There is a great attention on researches where possible alternatives to the CMOS chip based computer systems are examined, such as the computer systems based on the principle of magnetic spin waves. Theoretically these systems have low-loss, high speed and possibly non-volatile memories. By using simulations the positioning of the spin based structures and their consequences, the outputs can be tested, namely the operations on the input is determined by the topology. The result is affected by the shape and the distance of the cells which transmits waves. The question of how to get from a series of input to the desired output can be determined by using genetic algorithm. In micro magnetic simulations one of the hardest part of the simulation is the computation of the magnetic field, which is a long-range interaction. The goal is the acceleration of a magnetic-field simulator based on FPGA.
