FIESTA: Field Interpolation and Estimation using Spatial Techniques and Algorithms
Introduction
FIESTA is a python library for general interpolation from uniform and non-uniform input points. The library is written in python with numba acceleration for speed. The library has the optional capability to be used on large data-sets by distributing jobs across multiple processes via MPI. This relies on the mpi4py library and the MPI object from the shift-fft package (see here) which is passed as an additional object into MPI related functions.
Dependencies
Installation
FIESTA can be installed via pip:
pip install fiesta-pkg
or by cloning the repository:
git clone https://github.com/knaidoo29/fiesta.git
cd FIESTA
pip install .
Once this is done you should be able to call fiesta from python:
import fiesta
To use the MPI functionality please take a look at the documentation in FIESTA which instructs users how to use the shift-fft MPI object and how to run these distributed jobs successfully without errors or MPI related hanging.
Showcase
