Srun -n 4 lmp_CUDA -sf gpu -pk gpu 2 < in. the postprocessing of the simulation results with ParaView are part of the document. browser environment and embeds the live javascript output into the notebook.

In case you want to run with fewer MPI tasks, you can use srun’s -n option: such as ase.gui, RasMol, VMD, gOpenMol, Avogadro, ParaView or NGLView. 4 Load LAMMPS Dump File From File menu: Open Choose LAMMPS Dump Files In Properties tab: Check mesh Uncheck unitcell Check id and species Click Apply. This will automatically allocate all 24 cores of the machine to your job, which you can also make explicit by setting -ntasks-per-node=24.įor two GPUs, you will have to instruct LAMMPS that it can use both of the GPUs: If you want to request both GPUs, you can set -gres=gpu:2. For example /OpenFOAM-4.1/cases/cylinder/. LAMMPS output can be processed by the Pizza.py toolkit in various ways to produce plots and pictures and animations. Creating a ParaView Python script Ensure that all paths including output images are written to a valid relative path.

However it's output can be directly used by several post-processing and viz tools that are distributed with the LAMMPS package in the tools directory.

Note that you will always get at least 12 tasks (cores) if you request one GPU. LAMMPS itself does not do post-processing or visualization. To output the results of this compute in your dump file, you must use the LAMMPS dump command, as dump all custom id type.

Dump files, which contain snapshots of atoms and various per-atom values and are written at a specified frequency. This will start LAMMPS on 12 cores and 1 GPU. Output from LAMMPS (thermo, dumps, computes, fixes, variables) There are four basic kinds of LAMMPS output: Thermodynamic output, which is a list of quantities printed every few timesteps to the screen and logfile. The job specification for a single-GPU LAMMPS job should look like this: Some example and more information can be found at Github.Ī version of LAMMPS which has the GPU package included is available on Peregrine as a separate module, one with CUDA in its name. LAMMPS can make use of a GPU by using the GPU package the KOKKOS package can do this as well, but it’s not installed at the moment.
