The function deepmd.infer.DeepDipole.eval() cannot utilize multiple GPUs in parallel #2877
Comments

I guess that this error stems from the lack of support for multi-GPU parallelization of inference from python api. @njzjz Is that true? @Kehan-Cai-nanako Can you try to use LAMMPS's |

The error arises when I only input one frame, i.e., the initial
configuration of the simulation.

Do you input one frame or multiple frames? Currently DeepTensor does not
support automatic batch size, unlike DeepPot, so this may cause OOM.
@Yi-FanLi <https://github.com/Yi-FanLi> You can try to support it. See

By the way, the size of the system is 34560 atoms + 27548 ghost atoms,
which may be relatively large for the memory capacity of GPU. ( The
simulation used DPLR. )

It's a little bit weird because you only have 1 frame and ~30k atoms. With an energy model based on the se_e2_a descriptor, an 80GB A100 can bear ~1000k atoms. @njzjz I think we need to do a more detailed analysis of the memory use in DeepTensor's inference. |

We concluded that this issue is due to the system being too large for the GPU version of the Python interface. More specifically, the neighbor list is too large so it cannot be allocated on the GPU. The workaround is to use LAMMPS's rerun command and use the compute deeptensor/atom command in LAMMPS. |

Thank you for the clarification.

With #3046, I can now run the script, so I think this issue has been resolved. output: I note that ASE may not be the fastest implementation. One can use other implementations but convert them to the ASE interface. |
Bug summary
When using the function deepmd.infer.DeepDipole.eval() to infer Wannier centroids, even though I requested multiple GPUs, only one of them is used in practice, while others are in idle state. Namely, the function feed all information of atomic positions into one GPU, and this may trigger the out-of-memory error when the size of the simulation system is large.
