August 2018

Congratulations to professor Gordon Wetzstein! He has been presented with the Significant New Researcher Award for his work in advanced display hardware and display-specific rendering techniques.

Gordon develops displays that address a variety of perceptual challenges, including auto-stereoscopy, the elimination of vergence-accommodation conflict, and elimination of the need for observers with vision defects to wear corrective lenses.

His research has produced technology that corrects for myopia, hyperopia, or presbyopia. The Light Field Stereoscope, in 2015, presented a near-eye display technology that supports focus cues in virtual reality applications.

To utilize these display mechanisms, images are rendered with new algorithms that substantially increase image fidelity. The displays are not only designed, but also prototyped and tested. Indeed, several have been demonstrated in the SIGGRAPH Emerging Technologies exhibit.

Gordon is author or coauthor of over 80 conference and journal publications in Transactions on Graphics and in journals and proceedings in the fields of computer graphics, optics, information display, computer vision, and computational photography. These publications include contributions that support advanced display techniques, such as virtual reality camera rigs and cameras that capture both depth and velocity.

Please join us in congratulating Gordon on this terrific acknowledgement!

Congratulations to President Emeritus and EE Professor John Hennessy. He has been named the 2018 recipient of the Semiconductor Industry Association's Robert N. Noyce Award. The annual award recognizes a leader who has made outstanding contributions to the semiconductor industry in technology or public policy.

"Throughout his outstanding and influential career spanning more than four decades, John Hennessy has helped move the semiconductor industry forward, leading efforts to advance semiconductor technology and train future generations of electrical engineers," said John Neuffer, president and CEO, Semiconductor Industry Association. "John literally wrote the book on computer architecture design and has spearheaded semiconductor research that has helped make our industry what it is today. On behalf of the SIA board of directors, it is an honor to announce John's selection as the 2018 Robert N. Noyce Award recipient in recognition of his exceptional accomplishments."

John co-developed an approach to computer architecture that came to be known as the reduced instruction set computer (RISC) architecture, which involved significantly fewer transistors. The simpler design led to faster speeds, lower costs and shorter design times.

John joined EE in 1977 as an assistant professor and rose through the academic ranks to become Stanford's 10th president, serving in that role from 2000 until his retirement in 2016. In February 2018, Dr. Hennessy was appointed chairman of Alphabet Inc., parent company of Google.

 

Please join us in congratulating John on this well-deserved recognition!

July 2018

March 2018 marked the Inaugural John G. Linvill Distinguished Seminar on Electronic Systems Technology. Founded by Professor Emeritus James Gibbons and Professor H.S.- Philip Wong, the intention of the Linvill Seminar is to encourage the exploration of future trajectories for electrical engineering.

John Linvill was a revered figure at Stanford as much for his self-effacing and unpretentious style as for his engineering foresight and his commitment to the entrepreneurial spirit. Linvill helped launch Stanford on a trajectory that would ensure Stanford's continuing leadership in electronics engineering for decades to come. These lectures have been created to help us explore our paths going forward, and to honor John Linvill's enormous legacy as both a faculty member and a department chairman, whose commitment to excellence at Stanford continues to be a model for us all.

Featured speaker, Professor and President Emeritus John L. Hennessy, presented "The End of the Road for General Purpose Processors & the Future of Computing". The inaugural Linvill presentation is available through the video below.

 

Abstract of "The End of the Road for General Purpose Processors & the Future of Computing" – After 40 years of remarkable progress in VLSI microprocessors, a variety of factors are combining to lead to a much slower rate of performance growth in the future. These limitations arise from three different areas: IC technology, architectural limitations, and changing applications and usage. The end of Dennard scaling and the slowdown in Moore's Law will require more efficient architectural approaches than we have relied on to date. Although progress on general-purpose processors may hit an asymptote, domain specific architectures may be one attractive path for important classes of problems.

Yilong Geng (EE PhD candidate) presenting at NSDI '18
July 2018

Interdisciplinary research between professor Balaji Prabhakar, his team, and Google has produced a software clock synchronization system that can track time down to 100 billionths of a second.

The paper, presented at NSDI '18, describes a nanosecond-level clock synchronization that can be an enabler of a new spectrum of timing- and delay-critical applications in data centers.

The current, popular clock synchronization algorithm, NTP, can only achieve millisecond-level accuracy. Current solutions for achieving a synchronization accuracy of 10s-100s of nanoseconds require specially designed hardware throughout the network for combatting random network delays and component noise or to exploit clock synchronization inherent in Ethernet standards for the PHY.

The research team presents HUYGENS, named for the Dutch physicist Christiaan Huygens, who invented the pendulum clock in 1656. HUYGENS is a software clock synchronization system that uses a synchronization network and leverages three key ideas. First, coded probes identify and reject impure probe data—data captured by probes which suffer queuing delays, random jitter, and NIC timestamp noise. HUYGENS then processes the purified data with Support Vector Machines, a widely-used and powerful classifier, to accurately estimate one-way propagation times and achieve clock synchronization to within 100 nanoseconds. Finally, HUYGENS exploits a natural network effect—the idea that a group of pair-wise synchronized clocks must be transitively synchronized— to detect and correct synchronization errors even further.

The importance of technical advances in measuring time was underscored by European regulations that went into effect in January and that require financial institutions to synchronize time-stamped trades with microsecond accuracy.

Being able to trade at the nanosecond level is vital to Nasdaq. Two years ago, it debuted the Nasdaq Financial Framework, a software system that it has envisioned eventually trading everything from stocks and bonds to fish and car-sharing rides.

The new synchronization system will make it possible for Nasdaq to offer "pop-up" electronic markets on short notice anywhere in the world, Mr. Prabhakar said. He cited the World Cup as a hypothetical example of a short-term electronic marketplace.

"There are tickets needed, housing, people will need transportation," he said. "Think of an electronic market almost like a massive flea market hosted by Nasdaq software."

The HUYGENS team is Yilong Geng (EE PhD candidate), Shiyu Liu (EE PhD candidate), and Zi Yin (EE PhD candidate), Ashish Naik (Google Inc.) EE professors Balaji Prabhakar and Mendel Rosenblum, and Amin Vahdat (Google Inc.)

Congratulations to emeritus professor Jim Gibbons! Recognized by Avenidas for his significant contributions in the social well-being of the community at large.

"[...T]he former Dean of the School of Engineering at Stanford, is known internationally for his important achievements in education and for his development of fabrication technologies that were foundational for the modern semiconductor industries in Silicon Valley and around the world. Less well known is the fact that his work has also contributed significantly to the social well-being of our community at large. Jim also served on no less than 13 boards in the Valley (among them Cisco, Raychem, SRI, Lockheed Martin, PARC, and more). In the educational field, he vastly expanded and improved the Stanford Instructional Television Network, which provided topnotch education via television to thousands of engineers at local companies. Again, this provided a crucial piece of "infrastructure" to the Valley, and was a forerunner of present internet courses.

His engagement with the Santa Clara Juvenile Hall in 1996 led him and his colleagues at SERA Learning to develop a successful program that teaches at-risk youth how to manage their anger and walk away from fights. SERA's "Skills for Managing Anger" course has since be used in 355 schools and juvenile justice applications across the country, including Columbine High School and NYC after 9 /11. It included new student centered teaching methods that Jim had developed for the Stanford Video program. Jim credits his wife Lynn who supported him in all his endeavors. He says: "She encouraged me to do things that would serve the needs of others." Avenidas is thrilled to celebrate Jim's amazing contributions and success."

The 2018 Lifetimes of Achievement honorees include Nancy Mueller, Dick Mansfield, Ellie Mansfield, Kristine Erving, John Erving, Christy Holloway and Jim Gibbons.
