We will be offering four MOOCs on edx.org, of interest to the NADigest

community, starting Jan 15, 2020:

- Advanced Linear Algebra: Foundations to Frontiers (ALAFF), offered

for the first time. 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.

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

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.

Please apply through MathJobs: http://mathjobs.org/jobs/jobs/14009

Brown University is an Equal Opportunity/Affirmative Action employer

and encourages applications from women and minorities.
