My new address is: Tim Davis Dept of Computer Science and Engineering 3112 TAMU College Station TX 77843-3112 http://engineering.tamu.edu/cse/people/davis-tim email: [log in to unmask] office: (979) 845-4094 My software repository is still hosted at the University of Florida, as is the University of Florida Sparse Matrix Collection, at http://www.cise.ufl.edu/research/sparse. I will post an update when I move the collection and my software to Texas A&M. I'm also looking for a postdoc or two, funded by Texas A&M. The position was posted earlier in the NA Digest: http://www.netlib.org/na-digest-html/14/v14n15.html#5 I've received several excellent applications but I'm still considering additional candidates. I'm looking for PhD students as well. The postdocs and PhD students will be working with me in my lab here at Texas A&M, recently designated by NVIDIA as a CUDA Research Center, in support of my work in GPU / many-core algorithms. ------------------------------------------------------- From: Robert van de Geijn [log in to unmask] Date: June 16, 2014 Subject: Notes for MOOC on Introductory Linear Algebra During Spring 2014, we offered a Massive Open Online Course (MOOC) titled "Linear Algebra: Foundations to Frontiers (LAFF)". With this course, we attempt to appeal to computation oriented audiences by linking abstractions in the mathematics (e.g., viewing matrices by rows or columns) with abstractions in algorithms and implementations (partitioning of arrays into rows, columns, and blocks). For the NADigest audience, this can be described as "from the start, the layering in the mathematics is linked to the layering in the BLAS and LAPACK". We now make the materials that were created for this course available. At the core is a 900 page document that includes homework with detailed solutions, links to more than 250 short videos, and programming activities in Python, using IPython Notebooks. Given feedback from participants in the MOOC, we have concluded that these materials are valuable to a broad audience that includes beginning students who have not had a previous exposure to linear algebra but also professionals with advanced degrees who want to review the foundations of linear algebra. Beginning graduate students can use the notes to learn how to think in terms of partitioned matrices and how performance relates to architecture (an enhancement activity in the course) in preparation for a graduate level course in numerical linear algebra. Educators may wish to use the notes in a "flipped classroom" setting.

The focus of this newest release is the improvement and extension of the shared memory parallelization capabilities. And this gives you some new exiting features: In addition to the OpenMP parallelization, Blaze 2.1 now also enables shared memory parallelization based on C++11 and Boost threads. With that, shared memory parallel execution is now available for virtually every platform and compiler. Additionally, the underlying architecture for the parallel execution and automatic, context-depending optimization has been significantly improved. This not only improves the performance and determinism of the parallelizations, but also for instance enables an efficient parallel handling of computations involving block structured vectors and matrices. Therefore Blaze 2.1 should prove to be the fastest and most flexible Blaze release yet. ------------------------------------------------------- From: Nick Hale [log in to unmask] Date: June 21, 2014 Subject: CHEBFUN Version 5 Release We are pleased to announce the release of Chebfun Version 5, available for download at http://www.chebfun.org/download/ Version 5 has involved a complete rewrite of the code with a focus on clarity to make it more accessible and extensible. The code is hosted on GitHub (https://github.com/chebfun/), and we welcome new developers to get involved. Chebfun is an open-source software system for numerical computing with functions. The mathematical basis is piecewise polynomial interpolation implemented with what we call “Chebyshev technology”. The foundations are described, with Chebfun examples, in the book Approximation Theory and Approximation Practice (L. N. Trefethen, SIAM 2013). Chebfun has extensive capabilities for dealing with linear and nonlinear differential and integral operators, and also includes continuous analogues of linear algebra notions like QR and singular value decomposition. The Chebfun2 extension works with functions of two variables defined on a rectangle in the x-y plane. To get a sense of the breadth and power of Chebfun, a good place to start is by looking at our Examples at http://www.chebfun.org/examples/ or the introductory Guide at http://www.chebfun.org/docs/guide/ New features in V5 include: - First official release of Chebfun2 for bivariate computing - Powerful new bivariate rootfinding algorithms - Major speedups of conv, polyfit, abs, inv, and pde15s - O(nlogn) codes leg2cheb, cheb2leg for coefficient conversion - Option for algorithms based on first kind Chebyshev points - A Chebfun constructor option 'equi' for equispaced data - A 'periodic' flag for Fourier interpolants instead of Chebyshev - Ultraspherical spectral methods for ODEs - Improved graphical interface (chebgui) for ODE capabilities Please contact us with any questions/comments at [log in to unmask] ------------------------------------------------------- From: Joseph Young [log in to unmask] Date: June 20, 2014 Subject: Release of Optizelle 1.1.2 for nonlinear optimization Optizelle [op-tuh-zel] is an open source software library designed to solve general purpose nonlinear optimization problems. http://www.optimojoe.com/products/optizelle Optizelle features - State of the art algorithms - Unconstrained -- steepest descent, preconditioned nonlinear-CG, BFGS, Newton-CG, SR1, trust-region Newton (truncated-CG and truncated-MINRES), Barzilai-Borwein two-point approximation - Equality constrained -- inexact composite-step SQP - Inequality constrained -- primal-dual interior point method for cone constraints (linear, second-order cone, and semidefinite), log-barrier method for cone constraints - Constrained -- any combination of the above - Open source - Released under the 2-Clause BSD License - Free and ready to use with both open and closed sourced codes - Multilanguage support - Interfaces to C++, MATLAB/Octave, and Python - Robust computations and repeatability - Can stop, archive, and restart the computation from any optimization iteration - User-defined parallelism - Fully compatible with OpenMP, MPI, or GPUs ------------------------------------------------------- From: Martin Peters [log in to unmask] Date: June 17, 2014 Subject: New Book Edition, Scientific Computing with MATLAB and Octave The new (fourth) edition of TCSE 2 Quarteroni/Saleri/Gervasio - Scientific Computing with MATLAB and Octave has now been published - ISBN 978-3-642-45366-3.

This often hinders the development of their research and, consequently, their ongoing professional career. For this reason, young researchers decided to create an appropriate framework to share research results, thus giving rise to 'I Brazilian Congress of Young Researchers in Pure and Applied Mathematics'. Thematic Sessions: Algebra, Functional Analysis, Numerical Analysis, 'Set Theory, Topology and Banach Spaces', Biomathematics, Partial Differential Equations, Mathematical Physics, Geometry, Discrete Mathematics, Probability and Statistics, Optimization, Operations Research, Orthogonal Polynomials, Singularities and Foliations, Dinamical Systems Website: http://jovens.ime.usp.br Date: December, 10-12 2014 The event will take place at the Institute of Mathematics and Statistics, University of Sao Paulo, Sao Paulo, Brazil. ------------------------------------------------------- From: Phan Thanh An [log in to unmask] Date: June 18, 2014 Subject: High Performance Scientific Computing, Vietnam, Mar 2015 6TH INTERNATIONAL CONFERENCE ON HIGH PERFORMANCE SCIENTIFIC COMPUTING Modeling, Simulation and Optimization of Complex Processes March 16-20, 2015, Hanoi, Vietnam Topics: - mathematical modeling - numerical simulation - methods for optimization and control - parallel computing: architectures, algorithms, tools and environments - software development - applications of scientific computing in physics, mechanics, hydrology, chemistry, biology, medicine, transport, logistics, site location, communication, scheduling, industry, business, finance...
