Register now for the 2020 Turing Lecture, “Abstractions, Their Algorithms, and Their Compilers,” presented on Thursday, July 22 at 12:00 PM ET/9:00 AM PT by the recipients of the 2020 ACM A.M. Turing Award: Alfred Aho, Lawrence Gussman Professor Emeritus of Computer Science at Columbia University, and Jeffrey Ullman, Stanford W. Ascherman Professor of Engineering (Emeritus) in the Department of Computer Science at Stanford University. 2017 ACM A.M. Turing Award laureate John L. Hennessy, James F. and Mary Lynn Gibbons Professor of Computer Science and Electrical Engineering in the Stanford School of Engineering, will moderate the questions and answers session following the talk.
(The talk will be recorded and will be made available on demand for anyone who registers.)
Computational thinking is an essential skill in the information age. We will talk about the core of computational thinking: abstractions and their uses. We begin with a taxonomy of abstractions based on their intended purpose and identify four different kinds of abstractions that are commonly used in computing. We look at three areas of computer science in which abstractions play a vital role. Compiler design is one of the first areas of computer science where powerful abstractions led to important improvements in the technology. More recently, the need to deal with increasingly large datasets has led to the development of new abstractions and increased the importance of old ones. Finally, we examine an abstraction that supports quantum computation and its potential for new computing capabilities. We close with some problems regarding computing abstractions that may lead to advances in the future.
Duration: 75 minutes (including audience Q&A)
Presenter:
Alfred Aho, Columbia University
Alfred V. Aho is the Lawrence Gussman Professor Emeritus of Computer Science at Columbia University. Aho is well known for his many papers and books on algorithms and data structures, programming languages, compilers, and the foundations of computer science. His research interests have included programming languages, compilers, algorithms, software engineering, and quantum computation. He’s a recipient of the ACM A. M. Turing Award and the IEEE John von Neumann Medal. Aho is a Member of the U.S. National Academy of Engineering and of the American Academy of Arts and Sciences. He is a Fellow of the American Association for the Advancement of Science, ACM, Bell Labs, IEEE, and the Royal Society of Canada. Aho has served as Vice President of the Computing Sciences Research Center at Bell Labs, the lab that invented UNIX, C, and C++. Professor Aho also served as General Manager of the Information Sciences and Technologies Research Laboratory at Bellcore (Telcordia).
Presenter:
Jeffrey Ullman, Stanford University
Jeffrey Ullman is the Stanford W. Ascherman Professor of Engineering (Emeritus) in the Department of Computer Science at Stanford University and CEO of Gradiance Corp. Prior to his appointment at Stanford, he was a member of the technical staff of Bell Laboratories, and on the faculty of Princeton University between. He later served as chair of the Stanford Computer Science Department. Ullman was elected to the National Academy of Engineering, the American Academy of Arts and Sciences, the National Academy of Sciences, and has held Guggenheim and Einstein Fellowships. He has received the SIGMOD Contributions Award, the ACM Karl V. Karlstrom Outstanding Educator Award, the Knuth Prize, the SIGMOD E. F. Codd Innovations Award, the IEEE von Neumann Medal, the NEC C&C Foundation Prize, and the ACM A.M. Turing Award. He is the author of 16 books, including books on database systems, data mining, compilers, automata theory, and algorithms.
Moderator:
John L. Hennessy, Stanford University
John L. Hennessy is the James F. and Mary Lynn Gibbons Professor of Computer Science and Electrical Engineering in the Stanford School of Engineering, and the Shriram Family Director of Stanford’s Knight-Hennessy Scholars, the largest fully endowed graduate-level scholarship program in the world. He is chairman of Alphabet and serves as a trustee of the Gordon and Betty Moore Foundation. Formerly the tenth president of Stanford, he is also a computer scientist who co-founded MIPS Computer Systems and Atheros Communications. John is the coauthor (with David Patterson) of two internationally used textbooks in computer architecture. His honors include the Medal of Honor of the Institute of Electrical and Electronics Engineers, the ACM A.M. Turing Award (jointly with David Patterson), and the BBVA Foundation Frontiers of Knowledge Award (jointly with David Patterson).
