When using unified memory on systems with CUDA GPUs, various types of memory advice can be applied to modify how the CUDA runtime moves this memory around between the CPU and GPU. One type of advice that can be applied is "preferred location", and you can specificy where you want the preferred location of the memory to be. This can be useful for ensuring that the memory is kept on the GPU.
By creating a pool on top of an umpire::strategy::AllocationAdvisor, you can amortize the cost of applying memory advice:

The complete example is included below:
