Hello everyone:
Currently, I use the command PMEMD.cuda to simulate my system.
And It's known that It's a waste of time to copy device(CUDA) data to Host frequently.
Every time I use the command gpu_download_crd, it downloads all of the coordinates of atoms.
But, in my system, I only need a small subset of atoms to download to my host and modify them, then upload it.
To my way of thinking, it would decrease the simulation time if I could download a small subset of atoms. Is my idea right? And it's possible for me to do this? If possible, how can I modify the source code to provide this ability?
