runtime. In this context, we discuss several challenges due to the dynamic nature of the application as well as the underlying Cloud infrastructure and present several opportunities and preliminary solutions to address those.
Biography: Alok Kumbhare is a PhD student working with Prof. Viktor K. Prasanna and Prof. Yogesh Simmhan in the Department of Computer Science at the University of Southern California, Los Angeles. His research focuses on distributed data and computing platforms, especially on the Cloud computing infrastructure. His current research interests include dynamic dataflow programming abstractions and their resilient execution on the dynamic infrastructure provided by the Cloud. In addition, he is working on a distributed Graph oriented file system and to leverage the dynamic dataflows for efficient execution of graph algorithms on extremely large data sets. He earned his BS degree in Computer Science and Engineering from Indian Institute of technology Guwahati in 2008.

Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Gavin Brennen, Macquarie University, Sydney
Talk Title: Excursions Through Flatland: Braiding Interactions of Anyons
Abstract: In systems with physics constrained to two dimensions, point like particles named anyons can occur which have more general exchange statistics than bosons or fermions. While these particles emerge as quasiparticle excitions from strongly correlated ``vacuum" states, they are long- lived and robust to perturbations. I will describe the transport properties of anyons in the presence of ordered and random topological environments. Using both a discrete time quantum walk model and a continuous time Hubbard model we find very distinct behaviours for Abelian and non-Abelian anyons which could be observed in experiment.
Biography: Gavin Brennen grew up in Alaska and did his studies at the U. of Alaska and U. of New Mexico receiving his PhD in theoretical physics from UNM in 2001. Afterward he worked as a research fellow at U. Maryland/NIST Gaithersburg, MD and as senior scientist at the Institute for Quantum Optics and Quantum Information, Innsbruck Austria. In 2007 he was appointed Assoc. Prof. at Macquarie University, Sydney where he and his group work on quantum information theory, coherent control of atomic/molecular/optical systems, and topological phases.

Speaker: Dr. Gerhard Sollner, Raytheon Company
Talk Title: Aging Treatments for CMOS Analog and Digital Circuits
Abstract: One beauty of Complementary Metal-oxide-Silicon (CMOS) transistors is that the carriers travel between source and drain in a nearly atomically smooth channel in the semiconductor adjacent to the oxide gate insulator. However, as device dimensions shrink, electric fields increase, carriers travel at higher velocities, and any imperfections in the channel-oxide interface become increasingly important.
CMOS transistors age when high-speed carriers in the channel break chemical bonds and dislodge atoms at the oxide-semiconductor interface. These uncompensated bonds are charged. They change the gate potential necessary to attract charges to the channel, that is, they change the threshold voltage. In addition, they act as scattering centers for carriers in the channel. These scattering centers reduce carrier mobility, which in turn reduces several parameters important to circuit performance such as gain and the maximum frequency of operation.
In this talk we will look carefully at the two most important physical processes of CMOS aging. It turns out that one is most important for digital circuits, the other is most important for analog circuits. Then, after a brief introduction to how aging processes are accelerated (so that you don’t have to measure for 10 years to predict a 10-year lifetime), we will show expressions from the literature that predict how these aging processes depend on temperature , electric fields, and time, for any CMOS device technology. Then some of our recent measurements on 65-nm digital devices will be described, along with their agreement with the literature.
The ultimate goal of this work is to develop anti-aging techniques, i.e. healing for CMOS circuits that undergo aging. To this end we designed several circuits, both analog and digital, in 45-nm CMOS. These all include internal circuits that measure the effects of aging and other circuits that adjust transistor biases to cure the aging and return the circuit to the performance level for which it was designed. To tie all this together, we will describe an algorithm that has demonstrated excellent results when finding the optimum bias levels in multi-dimensional nonlinear cases such as these.
The bottom line: we will show that aging effects can seriously degrade circuit performance. The cure is to either over-design the circuit, which reduces performance, or to apply anti-aging techniques, which result in compact, efficient circuits with high performance.
Biography: Dr. Sollner joined the Advanced Technology group at Raytheon Company in November 2009 where he now manages several programs. Before his current position Gerry founded and was CEO of a company, Kenet Inc, which successfully developed families of very-low-power analog-to-digital converters based on technology invented in his group at MIT Lincoln Laboratory. Kenet was acquired by Intersil Corporation. Prior to starting Kenet, Gerry spent 20 years at Lincoln Laboratory, leading the Analog Device Technology Group for his last 10 years there. In 1997 he was elected to Fellow of the IEEE for "his work in resonant-tunneling structures and contributions to understanding of high-speed semiconductor devices." Dr. Sollner has published over 50 articles in peer-reviewed journals, has given over 30 invited lectures, and holds 8 patents.

Talk Title: 2D Materials, Devices and Systems â A New Paradigm for Electronics and Optoelectronics
Abstract: In the past eight years, the research community has seen rapidly growing interests in two-dimensional (2D) crystals and their applications. The 2D carrier confinement in this versatile family of materials - whose members range from the well-known semi-metal graphene to the insulator boron nitride, or the semiconducting layered transition metal dichalcogenides (LTMD) -
confers to them unique band structures with correlated electronic states where charge, spin, orbital, valley and lattice degrees of freedom play an important role in defining their exceptional properties of carrier transport, tunable bandgaps, mechanical strength, piezoelectricity, thermoelectric effects and their interactions with light. These materials, still in their infancy, carry great potential to redefine nano-electronics, optoelectronics and their interaction with biological systems in the coming years. In this talk, I will present my work on understanding the material synthesis, device technology, carrier transport and the forward-looking engineering efforts to develop electronic applications based on 2D crystals at the device and circuit level. I will conclude with remarks on how these new materials are expected to change energy generation, biological sensors, medical electronics at both device and system levels.
Biography: Han Wang received the B.A. and M.Eng. degrees in electrical and information science, both with highest honors, from Cambridge University, England, in 2007 and 2008. He is currently pursuing the Ph.D. degree in Electrical Engineering and Computer Science at Massachusetts Institute of Technology (MIT). In summer 2012, he held an internship at IBM T. J. Watson Research Center. His research interests include the synthesis, device technology and
novel circuit applications of two-dimensional (2D) materials â including graphene, hBN, MoS2, WS2, etc., and their heterostructures â with emphasis on exploring both the fundamental understanding and forward-looking applications of 2D materials in ubiquitous electronics, optoelectronics, energy efficient applications, and interaction with biological systems. His past research also includes GaN-based III-V HEMTs for high power millimeter-wave applications and Si power electronic devices.
His work has been recognized with multiple awards including Cambridge University Agilent Prize, IEEE IEDM Best Student Paper Award, International Conference on Compound Semiconductor Manufacturing Technology (CS MANTECH) Best Student Paper Award and numerous fellowships. Mr. Wang has authored or coauthored more than 40 publications in distinguished journals and conferences, 8 of them invited, 1 book chapter and 1 patent.

Talk Title: Multifrontal Factorization on Heterogeneous Multicore Systems
Series: EE598 Seminar Course
Abstract: When solving the sparse linear systems that arise in mechanical computer aided engineering (MCAE), and other applications, the multifrontal method is particularly attractive as it transforms the sparse matrix factorization into an elimination tree of dense matrix factorizations. The vast majority of the floating point operations can be performed with calls to highly tuned BLAS3 routines, and near peak throughput is expected. Such computations are performed today on clusters of multicore microprocessors, often accelerated by by graphics processing units (GPUs). This talk discusses how concurrency in the multifrontal computation is processed with message passing (MPI), shared memory (OpenMP), and GPU accelerators (CUDA), exploiting the unique strengths of each.

Talk Title: Controlling quantum dynamics: from physical principles to quantum engineering?
Abstract: Since its discovery a century ago, quantum theory has proved hugely important in explaining many scientific phenomena and enabling new technologies from lasers to superconductors. The new frontier for quantum science and engineering is probing and coherently manipulating quantum dynamics. Systematic control of quantum dynamics is crucial for the development of novel quantum devices and applications in many areas from quantum information processing to quantum metrology and beyond. The latter goal has proved to be considerably more challenging but â as the 2012 Nobel prize in physics for example shows â much progress has been made in this area, opening the door for the development of new tools for control of quantum dynamics and quantum device design.
In the talk I will attempt to explain in basic terms what we mean by control of quantum systems and why control of quantum dynamics is important. I will give various examples and applications in physics, chemistry and biology, and explain different paradigms for quantum control and some of the theoretical tools developed for control design. The ideas and operation will be illustrated using simulations of quantum gates, information flow in quantum networks and molecular cooling.

Speaker: Dr. Seishi Takamura, NTT, Kanagawa, Japan
Talk Title: Evolutive Video Coding
Abstract: Evolutive methods based on genetic programming (GP) enable dynamic algorithm generation, and have been successfully applied to many areas such as plant control, robot control, and stock market prediction. However, conventional image/video coding methods such as JPEG, H.264/AVC and HEVC all use fixed (non-dynamic) algorithms without exception. In this talk, we introduce and investigate GP-based, highly nonlinear o pixel predictor to reduce lossless bit rate o image filter to enhance coding gaino transform to enhance coding gain that are specifically evolved for each input image.

Compression and Modern Data Processing
Mon, Mar 25, 2013 @ 10:30 AM - 11:30 AM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Thomas Courtade, Stanford University
Talk Title: Compression and Modern Data Processing
Abstract: At first glance, modern applications of data processing -- such as clustering, querying, and search -- bear little resemblance to the classical Shannon-theoretic problem of lossy compression. However, the ultimate goal is the same for modern and classical settings; both demand algorithms which strike a balance between the complexity of the algorithm output and the utility that it provides. Thus, when we attempt to establish fundamental performance limits for these "modern" data processing problems, elements of classical rate distortion theory naturally emerge.
Inspired by the challenges associated with extracting useful information from large datasets, I will discuss compression under logarithmic loss. Logarithmic loss is a penalty function which measures the quality of beliefs a user can generate about the original data upon observing the compressor's output. In this context, we characterize the tradeoff between the degree to which data can be compressed and the quality of beliefs an end user can produce. Notably, our results for compression under logarithmic loss extend to distributed systems and yield solutions to two canonical problems in multiterminal source coding.
I will also briefly discuss recent work on compression for identification, where we seek to compress data in a manner that preserves the ability to reliably answer queries of a certain form. This setting stands in stark contrast to the traditional compression paradigm, where the goal is to reproduce the original data (either exactly or approximately) from its compressed form. Under certain assumptions on the data sources, we characterize the tradeoff between compression rate and the reliability at which queries can be answered.
Biography: Thomas Courtade received the B.S. degree in Electrical Engineering from Michigan Technological University in 2007, and the M.S. and Ph.D. degrees in Electrical Engineering from UCLA in 2008 and 2012, respectively.

Speaker: Mina Rais-Zadeh, University of Michigan
Talk Title: Resonant MEMS for Timing and Integrated Sensing
Abstract: Invention of transistors and development of microelectronics unleashed a revolution in computing and communication. This revolution was mostly brought about by the fact that transistors and ICs could be miniaturized at an unprecedented level. Following the same trend, micro-electromechanical systems (MEMS), have been extensively employed for sensing and in mobile applications. In the next few decades, the MEMS field is expected to grow even more rapidly and find wider applications. A vast majority of systems used for sensing, communications, and signal processing rely on accurate clocking signals that are generated by micro-resonators. In this talk, I will go over the design of micro-resonators and resonant sensors, and discuss the application of these devices in timing and integrated sensing. I will explain the need for high quality factor and discuss the physical phenomena that limit the performance and scaling of resonant MEMS.

Talk Title: Energy-efficient On-chip Networks for Many-core Processors
Series: EE598 Seminar Course
Abstract: Energy-efficient processors are of paramount importance to designing computing systems that deliver superior performance-cost trade-offs. However, as the key communication subsystem of many-core processors, the on-chip network consumes a substantial percentage of the chipââ¬â¢s power and energy. In this talk, we analyze the energy consumption of on-chip networks and discuss the opportunities and challenges in reducing it, with an emphasis on minimizing static power by developing effective power-gating schemes. Two novel designs, namely node-router decoupling and proactive power-gating are proposed to provide architectural support for effective power-gating. These designs not only reduce static power, but also open up new opportunities for optimizing power-gating that is particularly needed for current on-chip networks.
Biography: Lizhong Chen is a PhD candidate working with Prof. Timothy Pinkston in the Ming Hsieh Department of Electrical Engineering at the University of Southern California, Los Angeles. His research focuses on energy-efficient and high-performance interconnection networks for chip multiprocessors and super-computers.

Speaker: Prof. Dimitrios Peroulis, Purdue University
Talk Title: High-Q Widely Tunable Miniaturized RF Front-Ends
Abstract: This seminar will begin by reviewing the state of the art in commercially-available RF MEMS and tunable front-ends. New directions for creating widely-tunable high-performance circuits in mobile form factors will be presented. We will discuss novel solutions at the fabrication technology, device, and sub-system levels. As an example, we will present unique three dimensional architectures for obtaining base-station quality tunable microwave filters in mobile form factors. These filters are based on low-cost silicon technology and simultaneously exhibit a very wide tuning range (>3:1) and a very high quality factor (Q>300-1,000) at 1-20 GHz and beyond. We will also present novel filter synthesis methodologies for developing field-programmable filter-arrays. Furthermore, we will also present power amplifier/filter co-design solutions. Specifically we will demonstrate that significant benefits can be obtained when co-designing power amplifiers with high-Q tunable bandpass filters for all-digital burst-mode transmitters and with high-Q tunable bandstop filters for obtaining high efficiencies in over 3:1 bandwidths.
