Multi-GPU fast Fourier transforms in MATLAB (for large-scale phase-field crystal simulations)
Maik Punke, Marco Salvalaglio
We present a MATLAB-based framework for two- and three-dimensional fast Fourier transforms on multiple GPUs for large-scale numerical simulations using the pseudo-spectral Fourier…

Grain-Growth Stagnation from Vacancy-Diffusion-Limited Disconnection Climb
Maik Punke, Abel H. G. Milor, Marco Salvalaglio
Grain growth in polycrystals typically stagnates at long times. We identify disconnection climb, limited by vacancy diffusion, as a fundamental microscopic mechanism underlying thi…
