MUMPSpy

A python wrapper for the parallel sparse direct solver.

The wrapper allows to:

• real and complex arithmetic
• parallel run
• Schur complement calculation

Requirements

• MUMPS - MUltifrontal Massively Parallel sparse direct Solver
• mpi4py - Python bindings for MPI

Ubuntu/Debian users can use the following command to install the required packages:

apt-get install python-mpi4py libmumps-dev

Installation

• Download the code from the git repository:

  git clone git://github.com/vlukes/mumpspy
  

or

• Use pip:

  pip install git+git://github.com/vlukes/mumpspy
  

Usage

import mumpspy

solver = mumpspy.MumpsSolver(system='real')  # initialize solver, real-valued system
solver.set_mtx_centralized(A)  # set sparse matrix
x = b.copy()
solver.set_rhs(x)  # set right-hand side
solver(6)  # analyse, factorize, solve
print x
del(solver)  # cleanup

Compatibility

Tested for the following MUMPS library versions:

• 4.10.0
• 5.0.1, 5.0.2
• 5.1.2
• 5.2.1
• 5.4.1
