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. ------------------------------------------------------- From: Robert van de Geijn [log in to unmask] Date: June 08, 2019 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! [1] https://www.edx.org/course/laff-on-programming-for-high-performance [2] Field G.

Anatomy of high-performance matrix multiplication. ACM TOMS, 2008. ------------------------------------------------------- From: Field G. Van Zee [log in to unmask] Date: June 06, 2019 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.

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. ------------------------------------------------------- From: Kris ONeill [log in to unmask] Date: June 05, 2019 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.
