CosmoHammer: Cosmological parameter estimation with the MCMC Hammer

Abstract: CosmoHammer is a Python framework for the estimation of cosmological parameters. The software embeds the Python package emcee by Foreman-Mackey et al. (2012) and gives the user the possibility to plug in modules for the computation of any desired likelihood. The major goal of the software is to reduce the complexity when one wants to extend or replace the existing computation by modules which fit the user's needs as well as to provide the possibility to easily use large scale computing environments. CosmoHammer can efficiently distribute the MCMC sampling over thousands of cores on modern cloud computing infrastructure.

A new release of CosmoHammer is available. The package is now on GitHub (https://github.com/cosmo-ethz/CosmoHammer) and the package is downloadable at PyPI (https://pypi.python.org/pypi/cosmoHammer).

To upgrade to the newest version, please do:

$ pip install cosmohammer --user --upgrade

Slight changes have been made to the package structure; these require adaptions to the import statements. More information is available on CosmoHammer's new website at RTD: http://cosmohammer.readthedocs.org.

The link in the ASCL record has been changed from http://www.cosmology.ethz.ch/research/s ... ammer.html to the links listed above.
