µFFT is a unified interface to serial and MPI-parallel FFT libraries, build on top of µGrid. µGrid and µFFT make it easy to implement algorithms that operate on fields, such as solving partial differential equations. It supports parallelization using domain decomposition implemented using the Message Passing Interface (MPI).
µFFT is written in C++ and currently has language bindings for Python.
This README contains only a small quick start guide. Please refer to the full documentation or the DeepWiki LLM-generated documentation for more help.
To install µFFT, run
pip install muFFT
Note that on most platforms this will install a binary wheel, that was compiled with a minimal configuration. To compile for your specific platform use
pip install -v --no-binary muFFT muFFT
which will compile the code. µFFT will autodetect µFFT will autodetect MPI, FFTW, MPIFFTW and PFFT. Monitor output to see which of these options were automatically detected.
