CREDO

CREDO is a toolkit for running, analysing and benchmarking computational models.

CREDO was originally developed to support better benchmarking and profiling of the Underworld Geophysics modelling application, based on the StGermain framework. For more on Underworld (and StGermain), see the Underworld website.

For more details about the design of CREDO and how to run it, see the documentation in the doc sub-directory.

This fork of CREDO was developed at the University of Auckland for benchmarking the Waiwera geothermal flow simulator.

Basic Installation instructions

The Waiwera fork of CREDO can be installed from PyPI using pip, e.g. pip install waiwera-credo (or pip install --user waiwera-credo to install locally, e.g. if you don't have permissions to install system-wide Python packages).

The installation instructions for the original CREDO toolkit are below.

(For more detailed installation instructions, see the "Installation & setup quickstart instructions" section of the CREDO documentation.)

To run CREDO scripts directly from the command line, you need to set up several environment variables. These are:

• STG_BASEDIR: the path where your StGermain-based app has been checked out and installed to.
• PYTHONPATH: You'll need to update your Python Path to include a reference to the directory you installed CREDO into.

In the application bundle CREDO was distributed as part of, there should be a script you can edit to easily update these variables and then source, such as "updatePathsCREDO.sh".

After that, you should be good to go!

If you wish to build a local copy of the CREDO documentation, you will need to first install the 'Sphinx' documentation tool, and the 'Graphviz' plotting library (for more on these see the doc appendix). Then:

1. cd doc
2. make html
3. make latex; pushd _build/latex; make all-pdf; popd

The documentation will then have been built in the _build subdirectory of doc.
