This directory contains the inputs, outputs, job submission scripts and github hashes used to generate perform our simulations and create the figures presented in "A Massively Parallel Time-Domain Coupled Electrodynamics-Micromagnetics Solver" by Yao et al. and submitted to "The International Journal of High Performance Computing Applications." The source code for ARTEMIS is here https://github.com/ECP-WarpX/artemis.git (Commit hash used : 64e32d56767e6f8027de81a8c4897b808f211267) and AMReX code is here : https://github.com/AMReX-Codes/amrex.git (Commit hash : 7c3e95210a1877c67139ea57c62fbcc717acc1c3) The following modules were loaded for performing simulations on NERSC Cori GPU: 1) cgpu 2) gcc 3) cuda/10.2.89 4)mvapich2 and on NERSC Haswell Partition 1) modules/3.2.11.4 2) altd/2.0 3) darshan/3.2.1 4) craype-network-aries 5) gcc/8.3.0 6) craype/2.6.2 7) cray-mpich/7.7.10 8) craype-haswell 9) craype-hugepages2M 10) cray-libsci/19.06.1 11) udreg/2.3.2-7.0.1.1_3.47__g8175d3d.ari 12) ugni/6.0.14.0-7.0.1.1_7.49__ge78e5b0.ari 13) pmi/5.0.14 14) dmapp/7.1.1-7.0.1.1_4.61__g38cf134.ari 15) gni-headers/5.0.12.0-7.0.1.1_6.36__g3b1768f.ari 16) xpmem/2.2.20-7.0.1.1_4.20__g0475745.ari 17) job/2.2.4-7.0.1.1_3.47__g36b56f4.ari 18) dvs/2.12_2.2.165-7.0.1.1_14.4__ge967908e 19) alps/6.6.58-7.0.1.1_6.19__g437d88db.ari 20) rca/2.2.20-7.0.1.1_4.61__g8e3fb5b.ari 21) atp/2.1.3 22) PrgEnv-gnu/6.0.5 The input files, datasets, and jupyter notebooks (StrongScaling/strong_scaling_analysis.ipynb and WeakScaling/weak_scaling_plots.ipynb) used to generate the weak and strong scaling for CPU and GPU performance, shown in Figures 2, 3(a) and 3(b), are in the directory named "InputFilesAndDataSetForScalingStudies". The simulation data sets and analysis scripts for Figures 5, 6, and 7 in the paper are in the directory named "DataSetForEmptyWaveguideAndTunableFilter.tar.gz". The runs for the waveguide simulations used to produce Figures 5, 6, and 7 were run on a local LBNL work-station with a single NVIDIA Quadro GV100 GPU. The input files are located in the ARTEMIS repository (https://github.com/ECP-WarpX/artemis.git) at Examples/Waveguide/.
