So, Replica exchange simulations cannot be run on a system with only 1 GPU?

Hello Nikolay,
Replica exchange simulations require an even number of GPUs. This is because the number of replicas needs to be even.

Dear AMBER users and developers,
I would like to ask you if the pmemd.cuda (pmemd.cuda.mpi) code can use all 3 GPUs at once for a replica exchange MD simulation.
I mean the situation when a workstation has exactly 3 GPUs.
Does it depend on the number of replicas employed?
Kind regards,
Nick
