The current version of the survey can be found at: http://www.netlib.org/utk/people/JackDongarra/la-sw.html The aim is to put in “one place” the source code that is freely available for solving problems in numerical linear algebra, specifically dense, sparse direct and iterative systems and sparse iterative eigenvalue problems. Please send Ahmad Abdelfattah [log in to unmask] updates and corrections. We will post a note on the na-digest when the new list is available. Thanks, Jack and Ahmad ------------------------------------------------------- From: Michele Martone [log in to unmask] Date: May 02, 2015 Subject: Release 1.2 of librsb, Sparse BLAS Software Library Version 1.2 of the "librsb" library for high performance sparse matrix computations based on the "Recursive Sparse Blocks" (RSB) format is out and available for download. librsb is mainly for iterative methods implementors; it features cache efficient, multithreaded sparse matrix-vector multiplication, and it is especially fast in the symmetric and transposed variants. Many options and further matrix operations are available. Both Sparse BLAS and the own interfaces are supported (C, Fortran). Transparently usable in GNU Octave via the sparsersb package/command. Main improvements of librsb-1.2 are: - faster runtime autotuning of structure and threads for sparse matrix-vector/matrix-matrix multiply and triangular solve: now uses a parallel merge/subdivision based algorithm - speeded up triangular solution of a matrix by multi-vector - introduced extension BLAS property blas_rsb_autotune_next_operation to trigger auto tuning at the next USMV/USMM call - collection/report of time spent in librsb routines now possible (a simple built-in profiler) - further Encapsulated PostScript (EPS) matrix rendering options - improved benchmark program for large parameter studies (converts and reuses matrices rather than re-reading them from disk) - binary performance records write/read/combine support, also with Intel MKL CSR built-in comparison; LaTeX tables output and stats Source code (LGPLv3 licensed), documentation, change log and extensive benchmark results available on: http://sourceforge.net/projects/librsb ------------------------------------------------------- From: Jan Hidders [log in to unmask] Date: April 29, 2015 Subject: EDBT Summer School, Graph Data Management, Spain, Aug 2015 Call for Applications 12th EDBT Summer School on Graph Data Management 31 August - 4 September 2015 Palamós, Spain http://edbt2015school.win.tue.nl/ The theme for the 12th EDBT Summer School is "Graph Data Management".

Science and technology play an increasingly important role in equipping and supporting the armed forces. Mathematics is fundamental to these disciplines, providing a framework for understanding and solving the varied and complex problems faced, and is used to model military systems and scenarios. These models can be used to estimate system performance, suggest improvements, or find weaknesses of real systems. Conference Topics The conference will cover the following themes: Data analysis: data and text mining, data fusion, information visualization, multidimensional data analysis; Modelling and Estimation: electromagnetic models, estimation theory, Markov models, non-linear models, mathematical models, simulation; Operational Analysis: cost benefit analysis, counter-terrorism, risk management, intelligence analysis, behaviour analysis; Security: cryptography and coding, security systems, secure communications; Signal Processing: adaptive processing, computer vision, digital signal processing, distributed sensor processing, emitter location, image processing, signal enhancement, super-resolution, synthetic aperture radar, time series analysis; Statistical Methods: Bayesian techniques, classification, detection, identification, tracking, Monte Carlo methods, particle filters, pattern recognition. Papers or posters will be accepted on the basis of a 300-500 word abstract which should be submitted by 14 May 2015 by e-mail to [log in to unmask] Further Information http://www.ima.org.uk/conferences/conferences_calendar/4th_mathematics_in_defence.c fm.html ------------------------------------------------------- From: Andrea Bonito [log in to unmask] Date: May 03, 2015 Subject: Graduate Winter School, Geometric PDEs, USA, Jan 2016 The Department of Mathematics at Texas A&M University is offering a winter school for graduate students on "Geometric PDEs and Their Approximations". January 10 - 16, 2016. Lecturers: Ricardo H. Nochetto (UMD) and Andrea Bonito (TAMU); January 11 - 16 Deal.II tutorial: Timo Heister (Clemson); January 10 Short Description: A comprehensive approach to the formulation and discretization of geometric partial differential equation governing processes will be provided. The topics discussed will center around differential geometry, calculus of variations, gradient flows and discretization using finite element methods. Emphasis will be made to applications and in particular in biophysics and material science. Afternoon laboratory sessions will serve as numerical illustration to the topics discussed in the lectures and will provide insights on the behavior of the algorithms. During these sessions students will have the choice of using either MATLAB or deal.ii/C++. Thanks to the support of the US National Science Foundation and the Institute for Applied Mathematics and Computational Science, funding is available to support the travel and local expenses for several participants. We would appreciate if you could forward this announcement to possibly interested graduate students.
