Subject: Change of address for Tim Davis
After many fruitful years at the University of Florida, I am very
happy to announce that I have taken a position in the Computer Science
and Engineering Department at Texas A&M University. My new address
is:
Tim Davis
Dept of Computer Science and Engineering

College Station TX 77843-3112
http://engineering.tamu.edu/cse/people/davis-tim
email: davis@cse.tamu.edu
office: (979) 845-4094
My software repository is still hosted at the University of Florida,
as is the University of Florida Sparse Matrix Collection, at
http://www.cise.ufl.edu/research/sparse. I will post an update when I
move the collection and my software to Texas A&M.
I'm also looking for a postdoc or two, funded by Texas A&M. The
position was posted earlier in the NA Digest:
http://www.netlib.org/na-digest-html/14/v14n15.html#5 I've received
several excellent applications but I'm still considering additional
candidates. I'm looking for PhD students as well. The postdocs and
PhD students will be working with me in my lab here at Texas A&M,
recently designated by NVIDIA as a CUDA Research Center, in support of
my work in GPU / many-core algorithms.

Subject: Notes for MOOC on Introductory Linear Algebra
During Spring 2014, we offered a Massive Open Online Course (MOOC)
titled "Linear Algebra: Foundations to Frontiers (LAFF)". With this
course, we attempt to appeal to computation oriented audiences by
linking abstractions in the mathematics (e.g., viewing matrices by
rows or columns) with abstractions in algorithms and implementations
(partitioning of arrays into rows, columns, and blocks). For the
NADigest audience, this can be described as "from the start, the
layering in the mathematics is linked to the layering in the BLAS and
LAPACK".
We now make the materials that were created for this course available.
At the core is a 900 page document that includes homework with
detailed solutions, links to more than 250 short videos, and
programming activities in Python, using IPython Notebooks.
Given feedback from participants in the MOOC, we have concluded that
these materials are valuable to a broad audience that includes
beginning students who have not had a previous exposure to linear
algebra but also professionals with advanced degrees who want to
review the foundations of linear algebra. Beginning graduate students
can use the notes to learn how to think in terms of partitioned
matrices and how performance relates to architecture (an enhancement
activity in the course) in preparation for a graduate level course in
numerical linear algebra. Educators may wish to use the notes in a
"flipped classroom" setting.

Subject: Blaze 2.1 Released
After three month, just in time for ISC'14, version 2.1 of the Blaze
C++ math library has finally been released! The focus of this newest
release is the improvement and extension of the shared memory
parallelization capabilities. And this gives you some new exiting
features: In addition to the OpenMP parallelization, Blaze 2.1 now
also enables shared memory parallelization based on C++11 and Boost
threads. With that, shared memory parallel execution is now available
for virtually every platform and compiler. Additionally, the
underlying architecture for the parallel execution and automatic,
context-depending optimization has been significantly improved. This
not only improves the performance and determinism of the
parallelizations, but also for instance enables an efficient parallel
handling of computations involving block structured vectors and
matrices. Therefore Blaze 2.1 should prove to be the fastest and most
flexible Blaze release yet.

Subject: CHEBFUN Version 5 Release
We are pleased to announce the release of Chebfun Version 5, available
for download at http://www.chebfun.org/download/
Version 5 has involved a complete rewrite of the code with a focus on
clarity to make it more accessible and extensible. The code is hosted
on GitHub (https://github.com/chebfun/), and we welcome new developers
to get involved.
Chebfun is an open-source software system for numerical computing with
functions. The mathematical basis is piecewise polynomial
interpolation implemented with what we call “Chebyshev technologyâ€.
The foundations are described, with Chebfun examples, in the book
Approximation Theory and Approximation Practice (L. N. Trefethen, SIAM
2013). Chebfun has extensive capabilities for dealing with linear and
nonlinear differential and integral operators, and also includes
continuous analogues of linear algebra notions like QR and singular
value decomposition. The Chebfun2 extension works with functions of
two variables defined on a rectangle in the x-y plane.
To get a sense of the breadth and power of Chebfun, a good place to
start is by looking at our Examples at http://www.chebfun.org/examples/
or the introductory Guide at http://www.chebfun.org/docs/guide/
New features in V5 include:
- First official release of Chebfun2 for bivariate computing
- Powerful new bivariate rootfinding algorithms
- Major speedups of conv, polyfit, abs, inv, and pde15s
- O(nlogn) codes leg2cheb, cheb2leg for coefficient conversion
- Option for algorithms based on first kind Chebyshev points
- A Chebfun constructor option 'equi' for equispaced data
- A 'periodic' flag for Fourier interpolants instead of Chebyshev
- Ultraspherical spectral methods for ODEs
- Improved graphical interface (chebgui) for ODE capabilities

Subject: Young Researchers in Pure & Applied Math, Brazil, Dec 2014
In Brazil, due to its continental dimensions with several universities
distant from major research centers, many new Ph.D. graduates join
these universities and end up distancing themselves from their
original research groups. This often hinders the development of their
research and, consequently, their ongoing professional career. For
this reason, young researchers decided to create an appropriate
framework to share research results, thus giving rise to 'I Brazilian
Congress of Young Researchers in Pure and Applied Mathematics'.
Thematic Sessions: Algebra, Functional Analysis, Numerical Analysis,
'Set Theory, Topology and Banach Spaces', Biomathematics, Partial
Differential Equations, Mathematical Physics, Geometry, Discrete
Mathematics, Probability and Statistics, Optimization, Operations
Research, Orthogonal Polynomials, Singularities and Foliations,
Dinamical Systems

Subject: PhD Position, Sci Comp, Power Generation, Uni Leicester
Applications are invited for a 3.5-year tax-free EPSRC CASE
studentship of ~£15850 p.a. in the College of Science and
Engineering. The studentship is available to UK Home students, with
some exceptions. Please check your eligibility at
http://www.epsrc.ac.uk/skills/studentships/help/eligibility/
before applying.
The project aims to advance on the current scientific computing
methods for power plant turbomachine design. It includes an
industrial placement in Rugby at ALSTOM UK LTD, a world-leader in
power plant construction. The successful applicant will join a team
of applied mathematicians and engineers.
Mathematically, such an advancement hinges on the novel use of a
posteriori error bounds for hyperbolic and/or convection-dominated
systems of partial differential equations. This project will extend
these cutting edge mathematical ideas to compressible and
incompressible flows and implement them in industrial software.
The project will begin on the 1st of October 2014 or as soon as
possible thereafter.
To apply for the post, please email a CV, evidence of academic
attainment, and contact details for 2 academic referees to Dr. E.H.
Georgoulis at eg64@le.ac.uk. Informal enquiries are welcome.
