A prospect for computing in porous materials research: very large fluid flow simulations
A full steady-state fluid flow simulation in a porous material, represented with an unprecedented resolution for the given sample size, is reported. The presented advance in the state-of-the-art exposes new opportunities in porous materials research. The full steady-state simulation executed in a CPU-based supercomputer involves 163843 lattice cells out of which around 590 billion are fluid or pore sites. In a benchmark flow simulation on a GPU-based system, a sustained computational performance of 1.77 PFLOPS is observed with 16384 GPUs.
