"WebWhen working with multiple devices, you need to be careful with allocated memory: Allocations are tied to the device that was active when requesting the memory, and cannot be used with another device. That means you cannot allocate a CuArray, switch devices, and use that object. Similar restrictions apply to library objects, like CUFFT plans. " - Cufft unified memory
