OpenFOAM acts as a major player in the Open Source CFD arena, due to its flexibility, but its
complexity also makes it more difficult to correctly define performance figure and scaling …

We address the development of a modular implementation of the MGRIT (MultiGrid‐In‐Time)
algorithm to solve linear and nonlinear systems that arise from the discretization of …

Heterogeneous architectures seem to be not only the present but also the future of the HPC
world (eg, see the Exascale Project of US Department of Energy or the European Horizon …

We consider linear systems that arise from the discretization of evolutionary models.
Typically, solution algorithms are based on a time-stepping approach, solving for one time …

OpenFOAM is a widely used open source framework for simulation in several areas of
computational fluid dynamics and engineering. As a partial differential equation (PDE) …

This work is the first dowel in a rather wide research activity in collaboration with Euro
Mediterranean Center for Climate Changes, aimed at introducing scalable approaches in …

SUMMARY Parallel in Time (PinT) methods have received renewed interest over the last
decade for improving the algorithmic scalability on emerging computer architectures of time …
