Subject: History of least-squares boundary matching for PDEs


Can NA Digest readers help me with a bit of history? In a Stanford
technical report of 1969 (http://i.stanford.edu/TR/CS-TR-69-121.html),
Cleve Moler recommended least-squares fitting on the boundary as a
method for solving Laplace problems. It seems unlikely this could
have been the first use of least-squares boundary matching for PDEs,
but can somebody point me to anything earlier?

This question is part of a larger story, I believe, of a transition
from square to rectangular thinking in a number of computational
areas. When Householder proposed reflectors for QR factorization in
1958, for example, his matrices were square; only later did many of us
come to regard the "skinny" variant as more fundamental. For years
people investigating problems of infinite matrices mainly used a
square rather than rectangular "finite section method." Approximation
theorists put great effort into methods based on interpolation rather
than least-squares (Fekete points, Lebesgue constants,...). In
Fourier analysis we had centuries of attention to bases before people
started talking about redundant bases and frames. And so on into this
era of data science, where rectangular seems often more natural than
square.

Subject: MOOC, Programming for High Performance, now in session


A few weeks ago we announced that "LAFF-On Programming for High
Performance" [1] was open for registration. This free-to-audit,
four-week course developed by UT-Austin faculty Robert van de Geijn,
Maggie Myers, and Devangi Parikh is now in session.

This course exposes techniques for attaining high performance through
carefully scaffolded exercises that illustrate how the BLAS-like
Library Instantiation Software (BLIS) [2] and other such libraries
implement matrix-matrix multiplication based on Goto's algorithm [3].
Topics span instruction-level parallelism via vector intrinsic
functions, reusing data in caches, and multithreaded parallelization
via OpenMP.

We believe this course is appropriate for a novice yet of interest to
an expert.

Please help us spread the word!

Subject: BLIS 0.6.0 now available


The Science of High-Performance Computing (SHPC) research group at The
University of Texas at Austin is pleased to announce BLIS 0.6.0, made
possible thanks to our partnership with AMD.

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 end-users to build
libraries that implement a superset of the BLAS, which can be called
via conventional BLAS-like or object APIs, or via standard BLAS
interfaces. (An optional CBLAS API is also available.)

BLIS 0.6.0 provides accelerated dgemm on small/skinny matrix problems
for a wide range of modern microarchitectures, including Intel Haswell
through Coffee Lake and AMD Zen-based Ryzen/Epyc. AMD's upcoming Zen2-
based Ryzen/Epyc will also be supported. For now, this class of small
matrix problems is only optimized for double-precision real gemm.
Similarly, the new implementation does not yet support multithreaded
parallelism. Still, measured speedup for problems with at least one
dimension exceedingly small (e.g. m = 6) is dramatic. Performance
results are illustrated on two systems--an Intel Kaby Lake and an AMD
Epyc--in a new markdown document available via the web [1] as well as
the BLIS source distribution.

and related information, please visit the BLIS github website [2].

Subject: Python codes for NA/scicomp textbook


I have translated into Python all 45 functions and 160+ examples from
the textbook Fundamentals of Numerical Computation (SIAM), co-authored
by Rich Braun and myself.

Book website: http://tobydriscoll.net/fnc/
New codes: https://github.com/tobydriscoll/fnc-extras/tree/master/python

The text and codes cover at an advanced undergraduate level the basics
of dense matrix factorizations, rootfinding and nonlinear
least-squares, interpolation, initial-value problems, EVD and SVD,
Krylov iterations, boundary-value problems, and the method of lines
for PDEs.

The codes require nothing beyond Python 3, scipy, and numpy, and
matplotlib. They complement the previously supplied Julia and original
MATLAB versions of the codes.

Subject: New Book, A Mathematical Introduction to Electronic Structure Theory


A Mathematical Introduction to Electronic Structure Theory
By Lin Lin and Jianfeng Lu

Based on first principle quantum mechanics, electronic structure
theory is widely used in physics, chemistry, materials science, and
related fields and has recently received increasing research attention
in applied and computational mathematics. This book provides a
self-contained, mathematically oriented introduction to the subject
and its associated algorithms and analysis. It will help applied
mathematics students and researchers with minimal background in
physics understand the basics of electronic structure theory and
prepare them to conduct research in this area. The book is written for
advanced undergraduate and beginning graduate students, specifically
those with mathematical backgrounds but without a priori knowledge of
quantum mechanics, and can be used for self-study by researchers,
instructors, and other scientists

This book encompasses the required classical Fourier theory in the
first part in order to give deep insight into the construction and
analysis of corresponding fast Fourier algorithms in the second part,
including recent developments on non-equispaced and sparse FFTs in
higher dimensions, and spherical Fourier transforms. In the third
part of the book contains a selection of applications, in particular
research results on non-linear function approximation by exponential
