Subject: Chombo 3.1 is available

The Chombo team is happy to announce the release of Chombo 3.1.

The Chombo software package provides a set of tools for implementing
finite difference methods for the solution of partial differential
equations on block-structured adaptively refined rectangular grids
with embedded boundaries. Both elliptic and time-dependent modules are
included. Support for parallel platforms and standardized
self-describing file formats are included.

Chombo's design is flexible and accessible. Users will be able to
develop parallel applications to solve the partial differential
equations of interest with far shorter development times than would be
possible without the infrastructure. Very careful design and
documentation allows users to access the software at many levels.
They will be able to use Chombo to simply adapt the example
applications to solve scientific problems or to investigate deep
technical issues of adaptive mesh refinement algorithms.

Chombo is built using a combination of C++ and Fortran and uses MPI
message-passing for parallel execution. The code is straightforward
to build using GNU Make and the documentation provided. Chombo has
been ported to a variety supercomputers and runs on laptops and

See for more details about Chombo and to find out more about the release and to
download the software.

Subject: Scalable direct eigenvalue solver ELPA for symmetric matrices

Scalable direct eigenvalue solver ELPA for symmetric matrices: hybrid
version released

"ELPA" is a new direct eigensolver library that addresses scalability
and performance, especially for parallel applications. ELPA builds on
the ScaLAPACK type interfaces that are often used in existing
implementations, but key parts of the eigenvalue solution are then
replaced with ELPA's own routines in an easy-to-use way. The library
is particularly useful when a substantial part of all eigenvalue /
eigenvector pairs is needed. Released under an LGPL-like license, ELPA
has been successfully tested for matrix sizes up to 680,000 and with
up to 294,000 CPU cores on a BlueGene/P system.

Excellent scalability within ELPA is already achieved in an MPI-only
implementation. In addition, a hybrid OpenMP/MPI version of ELPA has
just been released, extending the range of supportable applications to
those that already utilize a mixed communication pattern.

For details on the ELPA consortium, the solver and access to the
source code, see

Subject: GreenNets 2012, Spain, Oct 2012

2nd International Conference on Green Communications and Networking -
GreeNets 2012, 24th and 26th October 2012, Gandia, Spain

Global warming and climate change have been a growing worldwide
concern. Six sources, i.e., transportation, power, buildings,
industry, agriculture and forestry, and land use, have been identified
as major contributors to the rise of global carbon dioxide (CO2). The
mobile industry is seen as a potential enabler to reduce greenhouse
gases contributed by these six sources provided that appropriate
measures are implemented. On the other hand, the mobile industry
itself will also contribute to CO2 emission through network
operations, mobile equipments, etc. To meet the requirement of
low-carbon economy development, it is necessary to reduce the
operation expenditure or energy consumption of mobile networks, while
maintaining acceptable quality of service. This conference will
explore and explain the scope and challenges of designing, building,
and deploying GreeNets. In this regard, the conference aims to
establish a forum to bring together research professionals from
diverse fields including green mobile networks, system architectures,
networking & communication protocols, applications, test-bed and
prototype, traffic balance and energy-efficient cooperation
transmission, system and application issues related to GreeNets.

Subject: Postdoc Position, Optimization, Technical Univ of Denmark

A Post Doc position in Practical Optimal First-Order Methods is
available at DTU Informatics, Technical University of Denmark,
starting August 1, 2012. It is funded by the ERC project
“High-Definition Tomography” headed by Professor Per Christian Hansen.

The goal of the ERC project is to develop computational algorithms for
tomography that can incorporate many different kinds of available
prior information in order to produce high-definition reconstructions,
i.e., sharper images with more reliable details.

The Post Doc will develop practical first-order optimization methods
for smooth problems, and extensions of these methods to non-smooth
problems. The project involves development of prototype
implementations of the algorithms and validation on selected problems
in, e.g., computational geoscience.

The Post Doc is also expected to contribute to the section’s teaching
in the areas of scientific computing and large-scale methods for
optimization (max 20% of the total time can be associated with

Two PhD positions are available at DTU Informatics, Technical
University of Denmark, starting August 1, 2012. Both are funded by the
ERC project “High- Definition Tomography” headed by Professor Per
Christian Hansen.

The goal of this project is to develop the enabling mathematical
technology and computational algorithms to produce a new generation of
tomographic reconstruction methods that can incorporate many different
kinds of available prior information in order to produce
high-definition reconstructions, i.e., sharper images with more
reliable details.

Project 1: Statistical Priors in Variational Reconstruction Methods

This PhD project aims at bridging the gap between Bayesian and
variational reconstruction methods by setting up a mathematical and
computational framework that utilizes the connections between
parametric priors for the solutions, in the form of probability
distributions, and corresponding norms or filters.

Project 2: Training Sets in Large-Scale Reconstruction Methods

This PhD project aims at providing a theoretical and methodological
framework for the use of training sets as non-parametric priors for
the solutions in tomographic reconstruction. We will study and further
develop the use of artificially generated training sets for
incorporation of structural information about the solution.

projects. Applications must be written in English and submitted online
