PyZoltan: a Python wrapper for the Zoltan library

PyZoltan is as the name suggests, is a Python wrapper for the Zoltan data management library.

In PyZoltan, we wrap the specific routines and objects that we wish to use. The following features of Zoltan are currently supported:

• Dynamic load balancing using geometric algorithms
• Unstructured point-to-point communication
• Distributed data directories

Installation

PyZoltan requires the following:

• numpy
• cyarray
• Cython
• mpi4py
• Zoltan

Zoltan itself needs to be already installed. We provide a convenient script called build_zoltan.sh that can be used to build Zoltan.

Many of the other dependencies can be installed using pip or conda:

$ pip install -r requirements.txt

Once this is installed one can install PyZoltan as follows:

$ pip install pyzoltan

or via the usual setup.py method:

$ python setup.py install # or develop
