use your gpu device as solver
If you have a Gpuenabled card, take advantage of the GPU chipset to make faster calculations. Enable this option at Scene>solver>gpu> Use GPU. This option is only available if your graphics card supports OPENCL-CPU. Speed up simulation by 3-8x compared to the CPU: The amount of VRAM determines the size of the simulation, and there is no fallback on the mainboard’s RAM.
