CosmoMC

CosmoMC:Fortran 2008 parallelized MCMC sampler (general and cosmology)
Homepage:http://cosmologist.info/cosmomc/

Description and installation

For full details see the ReadMe.

Algorithm details

See the latest paper.

GetDist

CosmoMC includes the GetDist python sample analysis and plotting package, which is also available separately.

Branches

The master branch contains latest changes to the main release version.

https://secure.travis-ci.org/cmbant/CosmoMC.png?branch=master

The devel branch is a development version, using CAMB devel branch which integrates CAMB and CAMB sources (though CAMB sources functions are not available via CosmoMC yet). Includes run-time changing of dark energy model between fluid and PPF modes (easily extended). Shared general function now taken from the forutils library.

https://secure.travis-ci.org/cmbant/CosmoMC.png?branch=devel

Both branches now have a travis unit test to check they work with the Planck 2015 data. The test does a test install of forutils, CosmoMC and the Planck likelihood code and checks the likelihood is as expected. See tests/run_tests.sh for the setup and test code. There are small changes in the absolute likelihood value between branches due to small changes in the CAMB version (e.g. implied optical depth changes very slightly due to changes in time sampling).
