  Highly-parallel graphics processing units (GPUs) can improve the speed of
micromagnetic simulations significantly as compared to conventional computing
using central processing units (CPUs). We present a strategy for performing
GPU-accelerated micromagnetic simulations by utilizing cost-effective GPU
access offered by cloud computing services with an open-source Python-based
program for running the MuMax3 micromagnetics code remotely. We analyze the
scaling and cost benefits of using cloud computing for micromagnetics.
