Phil Gibbons Named Recipient of 2019 Paris Kanellakis Theory and Practice Award

The Paris Kanellakis Theory and Practice Award honors specific theoretical accomplishments that have had a significant and demonstrable effect on the practice of computing. ThIs award is accompanied by a prize of $10,000 and is endowed by contributions from the Kanellakis family, with additional financial support provided by ACM's Special Interest Groups on Algorithms and Computational Theory (SIGACT), Design Automaton (SIGDA), Management of Data (SIGMOD), and Programming Languages (SIGPLAN), the ACM SIG Projects Fund, and individual contributions.

ACM has named Noga Alon of Princeton University and Tel Aviv University; Phillip Gibbons of Carnegie Mellon University; Yossi Matias of Google and Tel Aviv University; and Mario Szegedy of Rutgers University recipients of the ACM Paris Kanellakis Theory and Practice Award for seminal work on the foundations of streaming algorithms and their application to large-scale data analytics.

Alon, Gibbons, Matias and Szegedy pioneered a framework for algorithmic treatment of streaming massive datasets. Today, their sketching and streaming algorithms remain the core approach for streaming big data and constitute an entire subarea of the field of algorithms. Additionally, the concepts of sketches and synopses that they introduced are now routinely used in a variety of data analysis tasks in databases, network monitoring, usage analytics in internet products, natural language processing and machine learning.

In their seminal paper, “The Space Complexity of Approximating the Frequency Moments,” Alon, Matias and Szegedy laid the foundations of the analysis of data streams using limited memory. Follow-up papers, including “Tracking Join and Self-join Sizes in Limited Storage,” by Alon, Gibbons, Matias, and Szegedy, and “New Sampling-Based Summary Statistics for Improving Approximate Query Answers,” by Gibbons and Matias, expanded on the idea of data synopses and were instrumental n the development of the burgeoning fields of streaming and sketching algorithms. This work has been applied to query planning and processing in databases and the design of small synopses to monitor vast quantities of data generated in networks.

M. Satyanarayanan Named A University Professor

Seven Carnegie Mellon University faculty members have been elevated to the rank of University Professor, the highest distinction a faculty member can achieve at CMU. Among the newly appointed University Professors is Mahadev Satyanarayanan, a faculty member of the Parallel Data Lab.

"University Professors are distinguished by international recognition and for their contributions to education, artistic creativity and/or research," said Provost Jim Garrett. "Each University Professor exemplifies a high level of professional achievement and an exceptional commitment to academic excellence at our university." Garrett said professors are nominated and recommended by academic leaders and faculty who have already achieved the designation of University Professor.

Mahadev Satyanarayanan, best known as Satya, is the Carnegie Group Professor of Computer Science. He is an experimental computer scientist, who designs, implements and evaluates systems. Satya's multi-decade research career has focused on the challenges of performance, scalability, availability and trust in information systems that reach from the cloud to the mobile edge of the Internet.

In the course of this work, he has pioneered many advances in distributed systems, mobile computing, pervasive computing, and the Internet of Things (IoT). Examples include his work as principal architect of CMU's pioneering Andrew File System in the 1980s, his work on disconnected and weakly connected mobile data access in the Coda File System in the early 1990s, his work on adaptive and energy-efficient mobile computing in the Odyssey system in the late 1990s and early 2000s and his most recent work in establishing the field of edge computing.

Satya directs the Living Edge Laboratory, which explores edge computing in live settings. By introducing a new computing tier between the cloud and mobile/IoT devices, edge computing makes powerful computational resources available via low latency and high bandwidth wireless networks. Another project, called Gabriel, leverages edge computing to amplify human cognition in real time for complex task guidance. Low latency wireless access to resources that are larger, heavier and more energy hungry than could ever be carried or worn by a human user is crucial to realizing this vision.

Satya earned his Ph.D. in computer science at CMU in 1983. An Association for Computing Machinery (ACM) and IEEE Fellow, he is the recipient of numerous awards, including the Association for Computing Machinery's prestigious Software System Award for his work on the Andrew File System.

Scaling Up Metadata

Creating and managing massive numbers of records has turned out to be a long-standing challenge for computer file-system researchers. Handling millions or billions of files is extremely difficult, let alone trillions.

But that’s what a team of researchers from Los Alamos National Laboratory (LANL) and Carnegie Mellon University is doing, satisfying a demand for managing truly huge quantities of files. Their solution, DeltaFS, is a distributed file system for high-performance computing (HPC) that’s distributed via GitHub. [...read more]

Rashmi Vinayak Wins NSF CAREER Award

Rashmi Vinayak, an assistant professor in the Carnegie Mellon University Computer Science Department, has won a five-year, $650,000 Faculty Early Career Development (CAREER) Award, the National Science Foundation's most prestigious award for young faculty members.

The award will support Vinayak's work to improve the resource and energy efficiency of large-scale data centers, which together serve as the backbone for internet-based services, cloud services and data analytics platforms.

"Such large-scale systems are prone to failures and unavailability, and therefore have a high degree of redundancy built in to them to provide resilience against such events," she noted. "While redundancy provides resilience, it comes with a significant overhead in terms of resource and energy requirements. The overarching goal of this project is to design resource- and energy-efficient redundancy algorithms for data centers using tools based on information theory and coding theory."

Vinayak earned her Ph.D. in electrical engineering and computer science at the University of California at Berkeley, where she also worked as a postdoctoral researcher before joining CSD in 2017. Her previous awards include the Eli Jury Award from Berkeley's EECS Department, a Google Faculty Research Award, Facebook Communications and Networking Research Award, and the Tata Institute of Fundamental Research Memorial Lecture Award.
