How To Install python3-mpi4py-fft on Debian 12
Introduction
In this tutorial we learn how to install python3-mpi4py-fft on Debian 12.
What is python3-mpi4py-fft
python3-mpi4py-fft is:
mpi4py-fft is a Python package for computing Fast Fourier Transforms (FFTs). Large arrays are distributed and communications are handled under the hood by MPI for Python (mpi4py). To distribute large arrays we are using a new and completely generic algorithm that allows for any index set of a multidimensional array to be distributed. We can distribute just one index (a slab decomposition), two index sets (pencil decomposition) or even more for higher-dimensional arrays.
In mpi4py-fft there is also included a Python interface to the FFTW library. This interface can be used without MPI, much like pyfftw, and even for real-to-real transforms, like discrete cosine or sine transforms.
The package provides a Python interface to FFTW, but with MPI parallelisation. This enables strong scaling tested to 16000 cores, or weak scaling tested to 2000 cores. The algorithm is documented at https://arxiv.org/abs/1804.09536
This package installs the library for Python 3.
There are three methods to install python3-mpi4py-fft on Debian 12. We can use apt-get, apt and aptitude. In the following sections we will describe each method. You can choose one of them.
