Subject: BLIS 0.3.2 now available

We are pleased to announce BLIS 0.3.2, made possible in part thanks to
a flurry of community activity and contributions as well as funding
from NSF and industry.

BLIS is a software framework for rapidly instantiating high-
performance BLAS-like dense linear algebra operations. Aside from
being a developer's tool, the framework also allows all users to build
libraries that implement a superset of the BLAS while providing a BLAS
compatibility interface by default. (An optional CBLAS API is also
available.)

BLIS 0.3.2 provides varying levels of optimized kernel support across
a variety of microarchitectures, from the well-supported Intel
Haswell, Broadwell, Skylake, and Kabylake CPUs to others, such as
ARMv7/ARMv8, for which we offer more preliminary support. We also
provide optimizations for AMD's recent Zen microarchitecture as well
as initial real-domain support for the AVX-512 instruction set
(Intel's Skylake-X and Knights Landing).

Other recent developments include fully integrated BLAS test drivers,
a rewritten configure-time hardware detection heuristic, the ability
to build multi-architecture libraries where kernels are selected at
runtime, and implementations of recently-published research on
inducing complex matrix multiplication.

Subject: MOOC on Programming for Correctness

"Program testing can be used to show the presence of bugs, but never
to show their absence!"  -- Edsger Dijkstra

On May 15, 2018, "LAFF-On Programming for Correctness" starts
again on the edX platform:
https://www.edx.org/course/laff-on-programming-for-correctness .
A short video that launches Week 0 can also be viewed on YouTube:
https://youtu.be/P2Yx8TPKiDY .

This MOOC is a humble attempt to share some of the foundational
mathematics that enables one to derive programs to be correct,
hand-in-hand with their proofs of correctness.  We think it can
benefit novices as well as established software scientists.

The course builds upon the "FLAME" project that yielded PLAPACK, the
libflame library, and the BLAS-like Library Instantiation Software
(BLIS).  The techniques also influenced the Elemental library for
distributed memory architectures.  It exposes some of the "secret
sauce" that has allowed us to rapidly develop portable
high-performance libraries with a high degree of confidence.

We gratefully acknowledge support for this MOOC from MathWorks, the
National Science Foundation, and The University of Texas at Austin.

George A. Anastassiou
Nonlinearity: Ordinary and Fractional Approximations by Sublinear and
Max-Product Operators

Approximation by sublinear operators with applications to Max-product
operators is a new trend in approximation theory. These operators are
nonlinear and rational giving very fast and flexible
approximations. In this book we focus more in approximations under the
presence of ordinary and fractional smoothness. We present both the
univariate and multivariate cases. We deal also with approximations
under convexity. The book's results are expected to find applications
in many areas of pure and applied mathematics, especially in
approximation theory and numerical analysis in both ordinary and
fractional sense.

Subject: Gene Golub Memorial Workshop, China, Apr 2018

Zhong-Zhi Bai (Chinese Academy of Sciences, China) and Dan-Fu Han
(Hangzhou Normal University, China) organized an International
Workshop on Matrix Computations to honor the memory of Gene Golub in
Hangzhou, China, on April 20–24, 2018. Former students, collaborators
and friends of Gene from China, Hong Kong, Russia and Switzerland
presented research works on the favorite topics of Gene: linear
equations, inner-outer iterations, secular equations, matrix splitting
and preconditioning, block triangular and skew-Hermitian splitting
methods, SOR-like methods, HSS preconditioner for saddle point
problems, and so on. For each year from 2010 to 2017, Frank Luk and
Walter Gander organized a Golub Memorial Day at the Hong Kong Baptist
University. We are pleased that Zhong-Zhi Bai has agreed to continue
this tradition in China. As we all know, Gene loved to encourage and
promote young talents, including many from China (he also loved
Chinese food!). The students at the Hangzhou workshop were moved and
inspired by the many stories they heard about Gene. They got to
understand why there is an annual SIAM summer school organized in
Gene's name. So the legacy of Gene Golub (1932-2017) is present and
alive! The next Golub Memorial Workshop will be held in Lanzhou,
China, in April 2019.

Subject: Hyperbolic Conservation Laws, Belgium, Jun 2018

Hereby, I would like to kindly invite you to participate in the summer
school on hyperbolic conservation laws at the university of Hasselt,
Belgium, from June 25-27, 2018.

Many processes are described by physical laws expressing the
conservation of mass, momentum, or energy. Commonly, the related
mathematical models are systems of partial and ordinary differential
equations. One illustrative example is the air flow around planes
under standard flight conditions. In mathematical terms, this flow is
modelled by the Navier-Stokes or the Euler equations, which form a
particular set of mathematical conservation laws.

The focus of the summer school is on hyperbolic conservation laws.
The mathematical treatment of conservation laws is a complex and
challenging task. In comparison to other types of equations, the
hyperbolic conservation laws may have multiple solutions, which may
become non-smooth. This makes both the mathematical analysis and the
numerical approximation quite cumbersome. Most of the available
results are restricted to simplified and hence non-realistic cases,
like one-dimensional problems. In the general situations the existence
of solutions is still an open research question. Also, in case of
multiple solutions, entropy criteria have to be defined to select the
physically relevant solution.

The goal of this summer school is to give the participants a basic
introduction to the analysis and the numerics of hyperbolic
conservation laws. The focus will be more on an introduction to the
concepts including their applications rather than a complete and
rigorous discussion of the theory. The summer school will therefore be
amenable to mathematicians, engineers and scientists and will be
presented in a genuine interdisciplinary context. The summer school
will be open to participants having a basic knowledge in calculus and
linear algebra courses as they are taught to engineers and
scientists. All sessions will be hands-on, meaning that sufficient
time for exercises and their discussion is planned.
