SIGOPS Annual Report 2012
SIGOPS Annual Report 2012 Fiscal Year July 2012-June 2013 Submitted by Jeanna Matthews, SIGOPS Chair Overview SIGOPS is a vibrant community of people with interests in “operatinG systems” in the broadest sense, includinG topics such as distributed computing, storaGe systems, security, concurrency, middleware, mobility, virtualization, networkinG, cloud computinG, datacenter software, and Internet services. We sponsor a number of top conferences, provide travel Grants to students, present yearly awards, disseminate information to members electronically, and collaborate with other SIGs on important programs for computing professionals. Officers It was the second year for officers: Jeanna Matthews (Clarkson University) as Chair, GeorGe Candea (EPFL) as Vice Chair, Dilma da Silva (Qualcomm) as Treasurer and Muli Ben-Yehuda (Technion) as Information Director. As has been typical, elected officers agreed to continue for a second and final two- year term beginning July 2013. Shan Lu (University of Wisconsin) will replace Muli Ben-Yehuda as Information Director as of AuGust 2013. Awards We have an excitinG new award to announce – the SIGOPS Dennis M. Ritchie Doctoral Dissertation Award. SIGOPS has lonG been lackinG a doctoral dissertation award, such as those offered by SIGCOMM, Eurosys, SIGPLAN, and SIGMOD. This new award fills this Gap and also honors the contributions to computer science that Dennis Ritchie made durinG his life. With this award, ACM SIGOPS will encouraGe the creativity that Ritchie embodied and provide a reminder of Ritchie's leGacy and what a difference a person can make in the field of software systems research. The award is funded by AT&T Research and Alcatel-Lucent Bell Labs, companies that both have a strong connection to AT&T Bell Laboratories where Dennis Ritchie did his seminal work. -
2020 SIGACT REPORT SIGACT EC – Eric Allender, Shuchi Chawla, Nicole Immorlica, Samir Khuller (Chair), Bobby Kleinberg September 14Th, 2020
2020 SIGACT REPORT SIGACT EC – Eric Allender, Shuchi Chawla, Nicole Immorlica, Samir Khuller (chair), Bobby Kleinberg September 14th, 2020 SIGACT Mission Statement: The primary mission of ACM SIGACT (Association for Computing Machinery Special Interest Group on Algorithms and Computation Theory) is to foster and promote the discovery and dissemination of high quality research in the domain of theoretical computer science. The field of theoretical computer science is the rigorous study of all computational phenomena - natural, artificial or man-made. This includes the diverse areas of algorithms, data structures, complexity theory, distributed computation, parallel computation, VLSI, machine learning, computational biology, computational geometry, information theory, cryptography, quantum computation, computational number theory and algebra, program semantics and verification, automata theory, and the study of randomness. Work in this field is often distinguished by its emphasis on mathematical technique and rigor. 1. Awards ▪ 2020 Gödel Prize: This was awarded to Robin A. Moser and Gábor Tardos for their paper “A constructive proof of the general Lovász Local Lemma”, Journal of the ACM, Vol 57 (2), 2010. The Lovász Local Lemma (LLL) is a fundamental tool of the probabilistic method. It enables one to show the existence of certain objects even though they occur with exponentially small probability. The original proof was not algorithmic, and subsequent algorithmic versions had significant losses in parameters. This paper provides a simple, powerful algorithmic paradigm that converts almost all known applications of the LLL into randomized algorithms matching the bounds of the existence proof. The paper further gives a derandomized algorithm, a parallel algorithm, and an extension to the “lopsided” LLL. -

Valiant of Harvard University the winner of the 2010 ACM A.M. Turing Award http://www.acm.org/news/featured/turing-award-2010 for his fundamental contributions to the development of computational learning theory and to the broader theory of computer science. Valiant brought together machine learning and computational complexity, leading to advances in artificial intelligence as well as computing practices such as natural language processing, handwriting recognition, and computer vision. He also launched several subfields of theoretical computer science, and developed models for parallel computing. The Turing Award, widely considered the “Nobel Prize in Computing", is named for the British mathematician Alan M. Turing. The award carries a $250,000 prize, with financial support provided by Intel Corporation and Google Inc. “Leslie Valiant’s accomplishments over the last 30 years have provided the theoretical basis for progress in artificial intelligence and led to extraordinary achievements in machine learning. His work has produced modeling that offers computationally inspired -

Erica Flapan, Notices Editor in Chief I would like to introduce myself as the new Editor in Chief of the Notices and share my plans with readers. The Notices is an interesting and engaging magazine that is read by mathematicians all over the world. As members of the AMS, we should all be proud to have the Notices as our magazine of record. Personally, I have enjoyed reading the Notices for over 30 years, and I appreciate the opportunity that the AMS has given me to shape the magazine for the next three years. I hope that under my leadership even more people will look forward to reading it each month as much as I do. Above all, I would like the focus of the Notices to be on expository articles about pure and applied mathematics broadly defined. I would like the authors, topics, and writing styles of these articles to be diverse in every sense except for their desire to explain the mathematics that they love in a clear and engaging way. -
