Subject: New Book, Delaunay Mesh Generation

Delaunay Mesh Generation

Siu-Wing Cheng -- Hong Kong University of Science and Technology
Tamal Krishna Dey -- The Ohio State University
Jonathan Richard Shewchuk -- University of California at Berkeley

CRC Press, Boca Raton, Florida, Dec. 2012. xii+375 pages. $89.95.

This book is a thorough guide to Delaunay refinement algorithms that
are mathematically guaranteed to generate meshes with high quality,
including triangular meshes in the plane, tetrahedral volume meshes,
and triangular surface meshes embedded in three dimensions. It is
also the most complete guide available to Delaunay triangulations and
algorithms for constructing them. We have designed the book for two
audiences: researchers, especially graduate students, and engineers
who design and program mesh generation software. Exercises are
included; so is implementation advice.

Delaunay refinement algorithms for mesh generation construct meshes of
triangles or tetrahedra ("elements") that are suitable for
applications like interpolation, rendering, terrain databases,
geographic information systems, and most demandingly, the solution of
partial differential equations by the finite element method.

Subject: FEM in Theoretical Chem & Comp Physics, USA, May 2013

As part of FEMTEC2013, the 4th International Congress on Computational
Engineering and Sciences (, Las Vegas,
Nevada, USA, May 2013)) a mini symposium on Applications of FEM in
Theoretical Chemistry and Computational Physics will take place. The
aim of this minisymposium is to exchange and discuss ideas for the
application of the finite element method in theoretical chemistry and
computational physics. The main focus will be on methods to solve the
three dimensional Schroedinger type equations that result from Hartree
Fock / Density Functional and similar approaches applied to small and
medium sized molecules and/or periodic solids. It is hoped, that
researchers from different groups working on this and related topics
will benefit from the interaction and possible collaborative projects
emanating from this minisymposium.

Subject: Sparse Days at CERFACS, UK, Jun 2013

Sparse Days at CERFACS .... 17-18 June 2013

The annual "Sparse Days at CERFACS" will take place on the 17th and
18th of June, just before the Preconditioning 2013 meeting at Oxford.
We intend to finish formal proceedings on the Tuesday in time to allow
participants to catch the evening flight from Toulouse to London

The Sparse Days meeting will be similar in format to previous years.
No invited speakers and all talks in plenary session. As it is before
the preconditioning meeting, we might expect an emphasis on associated
areas, but contributions on any aspects of sparsity are welcome. In
particular, talks on sparse optimization and on data assimilation
would fit well with some of the current research at CERFACS.

There is no registration fee and a limited amount of very low cost
accommodation is available on site at the Meteo residences.

Registration and requests for accommodation should be sent to Brigitte
Yzel ( The deadline for doing this is 30
April 2013. However, it will help greatly with our planning if you can
let us know in advance of that deadline that you plan to come. Titles
and abstracts for presentations of 30 minutes (although you can offer
a shorter talk if you wish) should be sent to Xavier Vasseur
( The deadline is the same (30 April) but these
can be sent later than the registration.

2013. We invite you to participate in the conference by making
submissions to one or more of the technical tracks.

Some of the new features of XSEDE13 are:

A half-day devoted to the biosciences (during this half-day the
papers and abstracts, in all the tracks, will showcase the role of
cyberinfrastructure and HPC for bioscience research and development)

Publication of selected papers, from all the tracks, in the journal
of Concurrency and Computation Practice and Experience

A "Lightning Talk" plenary session where each presenter will give an
eight-minute talk followed by a special poster session

We encourage submission from any discipline (such as science,
engineering, social behavioral and economic sciences, humanities,
education, data sciences) that uses HPC and visualization to make
discoveries. Please inform students who may be interested to submit to
the technical tracks; information about travel assistance for students
is available on the website.

Subject: Mixed-Integer Non-Linear Prog, Italy, Jul 2013

We are organizing the Mixed-Integer Non-linear Programming (MINLP)
Stream at the EURO-INFORMS 2013 conference, July 1-4, 2013, Rome
(Italy). If you are interested in organizing a MINLP session or to
give a talk within a MINLP session, please feel free to contact us.
Abstracts are due by March 1, 2013.

Mixed-Integer Nonlinear Programming is a sub-field of Mathematical
Programming specializing in modelling and solving one of the most
general (and hard) classes of optimization problems: namely, problems
including both nonlinear terms and integer variables. There are
countless real-world applications: in energy production, chemical
engineering, scheduling, software verification, quantum chemistry, air
traffic management, bioinformatics, nuclear engineering, and water
distribution, for example.

Small and medium scale MINLPs are currently solved using a
Branch-and-Bound variant called "spatial Branch-and-Bound" (sBB),
where branching is allowed on continuous as well as discrete variables
that contribute to the gap between the original problem and its convex
relaxation. For large-scale variants one must currently resort to
heuristics, such as VNS, Feasibility Pump, Local Branching; or exploit
the problem structure to derive special-purpose methods. Alternative
approaches are studied for special cases of MINLP problems, like, for
example, convex MINLP and MIQP problems.

Sessions and talks focusing on both methodological developments and
applications are welcome. If you would like to submit a talk, please
use the session code 7648b5de. If you would like to contribute with
the organization of session of 4 talks, please contact one of the
stream organizers.

Subject: 40 Years of Nested Dissection, Canada, Jul 2013

Workshop Celebrating 40 Years of Nested Dissection
Location: University of Waterloo, Waterloo, Canada
Date: July 22-23, 2013

Contributed presentations are invited in all areas consistent with the
conference themes (see below).

Those interested in giving a contributed talk must submit a title and
brief abstract not to exceed 1 page by email to

Abstract submission deadline: March 31, 2013
Notification of acceptance: April 30, 2013

Nested dissection was first described by Alan George in a 1973 paper
in the SIAM Journal on Numerical Analysis. The original algorithm
aimed at reducing fill in the Cholesky factorization of a sparse
symmetric positive definite matrix associated with a discretization of
a square domain, and was shown to be optimal in terms of nonzero and
operation counts, in the asymptotic sense. Many researchers have
generalized the nested dissection algorithm to more general sparse
matrices, both symmetric and nonsymmetric. Generalized nested
dissection uses a graph that represents the sparsity structure of the
matrix; this connection has motivated an enormous body of work in the
theory and practice of graph partitioning. Nested dissection and its
generalizations have been important in sparse matrix computation, from
theory to algorithms to software, implemented on serial and parallel
computers, from desktops to today's largest HPC machines.
Furthermore, nested dissection and its generalizations have also found
their way into other scientific applications, such as analysis of
social networks and data mining.
