      Can GPU be used to improve calculations and to save time?nGPU acceleration is an interesting technology with significant potential, but like everything, trade-offs are involved.nAt this point, our FDTD solver does not support GPU acceleration.nIf you are thinking about purchasing new hardware to make your simulations run faster, the best option is a multi-processor computer.nThese systems provide good performance because each processor has it?s own memory bus connection to the RAM.nSimulation speeds are typically limited by the memory bandwidth between RAM and processor, so having one memory bus per processor means the simulation speed tends to scale well with the number of processors. ????nSee Also:nDetermining optimum resource configuration for FDTDnTips on running FDTD simulations
