Most of these were due to issues associated with aging systems supporting the NA Digest to this point, and we are fortunate to have been able to migrate to a more stable, long-term solution. Please continue to submit new announcements using the submission form located at: http://icl.cs.utk.edu/na-digest/websubmit.html As we continue to improve the NA Digest throughout this new year, please feel free to send comments and suggestions to me at [log in to unmask] Best regards, Danny Dunlavy NA Digest Editor ------------------------------------------------------- From: Jon Lee [log in to unmask] Date: December 19, 2013 Subject: Free book on linear optimization Announcing a free and open-source book on Linear Optimization. Jon Lee, "A First Course in Linear Optimization", First Edition, Reex Press, 2013. The book together with associated Matlab/AMPL/Mathematica programs are freely available from: https://sites.google.com/site/jonleewebpage/home/publications/#book ------------------------------------------------------- From: Klaus Iglberger [log in to unmask] Date: January 05, 2014 Subject: Blaze 1.5 Released Version 1.5 of the Blaze library, one of the fastest high-performance C++ math libraries, has been released. This release is all about performance. Just like all C++ libraries using expression templates Blaze is heavily depending on the compiler's ability to optimize the given template code. Unfortunately several compilers were not able to achieve maximum performance for many operations. In Blaze 1.5 we have focused on resolving the underlying problem and made it easier for the compiler to perform the necessary optimizations. Get an impression of the improved performance in the updated Benchmarks section: http://code.google.com/p/blaze-lib/wiki/Benchmarks Blaze 1.5 is now available for download at http://code.google.com/p/blaze-lib. ------------------------------------------------------- From: Timo Heister [log in to unmask] Date: January 03, 2014 Subject: Finite element software deal.II version 8.1 released Version 8.1 of deal.II, the object-oriented finite element library awarded the J. H. Wilkinson Prize for Numerical Software, has been released. It is available for free under an Open Source license from the deal.II homepage at http://www.dealii.org/ This version is primarily a maintenance release but still has a number of noteworthy new features: - Three new tutorial programs on elasto-plastic contact problems (step-42), hybridizable dicontinuous Galerkin methods (step-51), and a simple example of using adaptive mesh refinement for time dependent problems (step-26) - Significantly better support for shared memory multicore parallelism - Dozens of new features and bugfixes For more information see http://arxiv.org/abs/1312.2266v4 Wolfgang Bangerth, Timo Heister, Guido Kanschat, and many other contributors. ------------------------------------------------------- From: Damon McDougall [log in to unmask] Date: January 06, 2014 Subject: QUESO: A C++ library for uncertainty quantification QUESO stands for Quantification of Uncertainty in Estimation, Simulation and Optimisation. QUESO is a collection of algorithms and other functionalities aimed at solving statistical inverse problems, solving statistical forward problems, validating models, and for the prediction of quantities of interest from such models along with the quantification of their uncertainties. QUESO is designed for flexibility, portability, ease of use and ease of extension. Its software design follows an object-oriented approach and is written in C++. QUESO uses MPI for communication. It can run in uniprocessor or multiprocessor environments. QUESO v0.50.0 was released recently and is free (libre and speech).

Besides optimal implementation strategies, novel mathematical concepts are needed to fully exploit massively parallel architectures. For the numerical solution of time-dependent partial differential equations, time-parallel methods have recently shown to provide a promising way to extend prevailing strong-scaling limits of numerical codes. This workshop will bring together scientists from the fields of multigrid methods and parallel- in-time integration in order to discuss similarities between parallel multilevel algorithms in space and time, their applications and their combination. Invited Speakers: * Martin Gander - Université de Genève, Switzerland * Matthew Emmett - Lawrence Berkeley National Laboratory, USA * Scott MacLachlan, Tufts University, USA * Cornelius Oosterlee, TU Delft, The Netherlands Contact: Robert Speck, +49 2461 611644, [log in to unmask] Registration and call for participation will open in late January 2014.
