Highly-parallel Graphics Processing Units (GPUs) can improve the speed of micromagnetic simulations significantly as compared to conventional computing using Central Processing Units (CPUs). The authors 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. They analyze the scaling and cost benefits of using cloud computing for micromagnetics.
