Thanks Mark, That really helped to clarify how everything is interacting around the verlet scheme. What statistics do you recommend examining between nstpcouple settings? Pressure/box size variation is the obvious one but I was curious whether you had something else in mind. -Trayder On Thu, May

Hi all, I've been running 5fs timestep simulations successfully without gpus (united-atom, HEAVYH). When continuing the same simulations on a gpu cluster utilising the verlet cutoff-scheme they crash within 20 steps. Reducing the timestep to 2fs runs smoothly, however I noticed the message: Maki
