Subject: BBComp: Black-Box Optimization Competition, Call for Participation

The Black Box Optimization Competition (BBComp,
https://bbcomp.ini.rub.de/) has opened five new tracks consisting of
challenging single- and multi-objective optimization problems. The
competition is organized in the scope of the Genetic and Evolutionary
Computation Conference (GECCO'2018, http://gecco-2018.sigevo.org/).

BBComp is the first competition platform in the continuous domain
where test problems are truly black boxes to participants. The only
information known to the optimizer and the participant is the
dimension of the problem, bounds on all variables, and a budget of
black box queries.

The competition is also the first web/online optimization competition
in evolutionary computation domain. It aims at attacking a growing
impact of over-fitting of optimization algorithms to a narrow set of
existing benchmark problems. The competition was run five times so
far, attracting more than 100 unique submissions, including some
state-of-the-art commercial solvers.

All the material including the source code in C/C++, MATLAB, Python
and Java is available at http://bbcomp.ini.rub.de . The results of the
competition will be announced during GECCO'2018. Participants do not
need to attend the conference or submit papers, they can even choose
to be anonymous to the other participants.

Subject: MFEM version 3.4

Version 3.4 of MFEM, a lightweight, general, scalable C++ library for
finite element methods, is now available at: http://mfem.org

The goal of MFEM is to enable high-performance scalable finite element
discretization research and application development on a wide variety
of platforms, ranging from laptops to exascale supercomputers.

It has many features, including:
 - 2D and 3D, arbitrary order H1, H(curl), H(div), L2, NURBS elements.
 - Parallel version scalable to hundreds of thousands of MPI cores.
 - Conforming/nonconforming adaptive mesh refinement (AMR), including
   anisotropic refinement, derefenement and parallel load balancing.
 - Galerkin, mixed, isogeometric, discontinuous Galerkin, hybridized,
   and DPG discretizations.
 - Support for triangular, quadrilateral, tetrahedral and hexahedral
   elements, including arbitrary order curvilinear meshes.
 - Scalable algebraic multigrid, time integrators, and eigensolvers.
 - Lightweight interactive OpenGL visualization with the MFEM-based
   GLVis tool.

Some of the new additions in version 3.4 are:
 - Significantly improved non-conforming unstructured AMR scalability.
 - Integration with PUMI, the Parallel Unstructured Mesh
   Infrastructure from RPI.
 - Block nonlinear operators and variable order NURBS.
 - Conduit Mesh Blueprint support.
 - General "high-order"-to-"low-order refined" field transfer.
 - New specialized time integrators (symplectic, generalized-alpha).
 - Twelve new examples and miniapps.

MFEM is being developed in CASC, LLNL and is freely available under
LGPL 2.1. For more details, see the interactive documentation and the
full CHANGELOG.

Subject: PhD Position, Discontinuous Galerkin Methods, Univ of Twente

In this 4 year PhD project at the Mathematics of Computational Science
Group in the Department of Applied Mathematics, University of Twente,
Enschede, The Netherlands, the focus will be on the development of
novel discontinuous Galerkin methods for the Maxwell equations to
study the absorption of light in photovoltaic cells. This will require
both the development of efficient numerical discretizations and
solvers for the Maxwell equations, their implementation in highly
efficient parallel solvers, and the modelling of the absorption of
light in complex nanophotonic media. The absorption of light is
modelled by considering absorption as a sequence of scattering events
and wave interference. This project requires significant advances in
both finite element methods to solve the Maxwell equations and in the
understanding of the absorption of light in nanophotonic media. The
main research topics are: 1. the development, analysis and
implementation of an efficient higher order accurate discontinuous
Galerkin finite element method and multigrid techniques to solve the
time-harmonic Maxwell equations; 2. to compute eigenchannels using a
singular value decomposition (SVD) and to use these results to study
the absorption of light in thin photovoltaic cells.

From: Roel Verstappen [log in to unmask]
Date: May 29, 2018
Subject: PhD Position, Parallel-in-Time, Univ of Groningen

A fully-funded 4 year PhD position starting August 1st, 2018 is
available in the Computation and Numerical Maths group at the
University of Groningen, Netherlands. The PhD-project aims to develop
parallel-in-time methods for the propagation of uncertainties in
wind-farm simulations. Wind-farm simulations have to resort to
coarse-grained models of the small scales of motion for which
numerical resolution is not available. The nonlinear propagation of
the resulting modeling uncertainties is studied numerically. To start,
a comparative study of surrogate models for uncertainty propagation
(UP) is performed and the best method is tailored to turbulence.  The
number of cores needed for this UP is so large that a space-only
parallelization does not suffice; hence parallel-in-time algorithms
are developed for this application.

We are looking for a motivated candidate with a Master degree that has
experience in Scientific Computing. The University of Groningen offers
a salary of 2,222 Euro gross per month in the first year to a maximum
of 2,840 Euro gross per month in the final year excluding a 8% holiday
allowance and a 8.3% end of the year bonus. The conditions of
employment are available at /www.rug.nl/about-us/work-with-us/

to [log in to unmask] The application should contain: your cv,
BSc/MSc transcripts and a brief description of previous research
experience, such as the bachelor/master research projects

One PhD position is available in Prof. Antonio Huerta's group within
the Laboratori de Calcul Numeric (LaCaN) at Universitat Politecnica de
Catalunya, BarcelonaTech.

The project focuses on the development of high-order finite element
methods for the high-fidelity simulation of multiphysics coupled
problems involving electromagnetic phenomena (e.g. metamaterials,
magnetohydrodynamics, ...) and reduced order models techniques for
real- time solution of parameterized partial differential equations.

The research will be developed under the supervision of Prof. Antonio
Huerta and Dr. Matteo Giacomini (UPC), in close collaboration with Dr.
Ruben Sevilla (Swansea University, UK). The project is funded by means
of a 4-year fellowship within the framework of the Spanish Plan
Nacional CrediblE "Data assimilation for Credible Engineering
simulations". The prospective PhD student is expected to start
immediately or in September 2018.

Requirements: MSc degree (or equivalent) in mathematics, engineering
or related disciplines; knowledge of numerical methods for the
approximation of partial differential equations (in particular, the
finite element method); good programming skills (Matlab and/or
Fortran); hard-working and enthusiastic attitude; curiosity and
commitment to develop high-quality research.

and MSc studies, a motivation letter and the contacts of at least two
academic references to [log in to unmask]

University and The University of Texas at Austin, and will be
co-supervised by Prof. Paolo Bientinesi (RWTH) and Prof. Robert van de
Geijn (UT Austin). Research stays at UT Austin are expected.

The appointments --either at the payscale TVL-13 (about 3600
Euros/month gross at the entry level [2]) or as a tax-free stipend
(2000 Euros/month net)-- will be initially for one year, and will be
extended for two extra years upon positive evaluation.

Applications from excellent candidates are invited.  To apply, please
