Hi!

I am using a custom tabulated potential and a **cutoff-scheme = group**. Since I am using this option as the cutoff-scheme, it doesn’t allow me to use more GPUs in my simulation.

Is there a way to speed up my simulation using **cutoff-scheme = group**?

I can’t use **cutoff-scheme = Verlet** because I need to use the tabulated potential.

Thanks!

No, unfortunately this is not possible.

We still plan to add back the tabulated potentials, and then also support GPUs, but we need to find the resources for that.
