Abstract We present M u M ax , a general-purpose micromagnetic simulation tool running on graphical processing units (GPUs). M u M ax is designed for high-performance computations and specifically targets large simulations. In that case speedups of over a factor 100 × can be obtained compared to the CPU-based OOMMF program developed at NIST. M u M ax aims to be general and broadly applicable. It solves the classical Landau–Lifshitz equation taking into account the magnetostatic, exchange and anisotropy interactions, thermal effects and spin-transfer torque. Periodic boundary conditions can optionally be imposed. A spatial discretization using finite differences in two or three dimensions can be employed. M u M ax is publicly available as open-source software. It can thus be freely used and extended by community. Due to its high computational performance, M u M ax should open up the possibility of running extensive simulations that would be nearly inaccessible with typical CPU-based simulators.
