GPU memory issue while executing lmp

[mayankaditya]

Summary

Dear DeePMD developers,

I am running a machine-learned MD using the DeePMD package from docker. I am facing a memory issue while executing the LAMMPS simulations (provided with the DeePMD package) in the GPU server.
I am getting the following error:
2024-10-04 10:22:31.041258: W tensorflow/core/common_runtime/bfc_allocator.cc:474] _____***********************

It seems you only use 1 MPI rank. Each MPI rank can only use one card.

Each MPI rank can only use one card.

I realize this is not documented anywhere.
