Abstract:
In the next years, the first Exascale class supercomputers will go online. In this paper, we portray a prospective Exascale scenario for a Lattice Boltzmann (LB) code, based on the performance obtained exploiting an up-to-date Petascale HPC facility. Although extrapolation is always a perilous exercise, in this work we aim to lay down a few guidelines to help the LBM community to carefully plan larger and more complex simulations using the forthcoming Exascale supercomputer machines.
