Version 2.0 of the Blaze library, one of the fastest high-performance C++ math libraries, has been released. One of the main motivations of the Blaze 1.x releases was to provide maximum performance on a single CPU core for all possible operations. However, the free lunch is over [1] and today's CPUs are not single core anymore. In order to fully utilize the performance potential of a multicore CPU, computations have to be parallelized across all available cores of a CPU. Therefore, starting with Blaze 2.0, the Blaze library provides automated shared memory parallelization. Get an impression of the possible performance boost in the Benchmarks section: http://code.google.com/p/blaze-lib/wiki/Benchmarks Blaze 2.0 is now available for download at http://code.google.com/p/blaze-lib.

SAWs is open source (BSD license), small, portable and requires only a C compiler and Unix/Linux. SAWs and its documentation can be found at http://bitbucket.com/saws/saws. An example of a running application can be accessed at http://petsc.no-ip.org:8080 Jed Brow, Matt Otten, and Barry Smith Argonne National Laboratory ------------------------------------------------------- From: Filippo Maria Denaro [log in to unmask] Date: March 19, 2014 Subject: LES database for turbulent channel flow at Re_tau=590 With this post I want to promote the availability of large eddy simulation (LES) data for the turbulent channel flow at Re_tau = 590, following the well known DNS database of Moser, Kim and Mansour. The database, which is available at: http://www.cfdlab.polimi.it/Research/LESinItaly.tar.gz has been produced within the LESinItaly initiative, an Italian collaborative framework on LES. Different research groups produced the results with different codes, in particular: - In house staggered 2nd order Finite Difference - In house cell-centered 2nd order Finite Volume - In house hybrid 4th order/pseudo-spectral solver - Open-Source FV codes Code_Saturne and OpenFOAM - Commercial FV codes Fluent and TransAT Each group has provided results with its own SGS model(s) and a no model computation on two separate grids (differing in the wall-normal resolution). You can find additional information in the README files accompanying the database. ------------------------------------------------------- From: Timo Betcke [log in to unmask] Date: March 23, 2014 Subject: Advances in Numerical Algorithms and HPC, London, Apr 2014 Date: 14-15 April Venue: University College London This workshop will bring together leading experts in Numerical Analysis and High Performance Computing to discuss novel algorithmic and software trends in these areas.

Sparse grids are a popular approach for the numerical treatment of high-dimensional problems. Where classical numerical discretization schemes fail in more than three or four dimensions, sparse grids, in their different flavors, are frequently the method of choice, be it spatially adaptive in the hierarchical basis or via the dimensionally adaptive combination technique. The aim is to bring together researchers and practitioners using sparse grids and their variants. Both theoretical and practical aspects are highly welcome. Topics of sparse grids and their applications range from uncertainty quantification to (stochastic) PDEs, from efficient data structures to parallelizations, from error bounds to high-dimensional applications, from dimensionality reduction to refinement, and much more.

Workshop on "Exceptional Orthogonal Polynomials and exact solutions in Mathematical Physics", Segovia, Spain . Exceptional orthogonal polynomials are dense families of Sturm-Liouville orthogonal polynomials with gaps in their degree sequence. They appear as eigenfunctions of rational extensions of exactly solvable potentials in quantum mechanics, and they are related to Darboux transformations and bispectrality in the theory of integrable systems. The past five years have seen a considerable activity in this field and we feel the time is ripe for bringing together many of the scientists who have contributed to this development, and others who might be interested in them. The list of invited speakers includes Alexander P. Veselov (Loughborough University, UK), Robert Milson (Dalhousie University, Canada), Antonio Durán (Universidad de Sevilla, Spain), Alexei Zhedanov* (Donetsk Institute for Physics and Technology, Ukraine), Ryu Sasaki (Kyoto University, Japan), Luc Vinet (Centre de Recherches Mathématiques, Canada), Peter Clarkson (University of Kent, UK), Manuel Mañas (Universidad Complutense, Spain), Boris Shapiro* (Stockholm University, Sweden) Lance Littlejohn (Baylor University, United States). * - to be confirmed Information: http://www.icmat.es/congresos/2014/xopconf/ There will be a limited number of grants for younger participants. Details on how to apply will be given in the website. ------------------------------------------------------- From: Jim Stewart [log in to unmask] Date: March 21, 2014 Subject: Staff Position, Uncertainty Quantification, Sandia National Labs The Optimization and Uncertainty Quantification Department at Sandia National Laboratories in Albuquerque, NM, invites applicants for an R&D staff position.
