CONTENTS

New book, Vector Extrapolation Methods with Applications

Announcing the publication by SIAM of:

Vector Extrapolation Methods with Applications
Avram Sidi
Computational Science and Engineering 17

An important problem that arises in different disciplines of science and engineering is that of computing limits of sequences of vectors of very large dimension. Such sequences arise, for example, in the numerical solution of systems of linear and nonlinear equations by fixed-point iterative methods, and their limits are simply the required solutions to these systems. The convergence of these sequences, which is very slow in many cases, can be accelerated successfully by using suitable vector extrapolation methods.

Vector Extrapolation Methods with Applications is the first book fully dedicated to the subject of vector extrapolation methods. It is a self-contained, up-to-date, and state-of-the-art reference on the theory and practice of the most useful methods. It covers all aspects of the subject, including development of the methods, their convergence study, numerically stable algorithms for their implementation, and their various applications. It also provides complete proofs in most places. As an interesting application, the author shows how these methods give rise to rational approximation procedures for vector-valued functions in the complex plane, a subject of importance in model reduction problems among others.

Audience
This book is intended for numerical analysts, applied mathematicians, and computational scientists and engineers in fields such as computational fluid dynamics, structures, and mechanical and electrical engineering, to name a few. Since it provides complete proofs in most places, it can also serve as a textbook in courses on acceleration of convergence of iterative vector processes, for example.

About the Author
Avram Sidi is Professor Emeritus of Numerical Analysis in the Computer Science Department at the Technion-Israel Institute of Technology and the former holder of the Technion Administration Chair in Computer Science. He has published extensively in various areas of numerical analysis and approximation theory, such as convergence acceleration, numerical integration, rational approximation, and asymptotic analysis, convergence acceleration being a major area. He is also the author of the book Practical Extrapolation Methods: Theory and Applications (Cambridge University Press, 2003), which deals exclusively with the acceleration of convergence of scalar sequences. His research has involved the development of novel numerical methods of high accuracy, their rigorous mathematical analysis, design of efficient algorithms for their implementation, and their application to difficult problems. His methods and algorithms are being used successfully in various scientific and engineering disciplines.

ACM PASC18, Basel, July 02-04, 2018: First Call for Papers, Minisymposia and Posters Submissions

The Platform for Advanced Scientific Computing (PASC) is pleased to announce that submissions will open on October 25 for the PASC18 Conference, co-sponsored by the Association for Computing Machinery (ACM). Submissions are invited for papers, minisymposia and poster presentations. PASC18 will be held from July 02 to 04, 2018, at the Congress Center Basel, Switzerland (https://pasc18.pasc-conference.org)

The PASC18 Organizing Team is pleased to announce that submissions are now open for minisymposium, paper and poster contributions. We look forward to receiving your submissions through the online submission portal (https://pasc18.pasc-conference.org/submission/submissions-portal/). Please note that the November 26th deadline for minisymposia proposals is rapidly approaching!

CONFERENCE

PASC18 is the fifth edition of the PASC Conference series, an international platform for the exchange of competences in scientific computing and computational science, with a strong focus on methods, tools, algorithms, application challenges, and novel techniques and usage of high performance computing. The theme of PASC18 is Fast and Big Data, Fast and Big Computation, emphasizing our vision of the close coupling of data and computation. Exposing and expressing massive and irregular parallelism in computational problems are key challenges for exploiting the massive and heterogeneous parallelism available in current, and expected in future, HPC systems, as well as to find new ways of generating scientific insight from data and models. Through its rich and interactive program, PASC18 aims to highlight the computational approaches that computational scientists, computer scientists, and practitioners employ today and will employ over the next decades to address these challenges.

CONTRIBUTIONS

PASC18 welcomes submissions for minisymposium, paper, and poster contributions that demonstrate innovative research in scientific computing related to the following scientific domains:

  • Chemistry and Materials
  • Life Sciences
  • Physics
  • Climate and Weather
  • Solid Earth Dynamics
  • Engineering
  • Computer Science and Applied Mathematics
  • Emerging Applications Domains (e.g. Social Sciences, Finance,…)

Upcoming Submission Deadlines

  • Minisymposia: November 26, 2017
  • Papers: January 19, 2018
  • Posters: February 4, 2018

MINISYMPOSIA

A minisymposium at PASC18 is a two-hour session of four presentations on a topic of current importance in computational science that showcases research related to domain science, applied mathematics, computer science or software engineering. Proposals should describe research that is of significant current interest to a given PASC scientific domain, and ideally, have potential application to additional domains. Proposals should include speakers from multiple institutions and/or countries, and be designed such that the speakers bring a range of different perspectives to the topic. PASC18 encourages gender balance and diversity.

PAPERS

The goal of the PASC papers program is to advance the quality of interdisciplinary exchange between the various specific fields of computational science and engineering. We welcome high-quality contributions of original research related to scientific computing in any of the eight PASC scientific domains. Papers will be evaluated by domain experts primarily on their significance, technical soundness, originality, and quality of communication. Papers accepted for PASC18 will be presented as talks, and published in the Proceedings of the PASC Conference, accessible via the ACM Digital Library. A selection of the highest quality papers may be given the opportunity of a plenary presentation. In selecting papers for plenary presentation, the Scientific Reviewing Committee will place particular weight on impact, interdisciplinarity and interest to a broad audience. Following the conference, authors will have the opportunity to further develop their PASC papers for publication in a relevant, computationally focused, domain-specific journal. Authors thus stand to benefit from the rapid and broad dissemination of results afforded by the conference venue and associated published proceedings, as well as the impact associated with publication in a high-quality scientific journal.

POSTERS

Poster presentations provide an ideal opportunity for the exchange of ideas and expertise within and between the various computational science domains represented at the conference. Poster submissions should describe topical research related to domain science, applied mathematics, computer science or software engineering. Poster presenters will be given the possibility to “pitch” their posters to the conference audience in a rapid-fire flash session, and posters with the most stimulating content will be recognized in an award ceremony on the final day of the conference.
