Open Access for Publications

Posted by Alfred Spector, Vice President, Engineering

The Association for Computing Machinery (ACM) recently announced a new option for publication rights management, wherein researchers can choose to pay for the public to have perpetual open access to the publication. Google applauds this new option, and today we are announcing that we will pay the open access fees for all articles by Google researchers that are published in ACM journals. IEEE also has an open access option for some of its publications, and we also pay the open access fee for them and for publications in like organizations.

Google has always believed that by improving access to the world’s knowledge, we can help improve everyone’s lives. When it comes to scientific research, we have consistently said that open access to publications speeds up research, accelerates innovation, and helps grow the global economy.

Policies like ACM’s continue to demonstrate the sustainability of open access publishing. It will also provide better access to the papers that we write at Google. We encourage researchers everywhere to pursue open access options whenever publishing articles, and to continue to make publications available as widely as possible, within your rights.

Congratulations to three Googlers elected ACM Fellows

It gives me great pleasure to share that the Association for Computing Machinery (ACM) has announced that three Googlers have been elected ACM Fellows in 2011. The ACM is the world’s largest educational and scientific computing society, and the Fellows Program celebrates the exceptional contributions of leaders in the computing field. This year the society has selected Amit Singhal, Peter S. Magnusson and Amin Vahdat for their outstanding work, which has provided fundamental knowledge to the field.

The recently-named Fellows join 14 prior Googler ACM Fellows and other professional society honorees in exemplifying our extraordinarily talented people. On behalf of Google, I congratulate our colleagues. They embody Google’s commitment to innovation with impact, and I hope that they’ll serve as inspiration to students as well as the broader community of computer scientists.

You can read more detailed summaries of their achievements below, including the official citations from the ACM.

Dr. Amit Singhal, Google Fellow

For contributions to search and information retrieval

Since 2000, Dr. Amit Singhal has been pioneering search as the technical lead for Google's core search algorithms. He is credited with most of the information retrieval design decisions in Google Search – a massive system that has responded to hundreds of billions of queries. More than anyone, Amit has a deep understanding of Google’s entire algorithmic system. He is responsible for prioritization and has overseen the development of numerous algorithmic signals and their progression over time. He is the clear thought and managerial leader who has led critically important initiatives at the company. Among many other things, Amit catalyzed Universal Search, which returns multi-modal results from all available corpora; he was the force behind Realtime Search, which returns results from dynamic corpora with low latency; and he championed Google Instant, which returns search results as the user types.

Prior to joining Google, Amit boasted a prolific publication record averaging 5 publications/year from 1996-9 while at AT&T Labs. Since that time, you could say Google Search has been one long, sustained publication demonstrating a constant advancement in the state of the art of information retrieval.


Peter S. Magnusson, Engineering Director

For contributions to full-system simulation

Peter has made a tremendous impact by driving full-system simulation. His approach was so advanced, it can be used in real world production of commercial CPUs and prototyping of system software. Starting in 1991, Peter began to challenge the notion that simulators could not be made fast enough to run large workloads, nor accurate enough to run commercial operating systems. His innovations in simulator design culminated in Simics, the first academic simulator that could boot and run commercial multiprocessor workloads. Simics saw huge academic success and has been used to run simulations for research presented in several hundred subsequent publications.

Peter founded Virtutech in 1998 to commercially develop Simics, and he ultimately forged and became the leader in a new market segment for software tools. With Peter at the helm, Virtutech pushed Simics beyond several performance barriers to make it the first simulator to exceed 1 billion instructions per second and the first simulator to model over 1,000 processors. Peter joined Google in 2010 to work with cloud computing.


Dr. Amin Vahdat, Principal Engineer

For contributions to data center scalability and management

Amin’s work made an impact at Google long before he arrived here. Amin is known for conducting research through bold, visionary projects that combine creativity with careful consideration of the engineering constraints needed to make them applicable in real world applications. Amin’s infrastructure ideas have underpinned the shift in the computing field from the pure client-server paradigm to a landscape in which major web services are hosted “in the cloud” across multiple data centers. In addition to pioneering “third-party cloud computing” through his work on WebOS and Rent-A-Server in the mid-90s, Amin has made important advancements in managing wide-area consistency between data centers, scalable modeling of data center applications, and building scalable data center networks.

Amin’s innovations have penetrated and broadly influenced the networking community within academia and industry, including Google, and his research has been recapitulated and expanded upon in a number of publications. Conferences that formerly did not even cover data centers now have multiple sessions covering variants of what Amin and his team have proposed. At Google, Amin continues to drive next-generation data center infrastructure focusing on Software Defined Networking and new opportunities from optical technologies. This is emblematic of Amin’s ability to build real systems, and perhaps more significantly, convince people of their value.

Four Googlers elected ACM Fellows this year

Posted by Alfred Spector, VP of Research

I am delighted to share with you that, like last year, the Association for Computing Machinery (ACM) has announced that four Googlers have been elected ACM Fellows in 2010, the most this year from any single corporation or institution.

Luiz Barroso, Dick Lyon, Muthu Muthukrishnan and Fernando Pereira were chosen for their contributions to computing and computer science that have provided fundamental knowledge to the field and have generated multiple innovations.

On behalf of Google, I congratulate our colleagues, who join the 10 other ACM Fellows and other professional society awardees at Google in exemplifying our extraordinarily talented people. I’ve been struck by the breadth and depth of their contributions, and I hope that they will serve as inspiration for students and computer scientists around the world.

You can read more detailed summaries of their achievements below, including the official citations from ACM—although it’s really hard to capture everything they’ve accomplished in one paragraph!

Dr. Luiz Barroso: Distinguished Engineer
For contributions to multi-core computing, warehouse scale data-center architectures, and energy proportional computing

Over the past decade, Luiz has played a leading role in the definition and implementation of Google’s cluster architecture which has become a blueprint for the computing systems behind the world’s leading Internet services. As the first manager of Google’s Platforms Engineering team, he helped deliver multiple generations of cluster systems, including the world’s first container-based data center. His theoretical and engineering insights into the requirements of this class of machinery have influenced the processor industry roadmap towards more effective products for server-class computing. His book "The Datacenter as a Computer" (co-authored with Urs Hoelzle) was the first authoritative publication describing these so-called warehouse-scale computers for computer systems professionals and researchers. Luiz was among the first computer scientists to recognize and articulate the importance of energy-related costs for large data centers, and identify energy proportionality as a key property of energy efficient data centers. Prior to Google, at Digital Equipment's Western Research Lab, he worked on Piranha, a pioneering chip-multiprocessing architecture that inspired today’s popular multi-core products. As one of the lead architects and designers of Piranha, his papers, ideas and numerous presentations stimulated much of the research that led to products decades later.

Richard Lyon: Research Scientist
For contributions to machine perception and for the invention of the optical mouse

In the last four years at Google, Dick led the team developing new camera systems and improved photographic image processing for Street View, while leading another team developing technologies for machine hearing and their application to sound retrieval and ranking. He is now writing a book with Cambridge University Press, and will teach a Stanford course this fall on "Human and Machine Hearing," returning to a line of work that he carried out at Xerox, Schlumberger, and Apple while also doing the optical mouse, bit-serial VLSI computing machines, and handwriting recognition. The optical mouse (1980) is especially called out in the citation, because it exemplifies the field of "semi-digital" techniques that he developed, which also led to his work on the first single-chip Ethernet device. And more recently, as chief scientist at Foveon, Dick invented and developed several new techniques for color image sensing and processing, and delivered acclaimed cameras and end-user software. A hallmark of Dick’s work during his distinguished career has been a practical interplay between theory, including biological theory, and practical computing.

Dr. S. Muthukrishnan: Research Scientist
For contributions to efficient algorithms for string matching, data streams, and Internet ad auctions

Muthu has made significant contributions to the theory and practice of Internet ad systems during his more than four years at Google. Muthu's breakthrough WWW’09 paper presented a general stable matching framework that produces a (desirable) truthful mechanism capturing all of the common variations and more, in contradiction to prevailing wisdom. In display ads, where image, video and other types of ads are shown as users browse, Muthu led Ad Exchange at Google, to automate placement of display ads that were previously negotiated offline by sales teams. Prior to Google, Muthu was well known for his pioneering work in the area of data stream algorithmics (including a definitive book on the subject), which led to theoretical and practical advances still in use today to monitor the health and smooth operation of the Internet. Muthu has a talent for bringing new perspectives to longstanding open problems as exemplified in the work he did on string processing. Muthu has made influential contributions to many other areas and problems including IP networks, data compression, scheduling, computational biology, distributed algorithms and database technology. As an educator, Muthu’s avant garde teaching style won him the Award for Excellence in Graduate Teaching at Rutgers CS, where is on the faculty. As a student remarked in his blog: "there is a magic in his class which kinda spellbinds you and it doesn't feel like a class. It’s more like a family sitting down for dinner to discuss some real world problems. It was always like that even when we were 40 people jammed in for cs-513."

Dr. Fernando Pereira: Research Director
For contributions to machine-learning models of natural language and biological sequences

For the past three years, Fernando has been leading some of Google’s most advanced natural language understanding efforts and some of the most important applications of machine learning technology. He has just the right mix of forward thinking ideas and the ability to put ideas into practice. With this balance, Fernando has has helped his team of research scientists apply their ideas at the scale needed for Google. From when he wrote the first Prolog compiler (for the PDP-10 with David Warren) to his days as Chair at University of Pennsylvania, Fernando has demonstrated a unique understanding of the challenges and opportunities that faced companies like Google with their unprecedented access to massive data sets and its application to the world of speech recognition, natural language processing and machine translation. At SRI, he pioneered probabilistic language models at a time when logic-based models were more popular. At AT&T, his work on a toolkit for finite-state models became an industry standard, both as a useful piece of software and in setting the direction for building ever larger language models. And his year at WhizBang had an influence on other leaders of the field, such as Andrew McCallum at University of Massachusetts and John Lafferty and Tom Mitchell at Carnegie Mellon University, with whom Fernando developed the Conditional Random Field model for sequence processing that has become one of the leading tools of the trade.

Finally, we also congratulate Professor Christos Faloutsos of Carnegie Mellon, who is on sabbatical and a Visiting Faculty Member at Google this academic year. Professor Faloutsos is cited for contributions to data mining, indexing, fractals and power laws.
