Prof. Woongki Baek wins Most Influential PLDI Paper Award

Professor Woongki Baek in the department of Computer Science and Engineering at UNIST has been selected as a recipient of Most Influential PLDI Paper Award at PLDI 2020 for his research paper entitled “Green: A Framework for Supporting Energy-Conscious Programming using Controlled Approximation”, which was published in PLDI 2010. PLDI (ACM SIGPLAN Conference on Programming Language Design and Implementation) is the top conference in the field of programming languages and compilers.

The selection committee for Most Influential PLDI Paper Award says “Most Influential PLDI Paper Award is presented annually to the author(s) of a paper presented at the PLDI held 10 years prior to the award year. The papers are judged by their influence over the past decade.” In addition, the selection committee cites the paper as follows.

“The PLDI paper “Green: A Framework for Supporting Energy-Conscious Programming using Controlled Approximation” by Woongki Baek and Trishul Chilimbi demonstrated conclusively two important things:  (1) that frameworks supporting approximations that trade energy/performance costs for quality of service could be generalized and automated, and (2) applying this approach in data center search workloads could result in significant energy reduction and cost, saving millions of dollars in practice. Green proved that systematic approaches to approximate computing could have enormous commercial impact and predated and informed many subsequent machine learning optimizations, such as using reduced precision arithmetic in deep learning models. Green also inspired subsequent efforts, to more deeply encode approximation semantics into the underlying programming language design.”
