Some examples (my apologies to those whose papers don't appear here... Perhaps we should start a list somewhere): - Exploiting functional parallelism of POWER2 to design high-performance numerical algorithms, IBM Journal of Research and Development}, 1994. (A paper that showed that high performance implementations could be generated from Fortran.) - GEMM-based Level 3 {BLAS}: High Performance Model Implementations and Performance Evaluation Benchmark, ACM TOMS, 1998. (A paper that shows how all level-3 BLAS can be implemented in terms of GEMM.) - Optimizing Matrix Multiply using PHiPAC: a Portable, High-Performance, ANSI C Coding Methodology, Proceedings of International Conference on Supercomputing, 1997. (One of the first papers that generated high performance implementations from C.) - Automatically tuned linear algebra software. Proceedings of the 1998 ACM/IEEE conference on Supercomputing, 1998. (The paper that popularized autotuning.) - A comparison of empirical and model-driven optimization. PLDI'03, 2003. (The paper that showed that the parameters for ATLAS can be analytically determined, thus not requiring autotuning.) - Anatomy of high-performance matrix multiplication. ACM TOMS, 2008. (The paper that described the GotoBLAS approach to GEMM implementation and is often used in courses.) - Benchmarking GPUs to tune dense linear algebra. Proceedings of the 2008 ACM/IEEE conference on Supercomputing, 2008. (An influential paper on how to optimize for GPUs.) We recently wrote a paper on how to parallelize the GotoBLAS approach to implementing GEMM for many-core architectures (the Intel Xeon Phi processor and the IBM PowerPC A2 used by IBM's BG/Q supercomputer), achieving exceptional performance. This paper has been accepted by IPDPC, and the reviewers noted that it has potentially pedagogical value. For this reason, given that instructors are preparing courses for spring at this moment, we thought we'd share the technical report version of this paper: T. M. Smith, R. van de Geijn, M. Smelyanskiy, J. R. Hammond, and F. G. Van Zee. Opportunities for Parallelism in Matrix Multiplication. FLAME Working Note #71, 2013. http://www.cs.utexas.edu/users/flame/web/FLAMEPublications.html. ------------------------------------------------------- From: Robert van de Geijn [log in to unmask] Date: January 14, 2014 Subject: Massive Online Open Course (MOOC) on Linear Algebra For the last many months, my wife (Dr. Maggie Myers) and I have been working with a team of students on a Massive Open Online Course (MOOC) titled "Linear Algebra - Foundations to Frontiers". This course was originally scheduled to launch on January 15, 2014, but has now been delayed to January 29, 2014. The official nnouncement for this course is posted at https://www.edx.org/school/UTAustinX/allcourses. This is a second posting to NA Digest regarding this course. This particular course may be of interest to the NA Digest community because it links the fundamental concepts in linear algebra (LA) that are taught in an introductory-level college course to the latest programming techniques that we have developed over the last 15 years as part of the FLAME project. The idea is as follows: the abstractions that are important when introducing the mathematics of LA are reflected in the layering of LA libraries, such as the BLAS and LAPACK. Therefore, computationally inclined students will likely benefit from a simultaneous introduction to the mathematics and programming methods. The course covers the same topics as would be covered in a typical linear algebra course, including proof techniques. We use iPython Notebooks to help the students link that knowledge to a simple LA library they build that mirrors the BLAS and parts of LAPACK. We use an API that hides indices (similar to our FLAME APIs for C and M-script but for Python) so that students can focus on learning the concepts rather than getting bogged down in programming details. Similar APIs are also used in the development of BLIS, libflame, and Elemental, which are all part of a new dense linear algebra software stack. ------------------------------------------------------- From: Bruce Bailey [log in to unmask] Date: January 08, 2014 Subject: New Book, Semi-Lagrangian Approximation Schemes Announcing the January 1, 2014, publication by SIAM of: Semi-Lagrangian Approximation Schemes for Linear and Hamilton–Jacobi Equations, by Maurizio Falcone and Roberto Ferretti 2014 / xii + 319 pages / Softcover / 978-1-611973-04-4 / List Price $99.00 / SIAM Member Price $69.30 / Order Code OT133 Also available in e-book format on Google Play This largely self-contained book provides a unified framework of semi-Lagrangian strategy for the approximation of hyperbolic PDEs, with a special focus on Hamilton–Jacobi equations. The authors provide a rigorous discussion of the theory of viscosity solutions and the concepts underlying the construction and analysis of difference schemes; they then proceed to high-order semi-Lagrangian schemes and their applications to problems in fluid dynamics, front propagation, optimal control, and image processing. The developments covered in the text and the references come from a wide range of literature.

A desired, but flexible, start date of June 1, 2014 is expected. The main effort of the position will be dedicated to developing numerical models and multilevel solvers for simulating complex multiscale physical systems, particularly those of MHD. Such models are described by coupled systems of time-dependent nonlinear PDEs and present many interesting challenges common to models used in physics, mathematics and, more generally, in the numerical simulation and analysis of physical phenomena. The goals of this project are to develop numerical models that preserve the important physical quantities of the MHD system and to employ advanced mathematical algorithms that will allow analysis of MHD applications in real time. Additional research opportunities are available in the analysis of discretization and multigrid techniques for problems in particle transport and nonlinear energy laws. It is expected that the postdoctoral researcher will work closely with the Adler/MacLachlan research group, including graduate students involved in the project. Initial funding is for one year and may include opportunities for teaching. A PhD and relevant expertise in applied mathematics or scientific computing is expected, with a preference for experience in computational PDEs and/or numerical linear algebra. Previous interdisciplinary project experience is a plus.

Advection-reaction-diffusion (ARD) problems describe in an efficient way several real phenomena, so as to capture an outstanding interest in the scientific research. In particular, reaction-diffusion models have been widely studied while open questions still hold for problems with advection terms too. In this project we tackle the application to the biochemistry of lakes, sea and oceans. These dynamics are well described by ARD models and their accurate description is essential to study accurately the carbon cycle and the earth climate. The aim of this project is to address both theoretical aspects (conservative formulation of the boundary conditions for lagrangian numerical solvers) and application aspects (development of a lagrangian algorithm to numerically solve ARD problems to be used as a reference solver).
