Required configuration of the system

Hello All,

I’m new to this software. Could someone please advise on the minimum required specifications for a personal computer or laptop to run the software smoothly and fast? The simulations I plan to run may involve number of atoms approximately from 100,000 to 200,000.

Pretty much any current hardware can run LAMMPS. How fast or slow this runs and how slow is acceptable for you we cannot know.

The number of atoms is only one of the factors determining the speed. Choice of pair style, density, cutoff, treatment of long-range electrostatics, additional steps and fixes used, size of timestep, mass of particles and so on can all affect the performance. Thus, only a benchmark with a representative input deck can give you a meaningful assessment of the performance and the requirements on the hardware.

Thanks Axel
