This work introduces the development of a micromagnetic simulator running on highly parallel Graphics Processing Units (CPU's). We show how main components of the calculation (ODE solver and magnetic potential calculation) can be implemented to provide optimal speedup for various problem sizes. For smaller problems, direct potential calculation is the most efficient method, while large problems are...
We have adapted our finite element micromagnetic simulation software to the massively parallel architecture of graphical processing units (GPUs) with double-precision floating point accuracy. Using the example of Standard Problem #4 with different numbers of discretization points, we demonstrate the high speed performance of a single GPU compared with an OpenMP-parallelized version of the code using...
