Libraries

Needs the PoisFFT package

https://github.com/LadaF/PoisFFT

You can install the library locally and add it to your path. E.g. Add the following to your .bashrc file:

export LD_LIBRARY_PATH=/home/pmocz/PoisFFT/lib/gcc:$LD_LIBRARY_PATH

To install this library, in your directory for libraries, you can do

git clone https://github.com/LadaF/PoisFFT.git
cd PoisFFT/
cd src/
scons

Also needs hdf5, fftw3

You will have to modify the Makefile to point to your library installations

How to run

recompile and run:

make clean; make; ./IntegerLattice 

to run in parallel (METHOD_MEMSAVE only):

mpirun -n 4 ./IntegerLattice

to compile job on odyssey:

./makeOdyssey.sh 

to submit job to a queue (e.g. odyssey cluster):

sbatch submit.sh

to plot snapshots (e.g. snaps 0, 10, 20, 30), in the analysis/ folder, run the python script:

python plot.py 0 10 20 30

or, to plot the snapshots run in parallel mode (split files), run:

python plotParallel.py 0 10 20 30
