Dr. Changhee Jung and Dr. Dongyoon Lee receive a NSF award

Changhee Jung and Dongyoon Lee, assistant professors in computer science, received a NSF award for a project titled “Compiler and Architectural Techniques for Soft Error Resilience”.  Professor Jung is the principal investigator and Professor Lee will serve as co-principal investigator.  Read the full abstract below or click here:

Due to technology scaling, electronic circuits are becoming more susceptible to radiation-induced soft errors also known as transient faults. Soft errors may lead to application crash or even worse, silent data corruptions (SDC) that are not caught by the error detection logic but may cause the application to produce incorrect output. Another serious problem is the rise of detected unrecoverable errors (DUE) that often directly impact the reliability of any computer applications. The challenge is to achieve soft error resilience in a way that does not significantly increase the performance overhead, power consumption, and complexity of underlying hardware. To this end, this project designs and develops low-cost hardware/software cooperative techniques for soft error resilience. The resulting artifacts and technologies are expected to contribute to the nation’s competitiveness by addressing the challenge of building reliable computing systems in the presence of soft errors.

This research involves three intermediate research goals: design novel microarchitecture, that dynamically verifies the correctness of the processor core execution based on sensor-based soft error detection, to achieve soft error resilience at low cost; design a compiler that forms verifiable and recoverable regions in the presence of soft errors and provides relevant program analysis techniques; and design and develop compiler optimization and microarchitectural techniques that significantly reduce the verification overhead. This project will create tools and technologies for realization of soft error resilient computing systems, contributing fundamentally to the fault tolerance research community. Adoption of the resulting compiler and microarchitectural techniques will impact a broad range of any disciplines that need correct computation results thus requiring reliable computing systems, covering from mobile devices to high-performance large-scale computing systems. Consequently, use of the resulting technologies will make the execution of current and emerging applications much more reliable, and therefore directly affect our way of life.

Dr. Ing-Ray Chen receives the 2015 IEEE Communications Society William R. Bennett Prize

Dr. Ing-Ray Chen, NCR Campus CS Program Director and Professor of Computer Science received the 2015 IEEE Communications Society William R. Bennett Prize in the Field of Communications Networking. This award was presented at IEEE 2015 International Conference on Communications in London, UK, during the Awards Ceremony and Luncheon on Tuesday, June 9, 2015 and comes with a plaque and a honorarium of $1,000. Dr. Chen worked together with his PhD graduates, Dr. Fenye Bao and Dr. Jin-Hee Cho, and his former postdoc, Dr. MoonJeong Chang.

Prof. Chen won the award with his paper entitled, ‘Hierarchical Trust Management for Wireless Sensor Networks and its Applications to Trust-Based Routing and Intrusion Detection. Every year the IEEE Communications Society selects an original paper published in the IEEE/ACM Transactions on Networking or the IEEE Transactions on Network and Service Management in the previous 3 calendar years as the winner for this award on the basis of quality, originality, utility, timeliness, and clarity of presentation.

According to Dr. Chen, the paper advances the basic knowledge on defending selfish and malicious nodes in wireless sensor networks (WSNs). The methodology proposed in this paper can be applied to a wide range of WSN applications.  Read More Here

Dr. Aditya Prakash receives Facebook Faculty Gift

Aditya Prakash, assistant professor in the Department of Computer Science, received a Facebook Faculty Gift.  This gift is one of 10 such awards given at this time from the Facebook Faculty Program.  According to Aditya, “The award will support novel information diffusion related research focusing on understanding, predicting and countering virality on social-media websites and platforms.  For example, some of the questions we will be studying include: What content could go viral? How much and when? Given a context, how to identify and counter negative viral campaigns?”

Mapping the Fourth of July in the American Civil War Era

Professor Kurt Luther’s National Archives grant proposal was accepted.  The project is through the NHPRC’s “Literacy and Engagement with Historical Records” program.  Paul Quigley (History) is the PI.  Kurt Luther (Computer Science) is Co-PI, along with David Hicks (Education).

The project titled “Mapping the Fourth of July in the American Civil War Era: A Crowdsourced Digital Archive” will use a variety of primary sources to build a website through which college and high school students, Civil War enthusiasts, and the general public can analyze and discuss how different regions celebrated the Fourth of July during the Civil War.
