In this paper we describe the research and development activities in the Center for Efficient
Exascale Discretization within the US Exascale Computing Project, targeting state-of-the-art …

We present an acceleration method for sequences of large-scale linear systems, such as the
ones arising from the numerical solution of time-dependent partial differential equations …

We present a performance portable solver workflow for developing multiphase flow
simulations based on the OP2 domain-specific language. The workflow brings together the …

We study linear models for the prediction of the initial guess for the nonlinear Newton-
Raphson solver. These models use one or more of the previous simulation steps for …

The solution to the Poisson equation arising from the spectral element discretization of the
incompressible Navier-Stokes equation requires robust preconditioning strategies. Two …

The goal of this milestone was to help CEED-enabled ECP applications (particularly
ExaSMR, MARBL, ExaAM, ExaWind and E3SM) in their preparations for the Aurora and …

High Performance Computing (HPC) is a powerful tool in scientific research for experimental
simulation and data analysis. However, it has not been well studied and applied for …

The goal of this milestone was to improve the high-order software ecosystem for CEED-
enabled ECP applications by making progress on efficient matrix-free kernels targeting …

La simulation numérique des écoulements incompressibles avec des discrétisations (semi-)
implicites en temps implique la résolution d'un certain nombre de systèmes linéaires. Dans …
