For single GPU runs (i.e. 4 independent jobs) then things should be fine
assuming the I/O can keep up etc. The caveat with that is that I have not
actually tried 4 GPUs in a single socket machine with a 4 core GPU so am
speaking from a theoretical standpoint here given how the AMBER GPU code
works. Someone else who is running such a system might want to chime in with
some specific performance numbers if they have them.

All the best
