Subject: New software release, p4est 1.1

We are pleased to announce the release v1.1 of the p4est software.
p4est is a C library to manage a collection (a forest) of multiple
connected adaptive quadtrees or octrees in parallel. p4est offers
fast absolute-time and low-memory algorithms for a feature-complete
set of octree-based AMR operations. p4est has been shown to scale to
the full size of the Jaguar (2011) and Juqueen (2014) supercomputers
and is used in several production science applications. This version
is considered stable and includes all recent updates.

The software is freely available at where we also link
to a howto document, technical papers, and inline source

There is an archived mailing list for discussion of any p4est related
issues; please see Everybody is
free to subscribe. We are happy to help and respond to any issues
that may arise.

Enjoy! The p4est developers,

Subject: Call for Proposals, Gene Golub SIAM Summer School 2016

SIAM is calling for Letters of Intent proposing topics and organizers
for the 2016 Gene Golub SIAM Summer School (G2S3). Preference will be
given to a computational linear algebra theme, but Letters of Intent
in all areas of applied and computational mathematics will be

It is expected that the program will run two weeks for 40 to 50
graduate students in 2016. SIAM will contribute up to $95,000 towards
the running of the summer school.

Information about the G2S3 program, including the composition of the
G2S3 committee, can be found at

Information about the 2015 G2S3 can be found at and the archives of earlier G2S3s can be
found at The deadline
for Letters of Intent is January 31, 2015. For more information see

Subject: Winter School on CFD, Switzerland, Nov 2014

The Institute of Computational Science (ICS) at the University of
Lugano (USI) is pleased to announce a winter school on ''Computational
Fluid Dynamics - Modeling, Simulation, Validation''
November 10 to November 14, 2014
Lugano, Switzerland

The winter school will cover the modeling of fluid flow, turbulence
and all major numerical discretization schemes, such as finite
differences, spectral methods, finite elements, and finite volumes.
Moreover, two surface flow and complex applications such as combustion
modeling and their validation will be treated.

For more information, please see below or visit

Speakers: Dominik Obrist (Uni Bern); Sven Groß (RWTH Aachen); Ioannis
Mantzaras (PSI Villingen); Patrick Jenny (ETH Zürich)

The course will start with an introduction to the Navier-Stokes
equations, i.e. the mathematical model for incompressible flow, and
with the numerical solution of the incompressible Navier-Stokes
equation, including the direct numerical simulation of turbulent flow
using finite and compact differences and spectral methods.

Finite elements for fluid flow and free surface flow will be treated
next, followed by combustion modeling. Basic thermodynamic principles
as well as the validation of the numerically obtained results will be
discussed. In the last part of the course, finite volumes methods for
compressible flow will be considered.

The course is designed to give a comprehensive overview on
state-of-the art numerical techniques not only for laminar and
turbulent flow, but also for two surface flow and combustion. In
addition to numerical methods, also their application and validation
will be considered.

Differentiation (AD) and adjoint methods. We also encourage
presentations in related, symbiotic areas including: source code
augmentation; ODE/PDE control/sensitivity; data assimilation; design
optimisation; interval analysis; computational finance; etc. This
workshop is informal, with no published proceedings, allowing for the
