# ------------------------------------------------------------------------
# The following simulation codes all run in parallel
# using ParMetis for mesh partitioning and MPI for
# parallel computation.
# First compile the ParMetis library
cd 3rdParty/ParMetis-3.1/
make
# you may need to adjust the paths for the MPI compilers in the Makefiles
# ------------------------------------------------------------------------
# To compile the CPU/MPI only codes:
# CPU+MPI+2d time-domain Maxwells (TM mode) with N=6
make -f MakefileCPU2d N=6 clean
make -f MakefileCPU2d N=6
# CPU+MPI+3d timw-domain Maxwells with N=6
make -f MakefileCPU3d N=6 clean
make -f MakefileCPU3d N=6
# ------------------------------------------------------------------------
# To compile the GPU/MPI only codes:
# NOTE FOR GPU CODES:
# 1. you may wish to change the device assignment made
# near the start of the main function in MaxwellsDriver#d.m
# 2. you will need to have nvidia's cuda framework installed
# and may need to adjust the path that the Makefiles use
# to search for the nvcc compiler, libraries and include
# files
# GPU+MPI+2d time-domain Maxwells (TM mode) with N=6
make -f MakefileGPU2d N=6 clean
make -f MakefileGPU2d N=6
# GPU+MPI+3d timw-domain Maxwells with N=6
make -f MakefileGPU3d N=6 clean
make -f MakefileGPU3d N=6
# ------------------------------------------------------------------------
# To run the various configurations (in serial) with sample meshes:
./MaxwellsCPU2d Meshes/block2.neu
./MaxwellsCPU3d Meshes/cubeK268.neu
./MaxwellsGPU2d Meshes/block2.neu
./MaxwellsGPU3d Meshes/cubeK268.neu
# ------------------------------------------------------------------------
# To run the various configurations (in parallel using MPI) with sample meshes:
mpirun -np 2 ./MaxwellsCPU2d Meshes/block2.neu
mpirun -np 2 ./MaxwellsCPU3d Meshes/cubeK268.neu
mpirun -np 2 ./MaxwellsGPU2d Meshes/block2.neu
mpirun -np 2 ./MaxwellsGPU3d Meshes/cubeK268.neu
# When running with multiple GPUs you may wish to adjust the device
# used by each cpu.
