Docker上でLAMMPSの計算実行
docker imageのIDを確認.
docker image ls
stdout:
REPOSITORY TAG IMAGE ID CREATED SIZE
lammps/lammps stable_29Sep2021_ubuntu20.04_openmpi_py3 4ce3adcff72f 2 years ago 1.85GB
lammps/lammps latest 1aceb06072da 3 years ago 1.85GB
今回は,IMAGE IDが4ce3adcff72fのものを使用する.
以下のように,LAMMPSのコマンドを実行.
docker container run --volume $(pwd):/home/lammps -it 4ce3adcff72f mpirun -np 2 lmp_mpi -i Ar_npt.in
計算が実行された.
