This is a full-semester graduate course on numerical linear algebra. These materials can be used for self-study, as a supplement to tradition textbooks, and/or as an alternative to such textbooks. Materials will be released incrementally as the semester progresses. - Linear Algebra: Foundations to Frontiers (LAFF), offered for the tenth time. This is a full-semester introduction to linear algebra designed with those interested in computing in mind. - LAFF-On Programming for Correctness, offered for the third time. It is a 6 week course that teaches some of the core mathematics that underlies reasoning about programming, with an application to matrix computations. The techniques have been key to the development of the libflame library, an alternative to LAPACK. - LAFF-On Programming for High Performance, offered for the second time. This is a 4 week course that uses matrix-matrix multiplication to teach core ideas of high performance. Learners discover some of the basic techniques that underlie the BLAS-like Library Instantiation Software (BLIS) framework. A related paper will receive the SIAM Activity Group on Supercomputing Best Paper Prize in February 2020. These courses can be audited for free or taken for a Verified Certificate ($49). Related materials are also made available for free, independent of these courses. For additional information, visit ulaff.net. Please help raise awareness of these opportunities. ------------------------------------------------------- From: Elise DE DONCKER [log in to unmask] Date: December 26, 2019 Subject: CFP, Large Scale Computational Science, Italy, Jul 2020 This is an invitation for contributions for the Workshop on Large Scale Computational Science (LSCS), to be held with ICCSA 2020, July 1-4, 2020 in Cagliari, Italy, http://www.iccsa.org The LSCS workshop focuses on numerical and symbolic methods and simulations, algorithms and tools for developing and running large scale computations. Apart from traditional algorithms, problem solving tools include techniques such as neural networks and machine learning. Parallelism, scalability and numerical precision are important in view of the large computational requirements and data, as well as system architectures supporting the applications: massively parallel systems, GPUs, many-integrated-cores, hybrid systems and distributed (cluster, grid/cloud) environments. Applications will be considered from areas including computational mathematics and statistics, computational physics, fluid dynamics, quantum physics, molecular dynamics, materials science/nanotechnology, computational biology/medicine, bio- and neuroinformatics, environmental and climate modeling. Themes: Large scale computations, massive parallelism, modeling, simulations, data and applications Paper submission: Deadline (tentatively): March 15, 2020 Format: 10-16 pages in LNCS format, see the ICCSA Conference URL at http://www.iccsa.org/Instructions-for-authors for detailed information ------------------------------------------------------- From: Scott Field [log in to unmask] Date: December 29, 2019 Subject: Six Postdoc Positions, Brown Univ, ICERM We invite applications for postdoctoral positions as part of a semester-long Fall 2020 program on "Advances in Computational Relativity" (https://icerm.brown.edu/programs/sp-f20/) at ICERM, Brown University in Providence. For full consideration, applicants must submit an AMS Standard Cover Sheet, cover letter, curriculum vitae (including publication list), research statement, and three letters of recommendation. While priority will be given to applications received before January 4, 2020, we will continue to accept applications until all six appointments are filled.
