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. ------------------------------------------------------- From: Veselin Dobrev [log in to unmask] Date: June 04, 2018 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.

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.

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/ You may apply for this position until 15 June 2018 by sending an email 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 ------------------------------------------------------- From: Matteo Giacomini [log in to unmask] Date: May 28, 2018 Subject: PhD Position, UPC-BarcelonaTech 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.
