Picking A Device
When using the solver it will default to using any available GPU as long as it has enough memory to support the number of voxels you have selected. If it can not it will fallback to using the next best device that has enough memory. However, you can also choose a different device type such as a CPU.
If you have multiple devices such as two GPUs you may want to force the solver to use one over the other. You can select a device by name by choosing manual in the preferred device drop down menu. You will see a new manual device field appear. You can choose a device from this field’s drop down menu. The menu may take a few seconds to appear as it is compiling a special function to list all available OpenCL devices. This will only be slow the first time you use it.
