Subject: Massive Open Online Courses for Spring 2020

We will be offering four MOOCs on, 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

Please help raise awareness of these opportunities.

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,

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 for detailed information

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" ( 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:

Brown University is an Equal Opportunity/Affirmative Action employer
and encourages applications from women and minorities.
