Title: Stochastic Profiles of upcoming HPC Applications and their impact on Scheduling strategies Abstract: New applications with different profiles are coming to HPC infrastructures. We aim at better understanding the features and needs of these applications in order to be able to run them efficiently on HPC platforms. In this talk I will present…
A Brief History of Iterative Methods for Linear Systems Iterative methods for linear systems were invented for the same reasons as they are used today, namely to reduce computational cost. Gauss states in a letter to his friend Gerling in 1823: “you will in the future hardly eliminate directly, at…
Title : Lattice-Boltzmann methods for wind energy applications Abstract : One of the key players in overcoming climate change is the production of green and decarbonized electricity based on wind energy. Within the design process of wind farms, the reliable prediction of the power production of a farm is indispensable…
Title: Towards an inf-sup theory for the Biot equations in poroelasticity Abstract: In the theory of poroelasticity, the quasi-static Biot equations model the flow of a fluid inside a linear elastic porous medium. The equations have been previously analyzed by energy arguments, following the Faedo-Galerkin scheme, or via the operator…
Title: Dynamical response properties of molecules and solids Abstract: I will give an introduction to electronic structure computation, with the goal of obtaining the dynamical properties of some molecules and solids (absorption spectrum, resonances, etc.). I will be interested by the numerical approximation of these quantities, with a special focus…
Title: Optimization of pulmonary ventilation in humans and all mammals Summary: The primary function of the lung is to supply oxygen to the blood and deplete carbon dioxide from the blood. The lung transports respiratory gases by convection and diffusion through its tree-like geometry to an exchange surface called the…
Randomized sketching for Krylov approximations of large-scale matrix functions The computation of f(A)b, the action of a matrix function on a vector, is a task arising in many areas of scientific computing. In many applications, the matrix A is very large and hence computing f(A) explicitly is unfeasible. Here we…
