If you run into problems with CMake not being able to find your local FFTW3 or HDF5 installation, it is best to give the path directly as
FFTW3_ROOT=<path> HDF5_ROOT=<path> ccmake ..
make sure to delete previous files generated by CMake before reconfiguring like this.

## Running
There is an example parameter file 'example.conf' in the main directory. Possible options are explained in it, it can be run
as a simple argument, e.g. from within the build directory:
./monofonic ../example.conf
If you want to run with MPI, you need to enable MPI support via ccmake. Then you can launch in hybrid MPI+threads mode by
specifying the desired number of threads per task in the config file, and the number of tasks to be launched via
mpirun -np 16 ./monofonic <path to config file>
It will then run with 16 tasks times the number of threads per task specified in the config file.
