Feature Description

Dear Developers:

I've tried run MD using Mattersim via ASE, however I found the speed is quite slow, I'm just wondering if there is anyway to accelarate the simulation? By the way, can I integrate Mattersim with LAMMPS? thanks so much.

Best wishes,
Lingjun

Motivation

1. To accelarate MD simulation;
2. To integrate with LAMMPS, which is quite fast.

Proposed Solution

No response

Contribution Interest

• I'm interested in potentially implementing this feature
• I can provide guidance, but cannot implement
• I'm just suggesting the feature for the community

Code of Conduct

• I agree to follow the project's Code of Conduct

Lingjun,

What hardware are you running the model on? The speed should be comparable to most GNN-based MLFFs.

We do have a LAMMPS interface. Just did not get the bandwidth to clean up the code and push that to the repo. So, while we welcome contribution from the community, for this case, I'd suggest wait a bit so as not to duplicate the work.

PS, interfacing with LAMMPS likely won't accelerate the simulation as the model inference bit is the most time-consuming part.

Dear Ziheng, The mattersim is a wonderful model however I've encountered some problems and would be really grateful if you can give me some advice. I'm using RTX3090, my system contains 3000 atoms and I've tested that it tooks about 4 hours to run 50 ps NVT using ASE, which would be too slow as I wish to inspect MSD, which may need simulation of about 10 ns, no idea if there is anyway I can accelerate the simulation? thanks so much. Best wishes, Lingjun
