Thanks much! I was assuming this functionality enables data to be prefetched to GPU (via CPU), but looks like from your explanation it is limited to CPU memory (and that is rather what I must monitor for noting performance gains). Although this functionality would be helpful, I guess it would still result in a squarish waveform for GPU utilization (idle times). I have actually tried calling cuda within getitem in the past with little success (I remember the code threw errors but might try again).
