Spring Explore USC
Mon, Apr 16, 2018
Viterbi School of Engineering Undergraduate Admission
University Calendar
Spring Explore is a full-day program running from 8:30am-5pm. The day includes a presentation from the Office of Admission, a USC Campus Tour, and visit with us in the Viterbi School of Engineering. During your time with us you will learn what your life will be like as an engineering student at USC, meet some of our current engineering students, see facilities and labs, and get your questions answered about the enrollment process, housing, and your "next steps".

CS Colloquium: Srivatsan Ravi (ISI USC) - Synchronization using Transactions: Lower bounds and Algorithms
Mon, Apr 16, 2018 @ 11:00 AM - 12:00 PM
Thomas Lord Department of Computer Science
Conferences, Lectures, & Seminars
Speaker: Srivatsan Ravi, ISI USC
Talk Title: Synchronization using Transactions: Lower bounds and Algorithms
Series: CS Colloquium
Abstract: Designing algorithms to exploit today's distributed computing platforms ranging
from general-purpose multicore CPUs, cloud infrastructures to domain-specific decentralized computing systems emphasizes the need for designing robust and fault-tolerant synchronization protocols. However, traditional techniques for synchronization are either too coarse-grained to exploit concurrency or require application-specific fine-grained synchronization.
The Transactional Memory (TM) abstraction is a synchronization mechanism
for multicore programming proposed as a middle ground: it intends to combine an easy-to-use programming model with an efficient utilization of hardware concurrency. TM allows the programmer to speculatively execute sequences of shared-memory operations as atomic in-memory transactions with safe semantics: state witnessed by each transaction is consistent with some sequential execution. Thus, the programmer can design applications having largely sequential semantics in mind and let TM take care, at run-time, of dealing with problems associated with process asynchrony and adversarial failures.
In this talk, we focus on a model for hybrid TMs that exploits hardware extensions in prevalent CPU architectures to support small transactions. We present lower bound proof constructions for implementing safe hybrid transactions and its implications for the complexity of concurrent data structures. We conclude by outlining how transactions as a synchronization mechanism can serve as highly robust universal constructions for domain-specific distributed computing models.
This lecture satisfies requirements for CSCI 591: Research Colloquium. Please note, due to limited capacity, seats will be first come first serve.
Biography: Srivatsan Ravi is a computer scientist at the Information Sciences Institute in University of Southern California (USC). His research interests are centered around the theory and practice of distributed computing. Specifically, he works on algorithms and lower bounds for fault-tolerant distributed systems. His research is motivated by emerging new hardware trends that require a new abstract computation model or via introduction of distributed computing techniques to domains where the sequential implementation continues to be state-of-the-art.
He received his Ph.D. degree from Technical University of Berlin in Germany, where he received the Marie Curie Ph.D. Fellowship and was a member of Deutsche-Telekom Labs, Berlin. His Masters degree is from Cornell University, U.S.A and his Bachelors degree is from Anna University, India.

Center for Systems and Control (CSC@USC) and Ming Hsieh Institute for Electrical Engineering
Mon, Apr 16, 2018 @ 02:00 PM - 03:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: John Baras, The Institute for Systems Research, University of Maryland
Talk Title: Networked Cyber-Physical Systems (Net-CPS)
Series: Joint CSC@USC/CommNetS-MHI Seminar Series
Abstract: We describe recent results on foundational aspects of modeling, architecture and performance of networked cyber-physical systems. These include: multi-layer multigraph models, constrained coalitional games, analysis of trust and mistrust in collaboration, dynamics of signed graphs, distributed consensus with adversaries, new concepts of value of information and event-driven inference and decision making, non-commutative probability models. We conclude with directions for future research.
Biography: John Baras is with the University of Maryland College Park, where he holds he endowed Lockheed Martin Chair in Systems Engineering. He received the Diploma in Electrical and Mechanical Engineering from the National Technical University of Athens, Greece, 1970; the M.S. and Ph.D. degrees in Applied Mathematics from Harvard University 1971, 1973. Since 1973, he has been a faculty member in the Electrical and Computer Engineering Department, and in the Applied Mathematics, Statistics and Scientific Computation Program, at the University of Maryland College Park. Founding Director of the Institute for Systems Research (ISR), 1985 to 1991. Since 1992, Founding Director of the Maryland Center for Hybrid Networks (HYNET). Since 2013, Guest Professor at the Royal Institute of Technology (KTH), Sweden. IEEE Life Fellow, SIAM Fellow, AAAS Fellow, NAI Fellow, IFAC Fellow, AIAA Associate Fellow, and a Foreign Member of the Royal Swedish Academy of Engineering Sciences (IVA).
