If you want to request both GPUs, you can set -gres=gpu:2. LAMMPS can produce on-the-fly JPG or PNG snapshot images via its dump image command. Note that besides the nodal/atomic positions, the energy. Note that you will always get at least 12 tasks (cores) if you request one GPU. These files, created by vtklegacy.f90 with a frequency of outputfreq, can be read by ParaView. This will start LAMMPS on 12 cores and 1 GPU. #Lammps output for paraview codeLAMMPS and C code for measuring velocity and peak frequency output from. Module load LAMMPS/11Aug17-foss-2018a-CUDA-9.1.85 LAMMPS, ParaView and C code development and testing will occur on a local Linux. Dump files, which contain snapshots of atoms and various per-atom values and are written at a specified frequency. The job specification for a single-GPU LAMMPS job should look like this: 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. 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. This depends on the ParaView version and the type of rendering, namely GPU accelerated rendering or software. #Lammps output for paraview how toThe data is passed in transit through libIS and our SENSEI interface, saved to disk using the VTK I/O backend in SENSEI. There are certain diffences how to start ParaView. 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. Interactive visualization of a LAMMPS simulation with two ranks in ParaView. ![]()
