Trott, WebDuring a simulation run LAMMPS collects information about how much time is spent in different sections of the code and thus can provide information for determining performance and load imbalance problems. This can be done at different levels of detail and accuracy. … LAMMPS runs on single processors or in parallel using message-passing …
WebSep 19, 2024 · Based on the input file, this simulation will run for 1.1x10 6 time steps, and produce a MD trajectory file named ave.out. The trajectory may be analyzed (discarding the first 100000 timesteps and using 10 blocks to estimate the uncertainty in the remaining 1000000 timesteps) via: >../analysis/block_analysis.py -f ave.out -b 10 -m 100000 WebJan 15, 2024 · For 4 processes a small simulation took 1 hour 20 minutes (lowest time). But when I simply run my simulation without any parallel process, it takes 1 hour 9 minutes. Later I tried this command using OPENMP package- “env OMP_NUM_THREADS=10 lmp -sf omp -in input.lammps” My simulation took only 24 minutes.
