  • Energy Efficient Memory Circuits: From IoT to Exascale Systems and Beyond

    Mon, Apr 04, 2016 @ 10:30 AM - 11:30 AM

    Ming Hsieh Department of Electrical and Computer Engineering

    Conferences, Lectures, & Seminars


    Speaker: Dr. Jaydeep Kulkarni, Staff Research Scientist, Circuit Research Scientist, Circuit Research Lab, Intel Corporation

    Talk Title: Energy Efficient Memory Circuits: From IoT to Exascale Systems and Beyond

    Abstract: With the rapid advances in computing systems spanning from billions of IoTs (Internet of Things) to high performance exascale super computers, energy efficient design is an absolute must. It is projected that by 2020, around 50 billion internet connected devices will be deployed generating hundreds of zettabytes (1021 bytes) of data. It is estimated that embedded memories can occupy up to 70% of the die area in these devices. These trends clearly indicate the paramount importance of developing energy efficient, dense memory circuits and systems across the entire compute continuum. I will present two energy efficient memory solutions one geared for IoT systems while the other targeted at high performance exascale systems. With extremely low energy budget, IoT systems would need ultralow voltage circuits for always-ON sensing and computing. Low voltage Static Random Access Memory (SRAM) operation is challenging due to conflicting read-stability vs write-ability requirements. I will present two Schmitt Trigger based SRAMs having built-in process variation tolerance for extreme low voltage operation. Measurement results from 130nm test-chips confirm successful operation up to 150mV [JSSC'07, TVLSI'12]. At the other end of compute spectrum consisting of high performance exascale systems, fixed voltage/ frequency guardbands are applied to the nominal operating specifications to guarantee reliable operation in the presence of temperature variations, voltage supply droops, and transistor aging induced degradation. Since most of the systems operate at nominal conditions, the necessary guardbands for these infrequent dynamic variations significantly limit the system energy efficiency. I will present adaptive and resilient domino register file design techniques to realize a unified framework for logic + memory operating on same voltage/frequency domain. Measurement results from a 22nm test-chip demonstrate 21% higher throughput with 67% improved energy efficiency [ISSCC'15, JSSC'16]. I will conclude the seminar by highlighting the interesting areas in memory research for the development of next generation of energy efficient computing systems. These aspects include emerging non-volatile technologies such as STT, and RRAM memories, memory scaling using monolithic 3D integration, logic-in-memory organization / architectures for non von Neumann computing models such as neuromorphic computing, and security/privacy issues in next zettabytes of data.

    Ming Hsieh Department of Electrical and Computer Engineering

    Conferences, Lectures, & Seminars


    Speaker: Min-Hsiu Hsieh, University of Technology, Sydney

    Talk Title: Markovian Evolution of a Quantum Ensemble and its Long-Term Behavior

    Abstract: We extend the theory of quantum Markov processes on a single quantum state to a broader theory that covers Markovian evolution of an ensemble of quantum states. This generalizes Lindblad's formulation of quantum dynamical semigroups. Our formalism includes an explicit form of semigroups, their time derivative-” the infinitesimal generator, a carr'e du champ operator, and matrix *phi-entropy. We find a matrix *phi-Sobolev inequality that governs the exponential decay of the these matrix *phi-entropy. Special cases of the matrix *phi-entropy evaluate to the Holevo quantity and the variance of the ensemble, which allows us to relate our formalism to classical coding over quantum channels. In particular, we show that the convergence rates of two special semigroups-the depolarizing and phase-damping channels-can be explicitly computed. They result in fundamentally different equilibrium situations, for which there is no classical analogy.

    Biography: Min-Hsiu Hsieh received his PhD degree in electrical engineering from the University of Southern California, Los Angeles, in 2008. From 2008-2010, he was a Researcher at the ERATO-SORST Quantum Computation and Information Project, Japan Science and Technology Agency, Tokyo, Japan.

    Ming Hsieh Department of Electrical and Computer Engineering

    Conferences, Lectures, & Seminars


    Speaker: Edward A. Lee, Professor, University of California Berkeley

    Talk Title: Resurrecting Laplace's Demon: The Case for Deterministic Models for Cyber-Physical Systems

    Abstract: In 1814, Pierre-Simon Laplace published an argument for determinism in the universe, arguing that if someone (a demon) were to know the precise location and momentum of every atom in the universe, then their past and future values for any given time are completely determined and can be calculated from the laws of classical mechanics. This principle, of course, has been roundly invalidated by quantum mechanics, and yet the laws of classical mechanics continue to be extremely useful for prediction. In this talk, I will argue that models plays different (complementary) roles in engineering and science, and that deterministic models have historically proved proved even more valuable in engineering than in science.

    Cyber-physical systems, which combine computation with physical dynamics, may seem on the surface to be a particularly poor match for deterministic models. I will argue that the next big advance in engineering methods must include deterministic models for CPS, and I will show that such models are both possible and practical.

  • CS Colloquium: Chang Liu (University of Maryland, College Park) - Secure Cloud Computing - A Programming Language Approach

    Tue, Apr 05, 2016 @ 11:00 AM - 12:00 PM

    Thomas Lord Department of Computer Science

    Conferences, Lectures, & Seminars


    Speaker: Chang Liu, University of Maryland, College Park

    Talk Title: Secure Cloud Computing - A Programming Language Approach

    Series: CS Colloquium

    Abstract: This lecture satisfies requirements for CSCI 591: Computer Science Research Colloquium

    The big data era has dramatically transformed our lives; however, security incidents such as data breaches put sensitive data (e.g. photos, identities, genomes) at risk. To protect users' data privacy, there is a growing trend to build secure cloud computing systems, which enables computation over two or more parties' sensitive data, while revealing nothing more than the results to the participating parties. Conceptually, privacy-preserving computing systems leverage cryptographic techniques (e.g. secure multiparty computation) and trusted hardware (e.g. secure processors) to instantiate a "secure" abstract machine consisting of a CPU and encrypted memory, so that an adversary cannot learn information through either the computation within the CPU or the data in the memory. Unfortunately, evidence has shown that, side channels (e.g. memory accesses, timing, and termination) in such a "secure" abstract machine may potentially leak highly sensitive information including cryptographic keys that form the root of trust for the secure systems.

    I conduct synergistic research to bridge cryptography and programming language techniques to address
    this problem. My research broadly expanded the investigation of a research direction called trace oblivious computation, where I employ programming language techniques to prevent side channel information leakage. In this talk, I will discuss my work on two promising approaches, i.e. secure-processor and secure multiparty computation, toward building a secure cloud computing system. I will focus on both theoretical development to enforce formal security, as well as practical system building to yield the state-of-the-art results.


    Biography: Chang Liu is a PhD candidate in the Department of Computer Science at University of Maryland, College Park, where he works in the Maryland Cybersecurity Lab with his advisors Michael Hicks and Elaine Shi. His work broadly expanded the investigation of the research direction of trace oblivious computation, which made significant impact on trusted hardware-based secure computation and cryptography-based secure multiparty computation. He is the recipient of John Vlissides Award (2015) and University of Maryland's Outstanding Early Graduate Student Award (2014). His papers has received a NSA Best Scientific Cybersecurity Paper Award (2013), the Best Paper Award of ASPLOS (2015), and 1st Best Paper Award in Applied Cyber Security Paper at CSAW (1st Place, 2015). His ObliVM system won the HLI Award for Secure Multiparty Computation in the iDash Secure Genomics Analysis Competition (2015).

  • Smart Data Pricing

    Tue, Apr 05, 2016 @ 11:00 AM - 12:00 PM

    Ming Hsieh Department of Electrical and Computer Engineering

    Conferences, Lectures, & Seminars


    Speaker: Carlee Joe-Wong, Princeton University

    Talk Title: Smart Data Pricing

    Abstract: Data traffic has increased sharply over the past decade and is expected to grow further as Internet applications from video streaming to cloud storage become ever more popular. Yet data network capacity is not expanding fast enough to handle this exponential growth, leading service providers to change their mobile data plans in an effort to reduce congestion. Inspired by these ongoing changes and building on work from the 1990s, smart data pricing (SDP) aims to rethink data pricing for tomorrow's networks. In this talk, I will focus on the temporal and content dimensions of SDP and then briefly discuss the problem of fairly allocating network resources to applications with diverse resource needs. Time-dependent pricing (TDP) proposes to lower short-lived peaks in network congestion by incentivizing users to shift their data usage to less congested times. While TDP has been used in industries such as smart grids, TDP for mobile data presents unique challenges, e.g., it is difficult to predict how users will react to the prices on different days. Thus, we developed algorithms that continually infer users' changing responses to the offered prices, without collecting private data usage information. We implemented these algorithms in a prototype system, which we used to conduct the first field trial of TDP for mobile data. We showed that our TDP algorithms led to significantly less temporal fluctuation in demand, benefiting the service provider and lowering users' data prices overall.

    Sponsored data, an emerging form of data pricing offered by AT&T, allows content providers to subsidize their users' data traffic; the resulting revenue can be used to expand existing data networks. We consider the impact of sponsored data on different content providers and users, showing that cost-aware users and cost-unaware content providers reap disproportionate benefits. Simulations across representative users and content providers verify that sponsored data may help to bridge the digital divide between different types of users, yet can exacerbate competition between content providers.


    Biography: Carlee Joe-Wong is a Ph.D. candidate and Jacobus fellow at Princeton University's Program in Applied and Computational Mathematics. She is interested in mathematical aspects of computer and information networks, including work on smart data pricing and fair resource allocation. Carlee received her A.B. in mathematics in 2011 and her M.A. in applied mathematics in 2013 both from Princeton University. In 2013-“2014, she was the Director of Advanced Research at DataMi, a startup she co-founded from her data pricing research. Carlee received the INFORMS ISS Design Science Award in 2014 and the Best Paper Award at IEEE INFOCOM 2012. She was a National Defense Science and Engineering Graduate Fellow (NDSEG) from 2011 to 2013.

    Speaker: Aaron Schulman , Stanford

    Talk Title: Why applications are still draining our batteries, and how we can help.

    Series: CS Colloquium

    Abstract: This lecture satisfies requirements for CSCI 591: Computer Science Research Colloquium

    Application developers lack tools to profile and compare the energy consumption of different software designs. This energy-optimization task is challenging because of unpredictable interactions between the application and increasingly complex power management logic. Yet, having accurate power information would allow application developers to both avoid inefficient designs and discover opportunities for new optimizations.

    In this talk, I will show that it is possible to accurately measure system-level power and attribute it to application activities. I will present BattOr, a portable, easy-to-use power monitor that provides developers with a profile of the energy consumption of their designs-”without modifications to hardware or software. I will show how Google developers are using BattOr to improve Chrome's energy efficiency. I will also show how fine-grained understanding of cellular power at different signal strengths enables novel energy optimizations. Finally, I will describe my future plans to attribute system-level power to individual hardware components and to investigate opportunities presented by instrumenting every server in a data center with fine-grained power monitoring.

    Biography: Aaron Schulman is a Postdoctoral Scholar at Stanford working with Sachin Katti; he earned his Ph.D. in Computer Science from the University of Maryland, where he was advised by Neil Spring. His research interests are in low-power embedded systems, wireless communication, and network measurement. Aaron's research on the BattOr power monitor has been funded by Google, is being commercialized by his startup Mellow Research, and is becoming Google's de facto standard tool for measuring the energy consumption of the Chrome web browser. For his dissertation, Aaron provided the first observations of fundamental factors that limit the reliability of the Internet's critical last-mile infrastructure. His dissertation was selected to receive the the 2013 ACM SIGCOMM Doctoral Dissertation Award. http://stanford.edu/~aschulm

    Speaker: Dr. Samet Oymak, Caltech

    Talk Title: Sharp tradeoffs for randomized numerical algorithms: Let the theory meet practice

    Series: CommNetS

    Abstract: Randomized numerical algorithms are fundamental for a variety of problems in signal processing and machine learning. Examples include sparse signal processing and dimensionality reduction for faster machine learning. These algorithms come with various tradeoffs involving the amount of data, computational resources and statistical precision. Characterization of these tradeoffs is crucial for correct hyperparameter selection, time sensitive optimization and eventual performance of the algorithms. In this talk, we describe our recent results on how to accurately predict these tradeoffs in multiple scenarios which helps us further close the gap between theory and practice.

    Biography: Samet Oymak is a software engineer at Google. Prior to that, he was a fellow at Simons Institute and a postdoctoral scholar in the AMPLab at UC Berkeley. He received his BS from Bilkent University in 2009 and his MS and PhD from Caltech in 2014, all in electrical engineering.

    Speaker: Rajan N. Chokshi , Accutant Solutions

    Talk Title: Artificial Lift Applications in Unconventional & Tight Reservoirs

    Abstract: The unique challenges of hydrocarbon production from shale reservoirs have required operators to take a fresh approach to asset development. Decisions about well placement, geometry, completion, and production are interrelated and must be addressed as part of life cycle planning. Artificial lift systems must be configured for rapidly changing and dynamic production environments. Migration from one lift technology to another is often required for wells that typically experience steep production decline rates. This presentation discusses the unique challenges of unconventional production and presents current production trends supported by field examples. Recommendations for optimizing production from shale and tight reservoirs are presented.

    Title: Combating Adversaries under Uncertainties in Real-world Security Problems: Advanced Game-theoretic Behavioral Models and Robust Algorithms

    Location: EEB 248

    Abstract:


    Security is a global concern. Real-world security problems range from domains such as the protection of ports and airports from terrorists to protecting forests and wildlife from smugglers and poachers. A key challenge in solving these security problems is that security resources are limited; not all targets can be protected all the time. Therefore, security resources must be deployed intelligently, taking into account responses of attackers and potential uncertainties over their types, preference, and knowledge. Stackelberg Security Games (SSG) have drawn a significant amount of interest from security agencies. SSG-based decision aids are in widespread use for the protection of assets such as major ports in the US and airport terminals.

    My research focuses on addressing uncertainties in SSGs --- one recognized area of weakness in SSGs. For example, adversary payoff values can be extremely difficult to assess and are generally characterized by significant uncertainty. My thesis provides innovative techniques and significant advances in addressing these uncertainties in SSGs. First, in many security problems, human adversaries are known to be boundedly rational, and often choose targets with non-highest expected value to attack. I introduce novel behavioral models of adversaries which significantly advance the state-of-the-art models in capturing the adversaries' decision making. More specifically, my new model for predicting poachers'behavior in wildlife protection is the first game-theoretic model which takes into account key domain challenges including the imperfect poaching data and complex temporal dependencies in the poachers' behavior. The superiority of my new models over the existing ones is demonstrated via extensive experiments based on the biggest real-world poaching dataset collected in a national park in Uganda over 12 years. Second, my research also focuses on developing new robust algorithms which address uncertainties in real-world security problems. I present the first unified maximin-based robust algorithm - a single algorithm -to handle all different types of uncertainties explored in SSGs. Furthermore, I propose a less conservative decision criterion; minimax regret for generating new, candidate defensive strategies that handle uncertainties in SSGs. In fact, this is the first time minimax regret has ever been used for addressing uncertainties in SSGs. I then present novel robust algorithms to compute minimax regret for addressing payoff uncertainty.

    A contribution of particular significance is that my work is deployed in the real-world; I have deployed my robust algorithms and behavioral models for the PAWS system, which is currently being used by NGOs (Panthera and Rimba) in a conservation area in Malaysia.

    Talk Title: Prominent features of rumors in social networks

    Series: Artificial Intelligence Seminar

    Abstract: *This is the First of 2 AI Seminar Talks on FRI. 4/8

    Social psychology literature defines a rumor as a story in general circulation without confirmation or certainty to facts. Rumors arise in the context of ambiguity, when the meaning of a situation is not readily apparent or when people feel an acute need for
    Security. Rumors hence are a powerful, pervasive, and persistent force affecting people and groups. This talk will introduce efforts on identifying rumors using massive data in social media. I will discuss the distinct patterns we observed from rumor diffusions in terms of the following aspects: temporal, structural, and linguistic.

    Title: Towards Addressing Spatio-Temporal Aspects in Security Games

    PhD Candidate: Fei Fang

    Committee members: Milind Tambe (advisor), Leana Golubchik, Jelena Mirkovic, Suvrajeet Sen, Shaddin Dughmi

    Location: RTH 526

    Time: April 8, 1pm-3pm


    Abstract:
    Game theory has been successfully used to handle complex resource allocation and patrolling problems in security and sustainability domains. More specifically, real-world applications have been deployed for different domains based on the framework of ``security games'', where the defender (e.g., security agency) has a limited number of resources to protect a set of targets from an adversary (e.g., criminal, terrorist). Whereas the first generation of security games research provided algorithms for optimizing security resources in mostly static settings, my thesis advances the state-of-the-art to a new generation of security games, handling massive games with complex spatio-temporal settings and leading to real-world applications that have fundamentally altered current practices of security resource allocation. My thesis provides the first algorithms and models for advancing key aspects of spatio-temporal challenges in security games, including (i) continuous time; (ii) continuous space; (iii) frequent and repeated attacks; (iv) complex spatial constraints.

    First, focusing on games where actions are taken over continuous time (for example games with moving targets such as ferries and refugee supply lines), I propose a new game model that accurately models the continuous strategy space for the attacker and provide an efficient solution that uses compact representation for both the defender and the attacker's strategy space. Second, for games where actions are taken over continuous space (for example games with forest land as a target), I provide an algorithm computing the optimal distribution of patrol effort. Third, my work addresses challenges with one key dimension of complexity -- frequent and repeated attacks. Motivated by the repeated interaction of players in domains such as preventing poaching and illegal fishing, I introduce a novel game model that deals with frequent and repeated attacks and provide algorithms to plan effective sequential defender strategies. Furthermore, I handle complex spatial constraints that arise from the problem of designing optimal patrol strategy given complex topographical information.

    My thesis work has led to two applications which have been deployed in the real world and have fundamentally altered previously used tactics, including one used by the US Coast Guard for protecting the Staten Island Ferry in New York City in past few years and another deployed in a protected area in Southeast Asia to combat illegal poaching.

    Series: Natural Language Seminar

    Abstract: The increasing growth of network data such as linked documents on the Web and social networks, has imposed great challenges on automatic data analysis. We study the problem of learning representations of network data, which is of critical for applications including data classification, ranking and link prediction. We present neural network embedding algorithms to learn distributed representations of network data that capture the deep context of each data point, and human cognition in navigation data. To improve the scalability of our algorithms, we use efficient optimization and sampling methods.
