YY Zhou / More Reliable Computing

Calit2's Tiffany Fox wrote a nice profile on Yuanyuan (YY) Zhou, a computer science professor here at the Jacobs School of Engineering.

“People always ask why their systems fail, and the computer industry is starting to pay attention to this reliability issue,” explains Zhou, who joined the UCSD Department of Computer Science and Engineering (CSE) in the Jacobs School of Engineering in the summer of 2009. “Fundamentally, my research is about making computer systems less vulnerable to attacks so they crash less. When Windows crashes, it’s more of an inconvenience, but when an e-commerce site crashes it can really be a problem.”


Zhou is the first holder of the Qualcomm Endowed Chair in Mobile Computing. The chair is one of four established in the Jacobs School of Engineering through Qualcomm’s original $15 million commitment to the California Institute for Telecommunications and Information Technology (Calit2).

Software for Efficient Computing in the Age of Nanoscale Devices

San Diego, CA, August 19, 2010 -- As semiconductor manufacturers build ever smaller components, circuits and chips at the nano scale become less reliable and more expensive to produce. The variability in their behavior from device to device and over their lifetimes – due to manufacturing, aging-related wear-out, and varying operating environments – is largely ignored by today’s mainstream computer systems.
Now a visionary team of computer scientists and electrical engineers from six universities is proposing to deal with the downside of nanoscale computer components by re-thinking and enhancing the role that software can play in a new class of computing machines that are adaptive and highly energy efficient.

The National Science Foundation (NSF) today awarded a $10 million, five-year grant to researchers who will explore “Variability-Aware Software for Efficient Computing with Nanoscale Devices.” The grant is part of the funding agency’s Expeditions in Computing program, which rewards far-reaching agendas that “promise significant advances in the computing frontier and great benefit to society.”

Researchers on the team include: Rajesh Gupta, Ranjit Jhala, Sorin Lerner, Tajana Simunic Rosing, Steve Swanson and Yuanyuan (YY) Zhou from UC San Diego; Lara Dolecek and Puneet Gupta from UCLA Engineering; Subhasish Mitra from Stanford; Dennis Sylvester from Michigan; Rakesh Kumar from UIUC’s Coordinated Science Laboratory; as well as Nikil Dutt and Alex Nicolau from UCI’s Center for Embedded Computer Systems.

Robot Swarms on DC Airwaves

Last November, Jorge Cortes became the PI on an NSF grant entitled “Distributed Ocean Monitoring via Integrated Data Analysis of Coordinated Buoyancy Drogues.”

The oil spill in the Gulf of Mexico is one of the kinds of situations this technlogy would be used in, when it's ready to move from the lab to the ocean.

This technology was recently featured in the weekly radio segment produced by the National Academy of Engineering (NAE). You can listen to the very short piece here: WTOP, which is a huge news-only radio station in the Washington DC area.


The first paragraph of the 2009 press release from the Jacobs School of Engineering is below.

To develop control systems for “swarms” of miniature robotic ocean explorers that could one day help predict where ocean currents will carry oil spills, engineers at the UC San Diego Jacobs School of Engineering recently won a nearly $1.5 million grant from the National Science Foundation. The engineers are leading the development of the control systems for swarms of small, inexpensive, underwater robotic ocean drifters that researchers at Scripps Institution of Oceanography and the Department of Mechanical and Aerospace Engineering at UC San Diego are designing, building and deploying.
