This is the python module to use SHTns, a high performance spherical harmonic transform and rotation library. It requires FFTW installed in your system.
GETTING STARTED
Basic Installation:
-
make sure FFTW is installed in your system; if not, install it using your system package manager.
-
run:
pip install shtns
This simple installation should work and be enough for most use cases. However, in order to have the highest possible performance, FFTW should be compiled and tuned for your machine, which is not the case with pre-compiled system packages.
Cuda GPU support:
Make sure the environment variable CUDA_PATH points to the installed cuda toolkit before running pip install shtns.
This will automatically add transparent support for nvidia gpus, in "offload" mode (that means data transfers are
performed by shtns).
Example code:
See https://bitbucket.org/nschaeff/shtns/src/master/examples/SHT_example.py and https://bitbucket.org/nschaeff/shtns/src/master/examples/shallow_water.py. For using the GPU from python, see https://bitbucket.org/nschaeff/shtns/src/master/examples/SHT_gpu_example.py
