Subject: HiFlow3, New Release 1.3

The HiFlow3 development team is pleased to announce the availability
of HiFlow3 1.3 which can be downloaded at http://www.hiflow3.org.

Version 1.3 of the multi-purpose finite element library HiFlow3
delivers several new tools for the efficient solution of problems
modeled by partial differential equations, such as support for
periodic meshes. Furthermore, new support features that facilitate
data exchange and visualization were added. Finally, the compatibility
with different compilers was improved. The new release ships with four
new tutorials illustrating a large range of topics varying from
stabilized formulations for convection-diffusion problems to optimal
control problems.

In order to facilitate future cooperation, we have decided to release
version 1.3 under the Lesser General Public License (LGPLv3).

The HiFlow3 Version 1.3 release was carefully tested on different
architectures and using a broad range of libraries.

Best regards
The HiFlow3 Team

Subject: MOAB, A Mesh-Oriented datABase, Version 4.6 Released

Scientists use meshes to approximate a geometric domain for solving
complex engineering analysis problems. To assist in these efforts,
researchers at Argonne National Laboratory have developed the
Mesh-Oriented datABase (MOAB), a software component for representing
and evaluating mesh data. The newest release, MOAB 4.6, features
several improvements in the parallel mesh-to-mesh transfer, including
handling of spectral elements and better tolerance for point searches;
the ability to access densely-stored variable data it its native
storage; new metadata and properties handling; and one-dimensional
support in a structured mesh interface.

"Meshes act as a 'data bus' for most data in PDE-based simulation from
mesh generation, though analysis, to visualization," said Tim Tautges,
lead developer of MOAB in Argonne’s Mathematics and Computer Science
Division. “The package can represent most mesh types used in
PDE-solving applications, such as fluid dynamics, fusion modeling, and
multiphysics reactor simulation.

MOAB provides efficient storage of both structured and unstructured
mesh data, and can read and write formats used in a variety of
simulation, mesh generation, and visualization applications. Moreover,
the software can be used on a wide range of computing platforms, from
workstations to clusters and high-performance parallel systems such as
the IBM Blue Gene/P and Cray computers. Development of MOAB is
supported by DOE Offices of Science and Nuclear Energy.Further
information about downloading and documentation is available on the
website:

Subject: First Public Release, librsb Sparse BLAS Software Library

I am happy to announce the first public release of "librsb", a library
for high performance sparse matrix computations based on the
hierarchical "Recursive Sparse Blocks" (RSB) format. "librsb" is
mainly for iterative methods implementors; it features cache
efficient, multithreaded sparse matrix-vector multiplication. It is
especially effective in the symmetric and transposed variants, which
scale nearly as unsymmetric. On the Intel Sandy Bridge CPU, it was
found to perform around twice as fast as the multithreaded Intel MKL's
"mkl_dcsrmv" on many large symmetric matrices. "librsb" can be also
used via a Sparse BLAS standard interface.

Main features:
- own programming interface (<rsb.h> C/C++, ISO C binding for Fortran
- C/C++/Fortran Sparse BLAS Programming interface
- Free software licensed (LGPLv3 or later)
- Code generator for the numerical kernels
- Extensible to non-BLAS types (e.g.: int, long double)
- Test case generator and extensive test suite
- Documented with HTML, Unix man pages, examples
- Main computational kernels are parallel (using OpenMP): e.g.: sparse
matrix-vector product (e.g.: general, transposed and symmetric
variants), triangular solve and matrix assembly

- Usable from the GNU Octave custom OCT-file "sparsersb" interface
available the on Octave-forge project web site

Interested parties are welcome to test the code and submit feedback,
especially concerning the programming interface and documentation.

Subject: Teaching how to optimize dgemm

For an undergraduate class on HPC I put together a wiki that steps
students through the optimization of matrix-matrix multiplication, in
the C programming language. The student, via more than a dozen steps,
goes from a simple triple-nested loop that attains less than 5% of
peak to a highly optimized implementation that attains on my MacBook
Air around 90% of turbo performance (on a single core). The final
"microkernel", where all optimization is concentrated, is similar to
the microkernel that underlies our BLIS framework for implementing
BLAS-like functionality.

I believe the NADigest community may find use for this wiki, so here
it is: http://z.cs.utexas.edu/wiki/rvdg.wiki/HowToOptimizeGemm

I will be giving a presentation on this wiki at the SIAM SCE meeting,
in our minisymposium titled "BLAS: Evolution and Intelligent Design".

Subject: New Book, Approximation by Singular Integrals

"APPROXIMATION BY SINGULAR INTEGRALS"
BY GEORGE ANASTASSIOU AND RAZVAN MEZEI
CAMBRIDGE SCIENTIFIC PUBLISHERS, 2012

This monograph is the first one to deal exclusively with the study of
the approximation of singular integrals to the identity-unit
operator. The authors study quantitatively the basic approximation
properties of the general Picard. Gauss-Weierstrass and
Poisson-Cauchy singular integral operators over the real line. which
are not positive linear operators. In particular the authors study the
rate of convergence of these operators to the unit operator, as well
as the related simultaneous approximation and the global smoothness
preservation property of these operators. The corresponding general
approximation theory of general singular integral operators is
presented with many applications to the trigonometric singular
integral. For the convenience of the reader, the chapters of this book
are written in a self-contained style. This monograph is intended for
researchers, graduate students working in many areas of pure and
applied mathematics, including mathematical analysis, probability,
statistics, ordinary and partial differential equations.

Subject: New Book, Least Squares Data Fitting with Applications

Least Squares Data Fitting with Applications
by Per Christian Hansen, Victor Pereyra and Godela Scherer

From the back cover:

This book surveys least-squares problems from many perspectives. It is
both a comprehensive introduction to the subject and a valuable
resource to those already well versed in the area. It covers
statistical motivations along with thorough treatments of direct and
iterative methods for linear least squares and optimization methods
for nonlinear least squares. The later chapters contain compelling
case studies of both linear and nonlinear models, with discussions of
model validation as well as model construction and interpretation.

Numerical Approximation of PDEs: Adaptivity, Error Control and
Convergence
In occasion of Ricardo H. Nochetto's 60th birthday.
20-22 March 2013. Gargnano del Garda, Brescia, Italy

Adaptive finite element methods are a fundamental numerical tool in
science and engineering. They are known to outperform classical
finite element in practice and deliver optimal convergence rates when
the latter cannot. The aim of this workshop is to stimulate a fruitful
discussion regarding adaptivity, error control and convergence
analysis in the context of numerical approximation of partial
differential equations.
